RZI
Long service life
The compact design of the check valve RZI even makes it possible to operate in very limited spaces. It is robust and long lasting and can also be fitted with soft seals in a metallic seat or strip-metal seals for use at higher temperatures. Based on the same proven design, the check valve RZI was developed for pipe dimensions over 1,000 millimetres. Its damping system has been adapted to suit the greater forces.
The RZN and RZI check valves are ideally suited for protecting pumps for liquid media. Their high flexibility of material and seal models enables the valves to be used in a wide variety of applications. For example, a seawater model is available in stainless steel and with a hard rubber lining.
