    Abstract: A pilot operated relief valve for use on medium and high pressure vessels, conduits, and the like A unique two-stage, non-flowing pilot valve (5) operates a main relief valve (7) of substantially greater capacity. In a preferred embodiment the main valve is mounted directly onto the pressure vessel which is to be vented at a predetermined pressure. The pilot is preferably mounted closely adjacent to the main valve for operating communication therewith. A particularly unique ball (16) selector (24, 15, 76) provides means for testing first and second stages without operating the main valve, providing improved set point and reset or blow-down adjustments for the overall combination.

    Abstract: An intrinsically safe hydraulic valve including a first stage in the form of pilot valves and a second stage in the form of a poppet valve assembly. The poppet valve assembly includes first and second pairs of piston operated poppets which, when selectively operated, control the drive direction of a fluid motor. The pilot valves are electrically controlled through an electromagnet arrangement wherein the valves are closed when the electromagnet is de-energized and opened when it is energized. When the pilot valves are selectively opened, they apply a pilot pressure to one or the other of the pairs of piston operated poppets to drive the fluid motor.

    Abstract: The pilot operated relief valve includes first and second pilot stages (10, 41) and a balanced amin relief valve. A valve body contains the stages and includes two inlet (11, 12) exhaust (13) and test (14) ports. A first stage poppet (18) co-acts with a first seat below stage plunger (48) has upper product pressure. A second stage plunger (48) has upper and lower ends and co-acts with second and third seats for first and second plunger positions. The first seat and inlet port (11) are in communication as the first seat and upper plunger end, and the inlet port (11) and second seat for a first plunger position. Inlet port (12), exhaust port (13) and the third seat are in communication for a second plunger position. Product pressure, exceeding the predetermined value, moves the poppet (18) from the first to the second position and the plunger moves to the second position thereby isolating inlet port (11) to prevent further product flow through the first seat. Flow is then initiated through inlet (12) and exhaust (13) to operate the main valve.
