Total Valve Systems’ 6820 TRV relief valve system allows users to open or close a valve at a desired set pressure. The system includes the TRV module, an actuator, and an isolation valve. The modular design of the actuator allows the use of valve features including the actuator tanks and thermal protection plugs. No external power is required for the system. It is independent of system backpressure, and when coupled with a ball valve it offers pigging capability and provides protection from overexposure or shutdown. The system is designed for inline installation between pipe flanges. Each device is a full-face design with pipe flange bolting for lug, water, and short pattern body configurations.
