Abstract
A fluid control valve actuated by differential pressure across a diaphragm member. The diaphragm member is secured to a piston mounted thereon with a seal ring. The seal ring is in fluid-tight sliding engagement with a casing having an inlet port and an outlet port, but is brought into disengagement from the casing upon movement of the piston due to differential pressure across the diaphragm member. Thus, communication between the inlet and the outlet ports may be accomplished.
