Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices

Flow computers, totalizers, and rate indicators integrate the functions of flow and temperature measurement, computation, data acquisition, input / output (I/O) standardization, and closed loop control. They require external sensor inputs and may be used as local rate indicators

Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers. They may be single-acting (with a spring return) or double-acting

Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system

Solids flow meters measure the flow rate of bulk solids, powders, grain, etc

Linear thrusters use double-acting pneumatic, hydraulic, or electrohydraulic cylinders mated to plates and shafts to provide cyclical linear motion. They are used in conveying, positioning and inspection systems

Pneumatic relays and volume boosters control output air flow and pressure in response to a pneumatic input signal. They can perform simple functions such as boosting or scaling the output, or use complex reversal, biasing, and math function operators

Electro-pneumatic transducers convert current or voltage input signals to proportional output pressures. They are used as process control elements in valves, pneumatic relays, and flow regulators for applications such as spray and damper control

Tubing is used to transport fluid and gas in pneumatic, hydraulic, or process applications. Tubing differs from pipe in that tubing's outside diameter or size is controlled and used for product designation

Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion

Air compressors are machines that compress air to higher than atmospheric pressures for delivery to pneumatic or robotic tools, industrial equipment, or direct-use applications

Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves

Hydraulic and pneumatic testing services test and evaluate hydraulic and pneumatic components and finished products through flow and pressure, performance, environmental exposure, dynamic, and other specialized tests

Manifolds and manifold systems are fluid-distribution devices. They range from simple supply chambers with several outlets to multi-chambered flow control units including integral valves and interfaces to electronic networks

Flow orifices and flow restrictors contain precision-machined holes and filters or screens to restrict flow and reduce pressure. They are available as stand-alone devices and in kits, assemblies, restrictors, and restrictor valves
