USVR 1" pressure relief valve
Adjustable to 7 positions
For systems with thermostatic or zone valves
Description
The pressure relief valve is used to protect heating systems equipped with automatic or manual control devices, such as thermostatic valves or two-way zone valves, which can cause overpressure in the closed circuit, to maintain the hydraulic balance and safety of the system.
With the 7-position adjustment mechanism it allows you to adapt the valve response to the specific needs of the system: Position “0” = Fully open - Position “7” = Close to closing Δp = 0.5 bar.
