Equipment
Equipment that requires this property.

A valve not designed to regulate flow (e.g. on/off). A valve with multiple orifices or flow-restriction device to control fluid flow. Includes an actuator that needs auxiliary power to operate.

A valve not designed to regulate flow (e.g. on/off). A multi port valve which has the possibility of multiple distinct paths for flow through it. Includes an actuator that needs auxiliary power to operate.

A valve that has three or more ports arranged to switch flow.

A needle valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

tag class

A globe valve that has a closure member with the shape of a conical plug (needle) which closes into a small seat.

A lift check valve that has a free gravity or spring loaded piston type closure member.

A control valve that is also a plug valve and an actuated valve.

tag class

A rotary valve that has a quarter turn action in which the closure member is a cylindrical or tapered plug which operates by rotating on its axis and sealing against a downstream seat.

A regulator that is controlling/regulating the pressure in a system.

A valve that includes a means of operation (e.g. spring / gravity / fluid pressure / counter balance), and is not depending on an external source of energy.

A slide valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

tag class

A valve that opens and closes a passageway by sliding over a port.

A valve that has linear action which is fitted with a solenoid for quick operation.

A check valve that is a check valve where the closure member is a disc which swings freely on a hinge and which opens automatically when flow is established and closes automatically when flow ceases or is reversed.

A regulator that is intended to keep a temperature within certain boundaries.

A wafer pattern valve that is a check valve with a wafer pattern valve body.
