A pilot-operated relief valve assembly can include a relief valve, and a pressure detection assembly. A valve lift factor or indicator of relief flow can be determined based on pressure measurements gathered by the pressure detection assembly.

Pilot-operated relief valve assembly

A control valve includes a piston-housing having a hollow portion. The hollow portion has a first end, an open end, first and second internal chambers, and a fluid port configured to allow fluid to exit the second chamber. The first chamber is nearer the first end, and the second chamber is nearer the open end. A piston is located within the housing and is adapted for reciprocal motion. The piston includes a first and second seal-engaging portions. The first seal-engaging portion has a diameter that is less than the diameter of the second seal-engaging portion.

Flow control system and control valve having closure assistance

A surge relief valve includes a piston housing and a piston located within the housing for reciprocal motion. The surge relief valve also includes a position sensor to resolve the axial position of the piston relative to the piston housing. The position sensor includes a sensor body coupled to the piston housing and a movable element configured to move linearly relative to the sensor body and configured to move axially with the piston. At a least portion of the sensor body is located within the piston housing.

Relief valve with position indication

A method and apparatus for calibrating a turbine flow meter via adjustment of electromagnetic sensor position are disclosed herein. In one embodiment, a turbine flow meter includes a flow tube, a plurality of electromagnetic pickups, and a locator plate. The electromagnetic pickups are configured to detect rotation a flow indicator in the flow tube. The pickups are secured to the locator plate. The locator plate is configured to adjustably position the pickups relative to the flow tube.
