15 Nut 1 PVC
1. When the upstream fluid pressure, P1, is
16 O-Ring (A) 1 EPDM
introduced at the flow control orifice, it exerts a
responding pressure on the upper surface of the 17 O-Ring (B) 1 EPDM
flange on the piston type valve plug. 18 O-Ring (C) 1 EPDM
19 O-Ring (D) 1 EPDM
2. Likewise, the downstream pressure, P2,
exerts a corresponding pressure to the lower surface 20 Key 2 PP
of the valve plug flange. 21 Thrust Ring 1 PP
22 Handle Base 1 PVC
3. Thus, when a differential exists between the
fluid upstream and downstream of the orifice, the 23 Handle Cover 1 PVC

VALVE OPENING (%)
This table shows the relationship between valve opening and Cv values.
Each curve is the representative average of all sizes for a particular type of
valve. Cv value is the percentage of the full open Cv. The Cv value can be
found in the appropriate section of this catalog.

Using the Cv value to calculate the differential Cv is the flow rate through a valve which will produce a
pressure or flow rate through a valve: differential pressure of 1 psi.

Whenever a fluid passes through a valve, there will

be a drop in pressure. The upstream pressure less

the downstream pressure is know as the differential Q = Cv√(∆P/s.g.)

 Westlock Top-Mounted Switch Box
A limit switch box is mounted on and coupled to the actuator in order to operate position-indicating lights on
control panels, to control other equipment such as pumps, compressors and mixers, to sequence other valves,
or for feedback and PLC position confirmation. Two single pole, double throw (SPDT) switches are mounted in
one enclosure and are activated by individual, adjustable cams.

The cams are connected to the cam shaft, which is directly coupled to the actuator shaft. Switches can be set
to be activated in fully open or closed positions, or in any position in the quadrant of the actuator's operation.

The limit switch box is available in Type 4X and Type 7 enclosures, and switches can be supplied in mechanical
or proximity models.

The electrical rating of the standard mechanical switches is 15 amps at 250 VAC, which qualifies them for the
following voltages: 12 and 24 VDC, 12, 24 and 115 VAC.

 Pneumatic Actuators with Solenoid
The solenoid valve used for our pneumatic actuators is a four-way, on/off, electrically controlled valve. An electrical
signal to the solenoid's coil switches the compressed air supply to the appropriate actuator ports.

The solenoids are furnished with mufflers and speed controls. The muffler reduces the sound of the exhausting
air, and the speed control determines the cycle time of the actuator. The speed controls are manually set needle
valves, which can be adjusted. The cycle time can be slowed by restricting the flow of the exhausting air, thus
maintaining back pressure on the opposite side of the pressured actuator cavity.

During the absence of electric power, the actuator can be cycled by operating the manual override on the solenoid,
providing that supply air is still available

Upon electric failure, actuators will return to the de-energized position. This position can be either actuator position,
depending upon how the plumbing is connected from the solenoid block to the air connection of the actuator.

 Series 92 Protek Battery Pack
The Quarter master Protek failsafe electric actuator features
a rechargeable battery pack, a built-in trickle charger, a low
battery indicator, and an auxiliary limit switch that is calibrated
with the fail position. The battery pack is installed inside of the
actuator housing, so a separate enclosure to house the battery
in not required.

When power is received from the primary power source, it is

directed to the actuator motor and switches for normal cycling
of the actuator. When the primary power source is interrupted,
the battery pack is then connected to the motor and switches,
and powers the actuator to the failsafe position. In this failsafe
position, the auxiliary limit switch is tripped, and can be wired
to an alarm. Once the primary power source is restored, the
battery pack is disconnected and normal operation resumes.

Series 94 Protek Battery Pack
The Quarter Master Protek Failsafe electric actuator
features a rechargeable battery pack a built-in trickle
charger, a low battery indicator, and an auxiliary limit
switch that is calibrated with the fail position. The battery
pack is installed inside of the actuator housing, so a
separate enclosure to house the battery in not required.

When power is received from the primary power source,

it is directed to the actuator motor and switches for
normal cycling of the actuator. When the primary power
source is interrupted, the battery pack is then connected
to the motor and switches, and powers the actuator to
the failsafe position. In this failsafe position, the auxiliary
limit switch is tripped, and can be wired to an alarm. Once
the primary power source is restored, the battery pack is
disconnected and normal operation resumes.

With constant power to terminal #’s 1 & 4 (J1) and the dry contact switch is made, the valve will open. When the
dry contact switch is not made, the valve will close. This task is completed via the supply power and does not affect the
battery pack. When the supply power is interrupted, the valve will travel via battery pack power to its predetermined fail

Series 92 Peaktronics Positioner
The DHC positioner is a high performance, high resolution digital positioner. A simple
three-button control is used to configure ALL parameters that the unit needs for a variety of
applications, and eliminates the need for special meters and/or tools for calibration. As long
as there is supply power, the unit can easily be field calibrated.

This positioner can be calibrated for various command types (such as 4-20 mA, 1-5 VDC, 0-5 VDC,
0-10 VDC or digital) and also the default operation upon loss of command (such as fail open,
fail close, or fail as is). The optional transmitter/auxiliary limit switch module is installed into the
positioner card via plug and socket. This allows a user defined feedback signal of current or
voltage, and provides three SPST relay contacts for open position, closed position and a fault
condition.

and closed), and a fault indicator (loss of power, etc.). These contacts are rated for
1A at 24 VDC / 0.5A at 125 VAC.
Standard Features
• Transmitter/relay plugs directly into DHC-100
positioner card
• Its own terminal strip
• Selectable current (0-20mA), or voltage (0-10 VDC)
