Main device. The CVZ0.S08 allows flow Performance Details passage from port 2 to 1: the cartridge has a fully guided check which ficient pressure is applied at port 2 to open to 1. The flow is blocked in the opposite direction (1 to 2). Technical Features All external surfaces are zinc plated and Note: The performance chart illustrates flow handling capacity. p/Q curves are recorded at TOil = 40°C and 46 cSt is spring-biased closed until suf- Flow (l/min) Ordering Code corrosion-proof. All valve parts are made of high strength steel. Poppet is hardened and ground to guarantee minimal wear and to extend service life. Compact size. Optional bias springs for back-pressure application flexibility. Industry common cavity. Specifications may change without notice.
