Fluid Handling

Directional Control Valves

Directional Control Valves

Manage the flow of fluids to move equipment in air- and hydraulic-powered systems

Manual On/Off Valves

Manual On/Off Valves

Start and stop flow through a line

Check Valves

Permit flow in only one direction by closing when flow stops or reverses

Valve Actuators

Valve Actuators

Automatically start and stop flow to your valve

Air-Actuated On/Off Valves

Air-Actuated On/Off Valves

Operate on compressed air to start and stop flow faster than motor-driven valves

Diverting Valves

Diverting Valves

Redirect flow between ports

Solenoid On/Off Valves

Solenoid On/Off Valves

A solenoid withstands rapid cycling for applications with frequent opening and closing

Flow-Adjustment Valves

Flow-Adjustment Valves

Gradually open and close to control the volume of air and liquids through a line

Air-Exhaust Valves

Air-Exhaust Valves

Vent or divert exhaust to speed up the operation of air cylinders, actuators, and other equipment

Pilot Valves

Control air supply to the actuator in other valves

Valve Bodies

Attach to actuators to automatically or manually control flow in your line

Air Valves

Fill tanks, tires, and other pressurized equipment

Drain Valves

Vent air or discharge liquids to remove excess fluid from your system

Solenoid Coils

Replace the coil that actuates your flow-control valve

Valve Repair Kits

Valve Repair Kits

Maintain valves with replacement parts such as seals, plungers, and springs

Air Pulse Valves

Air Pulse Valves

Convert continuous flow into bursts that reduce air consumption in dryers and dust collectors

Motor-Actuated On/Off Valves

Motor-Actuated On/Off Valves

An electric motor handles higher flow rates and pressures than solenoid valves

Air Chucks

Connect air hose to Schrader valves, which are common on tires and hydraulic systems

Pipe and Fittings

Pipe and Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases

Power Transmission

Air Flow Control Valves

Air Flow Control Valves

Control the speed of air-powered equipment by adjusting the volume of airflow entering or exiting

Air Flow Check Valves

Air Flow Check Valves

Open to allow air flow in one direction and close when flow stops or reverses

Air Cylinders

Push and pull loads to do everything from stamping materials to sorting parts on conveyors

Compressed Air Dryers

Compressed Air Dryers

Remove lingering moisture from air lines
