Fluid Handling

Directional Control Valves

Directional Control Valves

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

On-Off Valves

Start and stop flow through a line

Flow-Regulating Valves

Flow-Regulating Valves

Maintain the set flow rate of fluid through your system

Valve Mounts

Match standard NFPA mounting patterns to connect valves with multiple ports

Valve Manifolds

Valve Manifolds

Control flow to multiple points from one source

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Air Valves

Fill tanks, tires, and other pressurized equipment

Valve Seats

Seal valves when they're closed to prevent leaks

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Hose

Flexible and stronger than tubing; often used to convey liquids and gases under pressure

Air Chucks

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

Power Transmission

Hydraulic Flow-Adjustment Valves

Hydraulic Flow-Adjustment Valves

Turn the knob to gradually adjust the flow of hydraulic fluid
