Consolidated Pilot-Operated Safety Relief Valves

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.

Features & Benefits

Pilot Operated Safety Relief Valves are designed with several features that differentiate it from traditional spring loaded safety relief valves with superior performance, and with a compact design are lighter weight and easier to install in most applications.

Zero Leakage at High Operating Pressure

Spring Valve

Consolidated Pilot Valves offer industry leading performance with both main valve and pilot seat tightness up to 98% of set pressure. This advanced design ensures zero-leakage during normal operating conditions for even the most demanding high-pressure applications.

Stable & Efficient Overpressure Cycle

Remote sense configuration eliminates rapid cycling valve chatter in applications with >3% inlet line loss, enabling Consolidated POSRVs to open and relieve pressure in a stable and efficient manner.  The modulating style opens proportionally to your overpressure pilot, ensuring a smooth opening cycle and relieving only required capacity, keeping your operation safe, efficient and reliable.

Flexible & Modular Design

Certified on gas, liquid and steam, and configured to suit your application with flexible features including an adjustable blowdown,  bolt-on modulator, pilot line pressure surge snubber and dozens of optional accessories, ConsolidatedPOSRVs can be configured for any service.
