Pilot Operated Safety Relief Valve-201

Technical Specification

Size 1″ x 2″ to 8″ x 10″
Body C.I./C.S./CF8/CF8M/Alloy Steel
Trim C.S./Alloy Steel
Minimum Pressure 20 PSI
Maximum Pressure 20 PSI
Maximum Pressure 3000 PSI
Temperature 200 C

Operating Advantage :

1. Bubble-tight closer to set pressure : Series 201 valves operate bubble tight at higher pressure to set pressure ratios, allowing operators to run very close to the system’s maximum allowable working pressure. While protecting the system from over pressure, series 201 allows maximum product through put, increased system profitability and reduced fugitive emissions.

2. Set pressure and blowdown set at pilot control valve : In line service, settings and blowdown adjustments are completed quickly and easily without main valve intrusion. Subsequent reduction in product loss and fugitive emissions add to system profitability.

3. Typical application : The PSV 201 series pilot operated valves are built in conformance to section VIII of the ASME boiler and pressure vessel code for air, gas, vapor and liquid service.

Pilot Operated Safety Valve-810
