NOMINAL SIZE 6 MM ISO 4401/CETOP R35H SIZE 3 NFPA DO3 DIN 24340 A6 All ports - corner power 4500 PSI (315 BAR), 5.2 GPM /20 liters per min. Self contained cartridges fitted in bodies with industry standard mounting interface. Bidirectional flow capacity. Bidirectional zero leakage closure. With or without override. ISO 4401 size 3 body, with or without check valve or orifice in pressure port. Special versions with closed crossover switching characteristics for flows up to 10 liters per min. (for accumulator or clamping systems). Coils can be replaced without

disturbing or opening the hydraulic system. DESCRIPTION Series W2... poppet valves are self- contained cartridge units mounted in a body with an industry standard ISO 4401 size 3 manifold-mounting surface. They operate on the proven guided poppet principle and the guide stem requires only one seal. Coils can be replaced or changes to a different voltage and current (AC to DC or vise-versa) while the hydraulic system is pressurized. The 3 way / 2 position (3/2) and 4 way / 3 position (4/3) units can be supplied with poppets having closed crossover switching characteristics. These versions (all ports are isolated during valve change over) ensures no loss of pressure during switching. This is an important benefit in accumulator, low volume and clamping systems.
