Fluid Handling

On-Off Valves

Start and stop flow through a line

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Diverting Valves

Diverting Valves

Redirect flow between ports

Check Valves

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

Valve Bodies

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

Orifice Valves

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

Tap Valves

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

Drain Valves

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

Vacuum Breakers

Vacuum Breakers

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

Backflow-Prevention Valves

Backflow-Prevention Valves

Dual checks stop flow from reversing and contaminating your system

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

Vacuum-Regulating Valves

Vacuum-Regulating Valves

Control the amount of air that a vacuum pump draws from your system to maintain vacuum levels

Vacuum-Relief Valves

Vacuum-Relief Valves

Open at a set vacuum and close when the vacuum level drops to protect equipment

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Manifolds

Distribute air or fluid to multiple places from a single source; also called headers

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

Junction Blocks

Junction Blocks

Organize and separate multiple lines in a pipe system; air and fluid flow through the threaded holes

Mufflers

Reduce noise and filter exhaust fumes

Lubricating

Coolant Dispenser Hose and Fittings

Coolant Dispenser Hose and Fittings

Snap together and position to deliver coolant, oil, water, or air in any direction

Facility and Grounds Maintenance

Air Admittance Valves

Air Admittance Valves

Allow air into drain, waste, and vent systems so you don't have to vent plumbing to the outdoors

Building and Machinery Hardware

T-Slotted Framing and Fittings

T-Slotted Framing and Fittings

The most versatile system, attach fittings along the continuous slots to build virtually anything
