PORV are also called pilot-operated safety valve (POSV), pilot-operated pressure relief valve (POPRV), or pilot-operated safety relief valve (POSRV), depending on the manufacturer and the application.

Pressure relief valves (PRVs) can be categorized into two primary groups – conventional spring-operated valves and pilot operated valves (PORVs). This post outlines the basics of their operation, advantages, and disadvantages to consider when evaluating which type may be best suited for an application.

Anderson Greenwood Pilot Operated Pressure Relief Valves (POPRVs) provide advanced, reliable and efficient overpressure protection. With a track record of more than 50 years, the product technology is designed for a wide range of applications, from basic to the most severe service conditions. 2017 Emerson. All Rights Reserved.

Pilot operated pressure relief valves (POSV = “pilot operated safety valves”) are controlled by the process medium in which they operate. To achieve this, system pressure is fed to the pilot valve (= control component for the main valve) via the pressure tapping line.

Consolidated Pilot Operated Safety Relief Valves (POSRVs) offer the safety you expect, the dependability you require, and the efficiency you need to keep your operations running smoothly. These valves offer a premium performance and numerous technical benefits and operating advantages over traditional Pressure Relief Devices.

2024年2月5日 · A pilot-operated safety relief valve is a pressure relief valve in which the major relieving device (main valve) is combined with and is controlled by a self-actuated auxiliary pressure relief valve called a pilot valve.

Introduced in 1968, the Type 93 is a pilot operated pressure relief valve designed with elastomer seats and seals and in a variety of materials to satisfy the majority of gas piping and chemical tank applications and is also suitable for use on marine vapor recovery systems.

To determine which pilot operated safety relief valve type is most appropriate for your application, please use the following guidelines: In the Application Guide (below), note which valve types seem most appropriate for your application.

The replacement of direct spring-operated pressure relief valves (PRVs) with pilot-operated safety relief valves (POSRVs) can help plant operators streamline maintenance processes, reduce maintenance costs, address common valve performance issues, maintain safety and potentially increase output.
