DESCRIPTION

SPECIFICATIONS

The model RG873V is a Piston type dome-loading
regulator. It utilizes a balanced poppet design for
high flow and minimum effect of inlet pressure on
outlet pressure. The poppet assembly is contained in
a cartridge with internal filtration for easy in field
changing. The regulator is self-venting.

OPERATION

Outlet pressure

RG873V-02

Outlet pressure is adjusted by applying pressure to
the dome port. When reducing the pressure the regulator will self vent via the vent hole near the cap.
This is normal. When reducing set pressure, reduce
pressure to below the new setting then increase pressure to the new setting. Typically a Proportion Air
electro-pneumatic control valve pilots the regulator
with the desired pressure.
