Description product group
Accurate metering
Back pressure valves are designed for different applications, and can be adjusted to suit different pressures. They are also used in conjunction with pulsation dampers to generate low-pulsation metering.
Relief valves are used in the bypass to protect pumps, pipes and fittings from overpressure in the event of incorrect operation or blockages, and can be adjusted to suit different pressures. In the event of a malfunction, the pump pumps back into the storage tank.
Multifunction valves have preset back pressure and relief pressures, and connect directly to a pumps discharge valve.
Please refer to the relevant notes for the different designs.
To select the right valve for you, please use the Spare Parts and Accessories Finder. By entering the identity code or the material number of your product, you can easily find suitable spare parts and accessories.
