Total Valve's 6820 TRV is the most accurate set pressure system in the industry with tight tolerances for any valve size.
This patented system includes the TRV module, an actuator and an isolation valve, typically a triple offset butterfly valve.
With an adjustable set pressure, this system allows the user to operate within 97% of the valve's desired set pressure and the relief capacity is much greater than typical relief systems on the market - allowing for lower overall system costs.
The 6820 is the perfect alternative for buckling pin valves, shear pin valves or rupture pin valves
