Screw Adjustment - Valve can be

adjusted with an allen wrench. Lock
nut included to maintain desired
setting after adjustment. This is the
most common adjustment option
available on most Parker products.

Tamper Resistant - The tamper

resistant option is a screw adjustable
valve with a steel cap installed to
conceal the adjustment. The cap is
designed so that the internal edges
clamp into the groove of the valve
adapter. Once the cap is installed,
it cannot be removed without damaging
the cap and the valve. When a valve is ordered with
the tamper resistant option, it will be preset at the
factory, and the cap will be included in a separate
plastic bag to allow for fine tuning at the customer site.
Parker offers tamper resistant cap conversion kits for
most pressure control valves. For kit numbers consult
individual valve pages.

Direct Acting Relief Valves

Direct acting relief valves are designed
for fast response in intermittent duty
applications. They are often used as an
economical solution to clip pressure spikes.
The poppet design allows for low leakage.

OPERATION - The valve poppet is held against the seat by the

spring force. Inlet pressure on the nose (port 1) of the poppet acts
against the spring force to unseat the poppet at the valve setting and allow flow to pass to tank. Since the
pressure is working directly on the spring, this valve is very fast responding. It is not the best choice for system
pressure regulation as it is slightly noisier than pilot operated relief valves and has higher pressure rise.
Note: Any backpressure on port 2 would be additive to the spring setting.

Differential Area Relief Valves

Differential area relief valves also are
also best suited for intermittent appliTank
cations where fast response is critical.
(1)
These valves are often used as crossover relief valves to chop pressure spikes.
Due to their design, they generally can handle a larger flow
rate and have a lower pressure rise than the standard directing
acting relief. The poppet design allows for low leakage.

Pressure
(2)

OPERATION - Pressure on the inlet (port 2) of the valve acts on the differential area of the poppet (difference
between the O.D. of the poppet and the seat diameter) to produce a force which is opposed by the spring force.
When pressure reaches the valve setting, the poppet is pushed off its seat, permitting flow to tank.
Note: Any backpressure on port 1 would be additive to the spring setting.

OPERATION - The fixed differential is provided by the pilot piston which has greater area than the dart seat. With
its greater area, the piston is able to hold the dart off its seat, permitting flow from pressure to tank, until pressure
on the pilot piston falls below the fixed percentage of the valve settings.

OPERATION - Pressure at port 1 acts on the spool to produce a force which is opposed by the spring setting.
When pressure reaches the valve setting, the spool and poppet move relieving flow from port 1 to port 2. When
port 2 is pressurized, the pressure acts on the differential area poppet to produce a force which is opposed by the
spring force. When the pressure reaches the valve setting, the poppet is pushed off of its seat, relieving flow from
port 2 to port 1. Note: Due to the construction and flow paths through the valve, the relief pressure settings may
vary by approximately 300 psi from one direction to the other.

Flow
Controls

OPERATION - This valve can be controlled by the adjustment

setting on the valve, or a remote circuit via the vent line. When the vent line
is used, the smaller of the two pressure settings will determine the valve setting. In other words, if the pressure
setting of the remote circuit is less than the adjusted setting, then the valve will relieve at the remote setting. If the
pressure setting of the remote circuit is greater than the adjusted setting, then the valve will relieve at the adjusted
setting. With the vent port (port 2) blocked, the valve operates like a standard pilot operated relief valve. Thus, a
solenoid valve could be used on the vent port to select control between this valve another remote valve.

Pilot Operated Reducing Valve

Pilot operated pressure reducing valves
can be used to reduce the pressure in
a leg of the circuit lower than system
pressure. Thus, they can be used to
provide protection to downstream
components from higher pressures.

Press. Inlet (2)

(3) Drain

Reg.
Press.
(1)

OPERATION - The pilot section controls the valve setting when

reducing. As pressure at the regulated port exceeds the valve setting,
the pilot ball is unseated. The pilot flow creates a pressure imbalance across the
main spool causing the spool to throttle in order to maintain constant downstream pressure. The normally open
design will allow flow to pass from inlet to reduced port with the only restriction being the pressure drop.

Pressure Reducing / Relieving Valves

Pressure reducing / relieving valves can be used to reduce the pressure in a leg of the
circuit lower than system pressure. The valve also acts as a relief valve, relieving any
shocks or surges that occur between the regulated port and the actuator. When the valve
is in the relieving mode, the inlet port is blocked. Parker offers pressure reducing/relieving
valves in both pilot operated and directing acting styles. The direct acting version is generally
used in static applications where response is critical, or leakage is a concern.

OPERATION - As pressure at the regulated port exceeds

which could lead to instability.

Pilot Operated Sequence Valves

Sequence valves are used to control the sequence of operation of two or more hydraulic actuators. The sequence
valve pressure is set higher than the first actuator operation pressure. Once the first actuator has completed its
cycle, the sequence valve opens allowing the second actuator to move. Parkers line of pilot operated sequence
valves include a series of internally piloted, externally drained valves and a series of externally piloted, internally
vented valves. Parker also offers a line of direct acting sequence valves which are ideal for piloting logic elements
in steady state applications.

LM

Press. Inlet (2)

(3) Sequence
P.O. Sequence (Externally Piloted, Internally Vented)
OPERATION - For this valve, the pilot pressure is obtained
Pilot
(1)
from an external source and not from the pressure port.
When the external pilot pressure (port 1) exceeds the valve
setting, the pilot section opens creating a pressure imbalance
across the main spool. This causes the spool to move allowing
the flow to pass from the side of the cartridge (port 2) to the actuator port (port 3).
Any pressure at port 3 is additive to the pressure setting. It is most common for port 3 to be connected to tank.

PC

D.A. Sequence (Internally Piloted, Externally Drained)

OPERATION - In the steady state condition,
all three ports are blocked with the spring

chamber drained to port 3. When the

pressure at port 1 exceeds the valve
setting, the spool moves allowing flow from
the nose of the cartridge (port 1) to the
actuator port (port 2). By externally draining the spring
chamber directly to tank (port 3), the valve is insensitive to back pressure at the sequence port.

(1)
exceeds the valve setting, the spool moves
opening a path and allowing flow from
port 3 to port 2. This valve internally drains
the spring chamber to tank via the sequencing port,
thus any backpressure on port 2 would be additive to the spring setting.

D.A. Sequence, N.O. (Externally Piloted, Externally Drained)

OPERATION - With no pressure at the pilot
port (port 1), bi-directional flow is allowed

(3)
(4)
between port 3 and port 2. When the pilot
(1)
pressure at port 1 exceeds the valve setting
the spool moves blocking both port 3 and
port 2. By externally draining the spring
chamber to tank (port 4), the valve is insensitive to back pressure at the sequencing ports.

Sequence (2)
(3) Drain
P.O. Sequence (Internally Piloted, Externally Drained)
OPERATION - For this valve, the pilot pressure is sensed
Press.
(1)
from the inlet of the valve (port 1). When the pilot pressure
exceeds the valve setting, the pilot section opens creating a
pressure imbalance across the main spool. This causes the
spool to move allowing the flow to pass from the nose of the
cartridge (port 1) to the actuator port (port 2). By externally draining the pilot flow
directly to tank (port 3), the valve is insensitive to back pressure at the sequence port.

Dual Cross-Over Relief Valve with

Motor Mount. This valve provides
overload and shock protection for
small gerotor motors with a manifold
mounting pattern, such as the Parker TB
and TE series. Close coupling the valve to the motor
provides ideal protection and eliminates plumbing.
For additional information see Technical Tips on
pages PC1-PC6.

Fast acting differential area reliefs for high flow capacity

D-Ring eliminates backup rings

Spherical poppets for low leakage

Internal mechanical stop limits poppet travel eliminating
spring solidification

Direct Acting Sequence Valve

(Internally Piloted, Externally
Drained). In the steady state
condition, all three ports are blocked
with the spring chamber drained to port 3.
When the pressure at port 1 exceeds the valve setting,
the spool moves allowing flow from the nose of the
cartridge (port 1) to the actuator port (port 2). By
externally draining the spring chamber directly to tank
(port 3), the valve is insensitive to back pressure at the
sequence port.

Direct Acting, Normally Closed

Sequence Valve (Externally Piloted).
With no pressure at the pilot port
(port 1), both port 3 and port 2 are
blocked. When the pilot pressure at port 1
exceeds the valve setting, the spool moves opening a
path and allowing flow from port 3 to port 2. This valve
internally drains the spring chamber to tank via the
sequencing port, thus any backpressure on port 2
would be additive to the spring setting.

Load/Motor
Controls

Direct Acting, Normally Open

Sequence Valve (Externally Piloted,
Externally Drained). With no pressure
at the pilot port (port 1), bi-directional
flow is allowed between port 3 and port 2.
When the pilot pressure at port 1 exceeds the valve
setting the spool moves blocking both port 3 and port
2. By externally draining the spring chamber to tank
(port 4), the valve is insensitive to back pressure at the
sequencing ports.
