The MAR-1C is a non-relieving miniature pressure regulator with a #10-32 female inlet and outlet, designed for air, water, or oil, with a maximum input pressure of 300 psig and air flow of 3 scfm at 50 psig or 5 scfm at 100 psig. It operates from 32 to 230°F, features a brass body with nitrile seals and a stainless steel stem and spring, and uses a plastic knob for adjustment with a 40-pitch thread. The plunger-style adjustment increases output pressure proportionally to plunger travel and exhausts output pressure to atmosphere when released, with 7/32 inch plunger travel. It is mounted via #15/32-32 thread with nuts and lockwashers included. The pressure range is 10 to 30 psig.
When Clippard introduced a miniature regulator in 1962, the MAR-1 became very popular as a simple, robust, and cost-effective regulator in a small pack- age with exceptionally long life . As regulator applications continue to increase, Clippard is meeting the demand with a variety of new models, options and improvements.
Regulators are offered in either relieving or non-relieving versions. The relieving design maintains a constant pressure output even when downstream conditions change, while non-relieving regulators do not automatically compensate for changes in downstream flow or pressure. There is no vent to atmosphere, as in a relieving type regulator, and the output pressure can increase due to a downstream event. Non-relieving versions can accommodate compatible liquid applications.
Medium: Air, Water* or Oil*
Input Pressure: 300 psig max.
Air Flow: 3 scfm @ 50 psig; 5 scfm @ 100 psig
Temperature Range: 32 to 230°F
Mounting: #15/32-32 thread. Nuts and lock washers furnished
Materials: Brass body, Nitrile seals (FKM optional “-V”), stainless steel stem and spring
Adjustment: By means of a knob with micro-adjustment (40 pitch thread). Screwdriver slot and plastic adjust- ment versions also available.
1C and 1CP Models: As plunger is depressed, pressure increases proportionally to the travel; when plunger is released the input is closed and the output pressure is exhausted to atmosphere. 7/32” plunger travel.
