FIELD: valving systems.
SUBSTANCE: solenoid-operated valve comprises housing (1) with supplying branch pipe (3), piston type servo drive made of piston (6), hydraulic cylinder (7), spring (13), charging opening (14), and relief opening (15) mounted in guiding pipe (16). The face of pipe (16) is overlapped with sealing disk (28) mounted on the bottom of bushing (17). Bushing (17) is made in face (18) of a hollow conical electromagnetic armature. Housing (19) of the armature is located in the zone of action of magnetic space (26). The space is formed by yoke (23) and central ring member (25). The central ring member together with housing (24) define electromagnetic drive of the valve. Outlet branch pipe (3) of the valve is mounted on the face of housing (24) of the electromagnet. The valve has a manual doubler. The manual doubler is provided with axle (31) with sealing members (32) and member (33) for affecting the armature and handle (34) with spring (35). Member (33) is interposed between the faces.
EFFECT: expanded functional capabilities.
