Performance Details sage from port 1 to 2: the cartridge has a fully guided check which Note: The performance chart illustrates flow handling capacity for significant spring bias options. p/Q curves are recorded at TOil = 40°C and 46 cSt is spring-biased closed until sufficient pressure is applied at port 1 to open to 2. The flow is blocked in the opposite direction (2 to 1). Flow (l/min) Technical Features All external surfaces are zinc plated and cor- Ordering Code rosion-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 used hybrid cavity Specifications may change without notice.
