ShearFlo® KR PRESSURE REGULATORS

PacSeal® KR pressure reducing and regulating valves are used to maintain system pressure to a desired value which is below that of the inlet supply pressure.

Model GPM Cv Inlet Port, NPT Outlet Port, NPT
KR-12 2 .23 ½" ½"
KR-38 15 1.84 ½" ½"
KR-75 75 9.4 1" 1"
KR-100 75 9.4 1" (x 2) 1 ½"
KR-140 150 14.9 1" (x 2) 1 ½"
KR-150 190 21 1" (x 2) 1 ½"


The operator provides a control force to the regulator valve piston which balances the hydraulic load inside the valve.

Linear operation causes the ShearFlo® sealing elements to open and close supply pressure and vent ports until the control forces come into equilibrium.

FEATURES

OPERATOR OPTIONS

Manual:

Adjustment handle can be threaded in or out to increase or decrease compression on the spring.

Failsafe Air or Hydraulic Motor Drive with Manual Override:

This pressure reducing valve provides remote operation with a manual override. Upon loss of pilot signal, there is no loss of regulated outlet pressure.

Hydraulic Pilot:

A remote, variable hydraulic signal operates on a piston with a 1:1 ratio which allows for the most precisely controlled outlet pressures of all options. A safety concern, loss of hydraulic pilot pressure will result in the outlet venting to tank.

Air Diaphragm:

A remote, variable air signal operates on a rubber diaphragm to regulate outlet pressure. A safety concern, loss of air pilot pressure will result in the outlet venting to tank.
