n: on a mud pump, the valve that opens to allow mud to be pushed out of the pump (discharged) by the pistons moving in the liners.

n: the valve used to control the up/down of drill fluid

n: in tank sampling, a sample obtained from the draw-off or discharge valve.

n: any device used to control the liquid level in a tank by actuating electric or pneumatic switches that open and close the discharge valve or the intake valve, thus maintaining the liquid at the desired level.

n: any of the valves on a reciprocating pump (such as suction and discharge valves) or on a sucker rod pump (such as a ball-and-seat valve).

n: feed valve and drainage valve of reciprocal pump.

n: a type of compressor that has pistons moving back and forth in cylinders, suction valves, and discharge valves, i.e., a positivedisplacement compressor. Reciprocating compressors are used extensively in the transmission of natural gas through pipelines.

n: a pump consisting of a piston that moves back and forth or up and down in a cylinder. The cylinder is equipped with inlet (suction) and outlet (discharge) valves. On the intake stroke, the suction valves are opened, and fluid is drawn into the cylinder. On the discharge stroke, the suction valves close, the discharge valves open, and fluid is forced out of the cylinder.

n: A type of fluid pump in which reciprocating pistons or plungers displace the fluid.

a piston pump.
