Electronically and hydraulically-actuated drain valve |
摘要 |
A valve for a fluid circuit is disclosed. The valve has a main valve element with a first end and a second end. The main valve element is movable between a flow-passing and a flow-blocking position in response to fluid pressure exerted on the first and second ends. The valve also has a solenoid mechanism operatively associated with the main valve element to move the main valve element toward one of the flow-passing and the flow-blocking positions. The valve further has a main valve spring configured to bias the main valve element in opposition to movement caused by the solenoid mechanism. The valve additionally has a relief valve element configured to communicate a fluid with the first end of the main valve element in response to a fluid pressure to initiate movement of the main valve element. |
