Pneumatic Directional Control Valves - Numatics

Directional control valves route compressed air to cylinders and actuators, controlling when and which way they move. They're the core of any pneumatic control circuit.

Valve Types

• 2/2, 3/2, 5/2 and 5/3 valves – match circuit needs
• Solenoid-operated valves – electrical control
• Manual and mechanical valves – lever, button and cam operation
• Manifold-mount valves – compact valve banks
• Fieldbus valve terminals – networked control

Choosing a Valve

Size the valve flow (Cv) to the cylinder bore and speed. Choose function, actuation, voltage and port size. Manifolds simplify plumbing.

Centro supplies directional control valves for pneumatic automation.

Directional control valve parts and kits restore valve performance without full replacement. Seals, spools, solenoid coils and operators wear with use.

Parts Available

• Seal and repair kits – restore sealing
• Solenoid coils – replace failed coils
• Manual operators – overrides and actuators
• Sub-base gaskets – leak-free mounting
• Connectors – DIN and M12 plugs

Ordering Parts

Have the valve model and series ready. Coil voltage and connector type must match.

Regulators used with directional control valves set the pressure going to individual actuators or valve stations. This lets each cylinder run at the force it needs while sharing one air supply.

Regulator Options

• Manifold-mount regulators – sandwich between valve and base
• Inline regulators – adjust pressure at the actuator
• Dual pressure regulators – different pressures for extend and retract
• Gauges and locking knobs – monitor and secure settings

Choosing a Regulator

Match to your valve series and port size, then choose pressure range and flow. Lower pressures save air and reduce wear.

ISO valves follow international standards (ISO 5599) for mounting dimensions, so valves from different manufacturers can be swapped. They're common in industrial automation and machine building.

Features

• Standard mounting interface – interchangeability
• Size 1, 2 and 3 – range of flow capacities
• Sub-base and manifold mounting – flexible installation
• Solenoid and pilot operation – control options

Choosing an ISO Valve

Select size for flow, function (5/2, 5/3) and voltage. ISO valves simplify replacement and spare parts.

Centro supplies ISO valves and sub-bases.

Manifold assembly kits contain everything you need to build a bank of pneumatic directional control valves on a common manifold. Mounting valves together saves space, simplifies air supply and exhaust piping, and makes valve banks easier to service.

What's in a Kit

• Manifold bases and sub-plates – supply air to multiple valve stations
• End plates and seals – close off the manifold and route supply and exhaust
• Tie rods and mounting hardware – hold the assembly together
• Blanking plates – reserve stations for future valves
• Isolation and pressure plugs – create separate pressure zones on one manifold

Ordering Tips

Kits are specific to a valve series, so start with the valve model number and the number of stations you need. Plan for one or two spare stations so the bank can grow later. For electrically wired manifolds, check the connection style: individual wiring, multi-pin or fieldbus.

Centro can help you configure the right manifold kit for your valves and confirm part numbers before you order.

Pneumatic accessories connect, protect and fine-tune compressed air systems. Fittings, tubing, check valves, flow controls and filters may be small parts, but they have a big effect on machine performance, air consumption and reliability.

Pneumatic Accessories

• Pneumatic fittings and tubing – push-to-connect, compression and barbed
• Check and flow control valves – control direction and speed
• In-line filters – point-of-use protection for valves and actuators
• Air volume tanks – supply surges for high-demand cycles
• Air valve switches and relief valves – sensing and overpressure protection

Choosing Accessories

Match tube size and material (polyurethane, nylon, PTFE) to pressure, flexibility and chemical exposure. Use flow controls to set cylinder speed. Fixing small leaks in fittings and tubing is one of the easiest ways to cut compressed air costs.

Centro carries pneumatic accessories to build, maintain and improve air systems.

Seals and repair kits are indispensable for various mechanical systems and equipment maintenance and repair operations. Seals, which come in a wide range of materials and designs, are critical for preventing leaks and maintaining the integrity of hydraulic, pneumatic, and mechanical systems. These seals effectively block the escape of fluids, such as oil or gas, and play a vital role in ensuring system efficiency and longevity. Repair kits are curated collections of replacement parts, including seals, gaskets, O-rings, and other essential components. They are designed to simplify the repair and maintenance process by providing all the necessary parts in one package, facilitating quick and cost-effective fixes. Whether it's a hydraulic system in heavy machinery or a simple household appliance, seals and repair kits are crucial for ensuring the reliability and longevity of mechanical systems by preventing leaks and facilitating efficient repairs.
