Fluid Handling

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Orifice Valves

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

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

Flow Switches

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

Air Valves

Fill tanks, tires, and other pressurized equipment

Vacuum Breakers

Vacuum Breakers

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

Valve Union Fittings

Valve Union Fittings

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

Sampling Valves

Sampling Valves

Drain a small amount of fluid for inspection without disrupting flow

Diverting Valves

Diverting Valves

Redirect flow between ports

Flowmeters

Measure the flow rate of a liquid or gas

Flow Transmitters

Flow Transmitters

Send flow rate measurements to PLCs, data loggers, and remote displays

Mufflers

Reduce noise and filter exhaust fumes

Tube Fittings

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

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

Pipe and Pipe Fittings

Pipe and Pipe Fittings

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

Compressed Gas Valves

Compressed Gas Valves

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

Measuring and Inspecting

Calibration Columns

Calibration Columns

Calibrate the flow rate of metering pumps
