Electrohydraulic fluid control valve with high flow rate has control element with solenoid coil and armature for moving closure part from first valve seat to second valve against spring force

摘要

The valve has a tubular body with inlet and working openings communicating transversely via a bore, valve seats between inlet/working openings and between working/outlet openings, a closure part moving between valve seats, a biasing spring and a control element with a solenoid coil and armature for moving the part to the second seat. Rated pressure in the inlet opening exerts a total force on the closure part essentially opposing the spring force. The device has a tubular valve body (22) with inlet and working openings communicating transversely via a longitudinal bore (24) and valve seats between the inlet (23) and working (25) openings and between the working opening and an outlet opening, a closure part (28) moving between the valve seats, a spring biasing the closure part to the first seat and a control element with a solenoid coil and an armature for moving the part to the second seat. The rated pressure in the inlet opening exerts a total force on the closure part essentially opposing the spring force.
