Integrated Hydraulics has introduced its new Poppet type two-port, two-way directional control valves for 160ltrs/min systems. The Poppet valve uses a piston pressed against its seat by fluid pressure to prevent flow: with mating parts concentric and surface finish suitable, flow past the valve will be minimal, in this case less than 5 drops/min at 210bar pressure differential. These new valves are suitable for flows to 160ltrs/min and pressures to 210bar in both Normally open and Normally closed versions. The solenoid operates a small pilot piston in the main poppet, this controls the pressure of fluid behind the main poppet and the balance of pressure forces moves the piston to the desired position. Integrated Hydraulics offers 12 and 24V DC and 110 and 220V AC solenoids with a number of industry standard connectors. The coil stem is sealed to prevent corrosion and the coils are the same as those used on other S5 series valves.
