SPOOL VALVE
摘要:
A three position digitally latched fluid control valve (10). The control valve (10) includes a housing (12) which has a cylinder port (16), a supply port (18), and a return port (14). The control valve (10) also contains an internal valve (20) that moves between a first position, a second position, and a neutral position. In the first position, the internal valve (20) provides fluid communication between the cylinder port (16) and the supply port (18). In the second position, the valve (20) provides fluid communication between the cylinder port (16) and the return port (14). In the neutral position, the valve (20) prevents fluid communication between the ports. The control valve (10) has a first actuator (36) and a second actuator (38) that are actuated by digital pulses to move the internal valve (20) between the first, second, and neutral positions.
