Disclosed is a plug and seal assembly comprising an annular seat ring and a plug head for use in a fluid control valve utilized for regulating a flow of high-pressure fluid. The seat ring includes first, second, and third sealing discs alternately stacked with respective first, second and third resilient bearing discs. The inner annular edges of the first, second and third sealing and bearing discs collectively define a conical sealing surface. The plug head defines stepped first, second and third ramps, each ramp having a truncated conical shape of equal half-angle with the conical sealing surface half-angle being larger than the ramp half-angle. The direct engagement of the first, second and third ramps against respective ones of the sealing discs acts to deform the respective ones of the bearing discs to create three fluid-tight seals therebetween to reduce the risk of leakage of the valve when in a closed position.

Plug and seal assembly

Disclosed is a piston positioning system for positioning a piston within a cylinder of a pneumatic circuit. The system comprises a piston position indicator for sensing an actual piston position, a controller for generating an output signal in response to the piston position signal, a pneumatic valving device for regulating the flow of pneumatic fluid and a solenoid valve configured to energize the pneumatic valving device. The pneumatic valving device comprises a four-way valve, a servo valve coupled to a stepper motor, and a two-way valve. The reversible stepper motor is incrementally rotatable over a desired angle of rotation in proportion to the magnitude of the output signal for linearly translating the servo valve such that the flow of pneumatic fluid maybe manipulated into and out of first and second ends of the cylinder to control the piston position therewithin.

Pneumatic actuator circuit

Disclosed is a blowdown valve for a boiler system for removing fluid that contains debris. The blowdown valve comprises a housing for a shutoff valve and a reversible throttle valve. The shutoff valve is fluidly connected to a fluid inlet that, in turn, is connected to the boiler system. Each one of the shutoff and throttle valves includes a rotatable valve ball having a bore formed therethrough. Rotation of the valve ball alternately blocks and unblocks fluid flowing therethrough. The throttle valve bore includes first and second bore ends. A bore insert is disposed within the bore between first and second debris zones. The bore insert includes passages configured for reducing fluid energy. The first and second debris zones entrap debris therewithin. The throttle valve reverses positions of the first and second debris zones such that entrapped debris may be flushed out of the fluid outlet.
