  • Fluid pressure actuated flow control valve
    Patent number: 5419361
    Abstract: A valve of the type in which a movable valve member is spring loaded to a normally closed position and operated to an open position by a fluid pressure responsive actuator and wherein the valve closing spring and pressure responsive actuator are enclosed in a removable actuator casing. A spring compressing mechanism is provided which is adjustable to a first condition in which a valve closing spring and pressure responsive actuator are allowed to operate the valve member in the normal fashion and to a second condition in which the spring is compressed sufficient to relieve closing pressure on the valve member and enable safe disassembly of the actuator casing and spring.
