Fluid Handling

Orifice Valves

Restrict the flow of liquids and gases to precisely control rate and pressure

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Flow-Regulating Valves

Flow-Regulating Valves

Maintain the set flow rate of fluid through your system

Check Valves

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

On-Off Valves

Start and stop flow 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

Diverting Valves

Diverting Valves

Redirect flow between ports

Tap Valves

Pierce copper tubing for a secondary line to humidifiers and ice makers; also known as saddle valves

Flow Switches

Turn equipment on or off when flow rate reaches a set point

Sampling Valves

Sampling Valves

Drain a small amount of fluid for inspection without disrupting flow

Vacuum Breakers

Vacuum Breakers

When pressure drops, vents open to prevent suction from drawing liquid back upstream

Air Valves

Fill tanks, tires, and other pressurized equipment

Valve Union Fittings

Valve Union Fittings

Mating parts join valves to a line for quick connection and removal

Directional Control Valves

Directional Control Valves

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

Valve Actuators

Valve Actuators

Automatically start and stop flow to your valve

Pilot Valves

Control air supply to the actuator in other valves

Valve Repair Kits

Valve Repair Kits

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

Drain Valves

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

Air Pulse Valves

Air Pulse Valves

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

Tube Fittings

Make threaded, push to connect, barbed, and other types of connections between lengths of tube

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility

Hose and Hose Fittings

Hose and Hose Fittings

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

Pressure-Regulating Valves

Pressure-Regulating Valves

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

Compressed Gas Valves

Compressed Gas Valves

Check and adjust the pressure of compressed gas in tanks; also known as Schrader valves

Mufflers

Reduce noise and filter exhaust fumes

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

Hydraulic Flow-Adjustment Valves

Hydraulic Flow-Adjustment Valves

Turn the knob to gradually adjust the flow of hydraulic fluid

Hydraulic Check Valves

Hydraulic Check Valves

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

Air Flow Check Valves

Air Flow Check Valves

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

Lubricating

Oil-Dispensing Pump Metering Valves

Oil-Dispensing Pump Metering Valves

Add to manual and electric pumps to dispense the right amount of oil to different lubrication points

Facility and Grounds Maintenance

Faucet Pedals

Start and stop water with your foot or knee to keep your hands free

Water Hammer Arresters

Water Hammer Arresters

Absorb shock of sudden shutoffs to prevent knocking noises in water pipes
