GKV51PR Regulator Control Valve

GKV51PR Regulator Control Valve

The Regulator Control Valve GKV51PR can automatically reduce the high inlet pressure to a stable low outlet pressure, regardless of changes in flow rate or inlet pressure. It uses a precise pressure regulator to maintain the outlet pressure within a pre-set range. When the outlet pressure exceeds the setting pressure of the relief valve, the valve body and the regulator will automatically close, creating a tight seal. If the optional check feature is selected, the valve will close when reverse pressure is generated, preventing the return of liquid by allowing the return liquid to enter the chamber and trigger the closure.

Testing Standard

API 598, EN-12266-1

All valve stems and seats are tested to 100 psi gas closure test for

bubble tight integrity before shipping, Vacuum Service to 29" Hg

The GEKO Regulator Control Valve GKV51PR is designed to provide automatic

pressure reduction from high inlet pressure to a stable low outlet pressure,

regardless of changes in flow rate or inlet pressure. It features a precise

pressure regulator that keeps the outlet pressure within a pre-set range. If the

outlet pressure exceeds the set pressure of the relief valve, the valve body and

regulator will automatically close, ensuring a tight seal. For systems requiring

the prevention of reverse flow, an optional check feature is available, which

causes the valve to close when reverse pressure is generated, blocking the

return of liquid.

 

Product Features

Sensitive and Precise Pressure Control: Maintains consistent and stable outlet pressure even with changes in flow rate or inlet pressure. 

Easy to Adjust and Maintain: The valve is simple to adjust and requires minimal maintenance, making it convenient for long-term use.

Excellent Sealing Performance: Provides reliable sealing, preventing leakage and ensuring high efficiency during operation.

Built-in Filter Device: Helps prevent clogging, keeping the system clean and improving its overall performance and longevity.

Optional Check Valve Feature: Prevents the return of liquid when reverse pressure occurs, ensuring system safety.

 

The GKV51PR valve is ideal for water treatment, chemical processing, and other industrial applications where reliable pressure control is essential.
