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.

An actuator that is intended to be operated by pneumatic power.

A mechanical controller that is using pneumatic components to execute its function.

A conveyor for transporting dry, free flowing, granular material in suspension within a pipe or duct by means of a high-velocity airstream or by the energy of expanding compressed air within a comparatively dense column of fluidized or aerated material.

A cylinder where the piston is actuated by compressed air.

A motor that is driven by compressed gas. Typically air.

A pilot switch the actuating system of which is operated by a moving part of a machine, when this part reaches a predetermined position.

A transmitter that is producing a standardized output signal dependent of a received input signal from a position detector.

A handheld or fixed device designed to identify and record the location of an object on the earth's surface. GPS, GALILEO, SYLEDIS, HYPERFIX, LORAN-C, DECCA etc. are all brands and working on different networks.

Elements like impellers rotating by the pressure of the fluid in a closed conduit to measure the flow of a liquid.

A flow transmitter specially designed to convert the signal from a positive displacement flow meter into a standardized electrical output signal.

An analysing instrument intended to determine the pour point of a fluid, i.e. the lowest temperature at which an oil or other liquid will pour under given conditions.

An electric cable intended for transmission of electric power.

A device that removes voltage spikes from an AC or DC electrical supply.

A physical object intended to supply electric power according to specified levels and tolerances.

A detecting element intended to sense pressure.

A gauge intended to measure and display a representation of a measured pressure.

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

A gas flow damper that is used to relieve built-up pressure in a duct system to prevent damage to HVAC equipment.

A fluid regulator that relieves pressure from an enclosed space when the pressure reaches a predetermined value.

A functional switch that (usually) turns an electrical circuit on or off when the pressure level reaches a pre-set value.

A signal converter that is intended to convert a pressure input signal to DC output signal.

A transmitter that is producing a standardized output signal dependent of a received input signal from a pressure element.

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 non-corrugated plate heat exchanger that has flat plates with chemically etched flow passages which are diffusion bonded together into blocks.
