Series 50 Miniature Regulator Kuhnke System Logic Devices
Sub - Miniature Pressure Regulator
The sub-miniature Series 50 regulator provides regulation of air
pressure from 0 to 115 PSI. Available in both relieving and
non-relieving versions, the unit's size and shape makes it ideally
suited for mounting in dental, medical and laboratory equipment
where close regulation and fine adjustments are necessary.
The regulator is supplied with a panel nut for mounting in a 1/2
inch diameter hole. It can be screw driver adjusted, and set with a
locking nut, or with the use of a control knob can be continuously
adjusted. Ports (2) have 10-32 (M5) threads and are 180° apart
on the side of the regulator body. The housing is nickel plated
brass.
Several adjustment ranges are available for close regulation in
Regulator with most applications. Special designs are available.

The standard regulator is supplied with a slotted shaft
for screwdriver adjustment. A plastic knob catalog

fastening holes and approximate dimensions are 1-
9/16” wide x 1 1/16’ high.
Operation
Relieving type regulators allow excessive pressure on
the secondary side of the regulator to bleed off to the
atmosphere, helping maintain steady pressure. Non-
relieving types are used where pressure build up is not
a concern as in air motors, or air gun applications etc.

Miniature regulators are not intended to be used as primary line regulators.

Manifold Section for Regulators
50800
Aluminum base is used for mounting manifold type
regulators on Kuhnke Series 84 manifold systems to
regulate supply pressure to downstream valves. Base
connects air supply to regulator input. Output sends
lowered air pressure to the manifold valves on the
secondary side. With the addition of a header kit (Cat.
no. 84465), the section can be used as a mounting base
for regulators. See Series 84 valves for details on the
manifold system.
