Discover high- and low-pressure proportional relief valves that open gradually as pressure increases. Suitable for liquid or gas service.

Low-pressure RL3 and RL4 series—the spring is already installed. For valves not actuated for a period of time, initial relief pressure may be higher than the set pressure. Technical Data. Outlet Working Pressure . Set Pressure. Outlet pressure should not exceed inlet pressure.

高压和低压比例卸荷阀可随压力的增加而逐渐打开。 适用于液体或气体服务。

Low-Pressure Proportional Relief Valves (RL3 Series and RL4 Series) One spring for the full set pressure range Valves available factory-set to a specified set pressure

Swagelok proportional relief valves should never be used as code safety relief valves. Some system applications require relief valves to meet specific safety codes. The system designer and user must determine when such codes apply and whether these relief valves conform to them. Swagelok proportional relief valves are not "Safety

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.

Swagelok® Relief Valve Setting. We are able to calibrate the RL3 and RL4 series low-pressure relief valves, and R3A and R4 series high-pressure relief valves equipped with the A, B or C spring (to a maximum of 1500 psig). Click here to read more about our relief valve offerings.
