HA 5025 Pilot Operated Check Valves VJR2-10/M 2/2005 Sandwich Plates Size 10 pmax up to 350 bar Qmax up to 100 L/min Replaces HA 5025 1/2003 Pilot operated check valve sandwich plate for use in stacking assemblies 3 models - double valve with check valves in lines A and B - single valve with check valve in line A - single valve with check valve in line B Installation dimensions to ISO 4401-05-04-0-94 and DIN 24 340-A10 Functional Description A pilot operated check valve closes tightly the hydraulic springs push the poppets onto the seats and the circuit circuit between the valve and the actuator. The valve between the check valve and the actuator is closed consists of the housing (1), one or two check valves (2), under pressure. (3) and the pilot piston (4). The main poppets of the To ensure that the check valves close tightly, a check valves are provided with pilot poppets (5) which directional valve with functional symbol Y is to be used, enable opening the check valve under pressure. which connects in its middle position the ports A1 and When fluid flows from A1 to A2 it opens the check valve B1 with tank T (see the typical circuit diagram). (2) and at the same time shifts the pilot piston (4) which The valve housing (1) is phosphate coated, the surfaces opens by means of the pilot poppet (5) the check valve of the other parts are zinc coated. (3). When the pressure in channels A1 and B1 drops, the
