A detecting instrument that is intended to analyse a substance for its composition and/or properties.

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 valve that can be used to modify (regulate) the fluid flow rate in a process control system. It usually includes an actuator, which responds to a signal from the controlling system and changes the position of the flow controlling element in the valve.

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 valve that has a closing member which is an eccentric rotating disc.

A detector that is intended to sense a flame.

A detector that is intended to sense the presence of a specified concentration of a gas.

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 manual call point is a device which enables personnel to raise an alarm in the event of a fire incident by pressing a frangible element to activate the alarm system.

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

is a facilty for measure & control, including the main plant computerized operational system, where all process, utility and off site activities are monitored. The system may be located in the main control room. (e.g. PLC Programmable logic controller, DCS distributed control system, ENMC Electrical Network Monitoring and Control system).

A manual control switch that is intended to switch when you push or touch the button.

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 detector that is intended to sense smoke.

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.
