A2 Introduction
This repair manual contains information for the PO, PC,
PC, High Pressure Control Valve.
A3 Description
The Kimray High Pressure Control Valve (HPCV) is
designed for use in liquid and gas control applications
which require modulating (throttling) or on/off service.
The HPCV has a single port Body and a pneumatic spring
actuator. This actuator is available in either pressure
open PO (normally closed), or pressure closing actuators.
Because of the high pressure range, a Packing Box
houses a non adjustable spring loaded teflon sleeve
around the Stem with a Felt Wiper and Buna Back Ups for
leak free sealing.
CAUTION:
When ordered, the HPCV configuration and construction
materials were selected to meet specific pressure,
temperature, pressure drop and fluid conditions. Since
some Body / trim material combinations are limited in their
pressure drop and temperature ranges, do not subject
the pressure regulator to any other conditions without
first contacting the Kimray Inc, sales office or a sales /
applications representative.
Kimray reserves the right to modify or improve the designs or specifications of such products at any time without notice.
