R-Series Proportional Pressure Relief Valves

The R-Series Proportional Relief Valves provide simple and reliable overpressure protection for a wide variety of liquid or gas General Industrial applications with set pressures from 0.7-413 bar (10-6000 psig). These valves gradually open as the pressure increases and close when the system pressure drops below the set pressure.  

The set pressure of the R-Series Pressure Relief Valve can now be adjusted here in Vantaa or on-site.

We can set the overpressure valve opening pressure for R3A, RL3, R4 and RL4 series relief valves at our premises in Vantaa. We can adjust the set pressure with nitrogen for gas systems until a maximum pressure of 103 bar. This enables a faster delivery time rather than those valves adjusted at the Swagelok USA factory.
