KR Hydraulic Pressure Regulators

Pacseal Hydraulics, Inc.

ShearFlo KR PRESSURE REGULATORS


FEATURES


  • ShearFlo® sealing technology ensures high cycle life for critical service applications

    even in contaminated fluids.

  • Hardened stainless steel sealing elements are lapped and polished to exacting standards of

    finish and flatness which produces a leak proof, contaminant resistant

    metal-to-metal seal.

  • The sealing elements are spring preloaded and pressure energized which maintains

    contact between the two sealing surfaces causing continuous lapping during use

    which eliminates small scratches.



OPERATOR OPTIONS


Manual:

Adjustment handle can be threaded in to increase or out to decrease compression on the spring and thus on the regulated outlet pressure.


Failsafe Air or Hydraulic Motor Drive with Manual Override:

This option 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.

 


OPERATION AND SYSTEM INTEGRATION GUIDELINES


1. Flow Capacity:

Consideration must be given to the flow capacity of the interconnect piping between KR Regulators (KR) and the wellhead equipment being operated. Inadequate flow capacity may result in excessive back pressure which can cause the KR to hammer or chatter which is rapid opening and closing as the KR seeks to shutoff at set pressure. Also excessive back pressure will reduce the flow as the KR may not be fully open which will reduce the function time of the equipment being operated.
