KR-75 PRESSURE REGULATORS

The ShearFlo® KR-75 pressure regulator ensures high cycle life, negligible internal leakage and contaminant resistant operation for 1” piping. Its modular design allows for various operator and porting options with supply pressures to 6000 psi and regulated outlet pressures ranging from 50 psi to 6000 psi.

PacSeal Hydraulics’ pressure regulators have become the industry standard for oil and gas BOP control systems because of their reliability, accuracy and long-life robustness in corrosive and critical service conditions. Maintaining hydraulic system pressure at a set value is vital for all downstream components and functions. Strict inspection and testing requirements and 100% American-made components ensure quality and reliability that cannot be found anywhere else.
