Fluid Handling

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Flow-Adjustment Valve Manifolds

Flow-Adjustment Valve Manifolds

Control flow to multiple points from one source

On-Off Valves

Start and stop flow through a line

Orifice Valves

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

Check Valves

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

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

Sampling Valves

Sampling Valves

Drain a small amount of fluid for inspection without disrupting flow

Diverting Valves

Diverting Valves

Redirect flow between ports

Float Valve Bodies

Float Valve Bodies

Pair with floats and rods to create float valves that meet your needs

Vacuum Breakers

Vacuum Breakers

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

Mixing Valves

Blend hot and cold water, steam, or oil to maintain a set outlet temperature and prevent scalding

Pressure-Regulating Valves

Pressure-Regulating Valves

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

Pressure-Relief Valves

Pressure-Relief Valves

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

Tube and Tube Fittings

Tube and Tube Fittings

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

Hose and Hose Fittings

Hose and Hose Fittings

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

Pipe and Pipe Fittings

Pipe and Pipe Fittings

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

Measuring and Inspecting

Calibration Columns

Calibration Columns

Calibrate the flow rate of metering pumps
