Description
SVP-7200 is a high capacity, full nozzle pilot operated safety relief valves designed to guarantee reliable and high quality overpressure protection for air, gas, steam, vapor, liquid and two phase applications.
Modulating and on-off pilots are available. Thanks to the minimum flow through the pilot, guaranteed by the no-flowing design, AST pilot operated safety valves are suitable for cryogenic service.
For an increased flow capacity full bore pilot operated safety valves are available.
Wide range of accessories and exotic materials are available for the pilot operated safety valves type SVP-7200.
Soft seats or metal to metal seats, with superior tightness performance, are available.
Customized solutions with special connections, in accordance with the licensor specification, and high pressure applications that exceed API 526 limits are available
