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.

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

A pressure relief valve that uses a pilot valve to indirectly activate the main valve.

A pressure relief valve that uses a pilot valve to indirectly activate the main valve.

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.

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 pressure relief valve that is intended to release excess pressure or admit pressure to prevent a vacuum forming when filling or emptying a pipeline or tank.

A pressure relief valve that is intended to release excess pressure or admit pressure to prevent a vacuum forming when filling or emptying a pipeline or tank.

A self operating valve that is set to open at a certain pressure level to prevent the pressure in a container or system from reaching unsafe levels.

A distillation column intended to clean gas by washing the gas flow with water or with another liquid entering at the top of the vessel and sprayed in the gas. Typically to remove dust and small particles.

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.

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 relief valve that is used for pressure compensation purposes by admitting (letting in) a pressure to prevent that vacuum is forming when filling or emptying a system.

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