A valve includes an inlet and an outlet; a body including a first seat and a second seat; a cavity in the body; a piston positioned in the cavity; and a pilot ball adjacent the piston and that is disposed in a pilot seat, and a rear surface of the piston butts against the pilot seat at a maximum open position of the piston. Each of the first seat and the second seat is a seat that is a mechanical stop that prevents the piston from extending further than the closed position. The piston includes a flat front face that contacts the first seat when in the closed position, and a nose extension that extends outward and away from a center portion of the front face, and the nose extension has an opening through a center of a front surface thereof.

Zero leak pilot operated valve having two seats

A valve includes an inlet and an outlet, a body including a first seat and a second seat, wherein the first seat and second seat are spaced apart from each other at a predetermined distance, a cavity in the body, a piston positioned in the cavity, wherein the piston rests against the first seat and the second seat when in the closed position, and a pilot ball adjacent the piston.

A gas supply system includes a receiver assembly, a gas storage vessel coupled to the receiver assembly, a main poppet positioned at an end of the gas storage vessel and sealing the gas storage vessel when the main poppet is closed, a pilot poppet positioned in the main poppet and sealing the gas storage vessel when the pilot poppet is closed, and a chamber positioned behind the main poppet, wherein when the pilot poppet opens, gas from the gas storage vessel is released into the chamber to exert pressure on the main poppet to open the main poppet.

Gas supply system for pneumatic store ejection utilizing a removable, replaceable and on-board rechargeable gas storage vessel

A valve includes a body, a cavity in the body, and a check valve formed in the cavity. The check valve includes a poppet having a first end and a second end, and a first seat and a second seat, wherein the first seat is formed at the first end, the second seat is formed at the second end, and a diameter of the second seat is greater than a diameter of the first seat.
