Boolean
Is a a valve where the flow follows a radial annulus around the axial seat and spring case, passing straight through the valve with very little deviation
A ball 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 butterfly 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 choke 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 pinch 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 diaphragm 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 control valve that is a gate valve and an actuated valve.
A control valve that is a globe valve and an actuated valve.
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 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.
A control valve that is also a plug valve and an actuated valve.
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.
