Fluid Handling

Manual On/Off Valves

Manual 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

Air-Actuated On/Off Valves

Air-Actuated On/Off Valves

Operate on compressed air to start and stop flow faster than motor-driven valves

Solenoid On/Off Valves

Solenoid On/Off Valves

A solenoid withstands rapid cycling for applications with frequent opening and closing

Motor-Actuated On/Off Valves

Motor-Actuated On/Off Valves

An electric motor handles higher flow rates and pressures than solenoid valves

Valve Union Fittings

Valve Union Fittings

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

Valve Repair Kits

Valve Repair Kits

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

Sump Pump Backflow-Prevention Valves

Sump Pump Backflow-Prevention Valves

Block dirty water from returning to your sump pump

Float Valves

Open or close a pipe connection when liquids in a container reach a set level; also known as ballcocks

Float Valve Bodies

Float Valve Bodies

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

Orifice Valves

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

Backflow-Prevention Valves

Backflow-Prevention Valves

Dual checks stop flow from reversing and contaminating your system

Vacuum Breakers

Vacuum Breakers

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

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

Pressure-Relief Discs

Pressure-Relief Discs

Rupture at a set pressure or temperature to vent fluid and gas and protect machinery; one-time use

Vacuum-Regulating Valves

Vacuum-Regulating Valves

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

Hose Fittings

Create threaded, barbed, quick-disconnect, and other types of connections between lengths of hose

Hose Nozzles

Control flow while dispensing water, fuel, hydraulic fluid, coolant, and chemicals

Flame Arresters

Flame Arresters

Absorb heat from a fire in your gas pipeline to stop it from traveling back to the gas source

Mixing Valves

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

Tank Mixing Nozzles

Tank Mixing Nozzles

Circulate liquid in tanks to keep solids from settling

Gas Mixers

Supply controlled amounts of air and gas to burners

Strainers

Install next to valves and pumps to catch debris in your line

Steam Traps

Extract condensation from lines without losing any steam

Power Transmission

Hydraulic On/Off Valves

Hydraulic On/Off Valves

Control the flow in high-pressure hydraulic systems

Compressed Air Filters

Compressed Air Filters

Purge particles, oil, and other contaminants from air lines to prevent damaging equipment

Compressed Air Regulators

Compressed Air Regulators

Ensure continuous, safe operation of air-powered equipment by controlling air pressure

Compressed Air Filter/Regulator/Lubricators

Compressed Air Filter/Regulator/Lubricators

Deliver clean, lubricated air at the desired pressure to a component in your line

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

Safety Equipment

Fire Hose Nozzles

Fire Hose Nozzles

Attach to your fire hose to create a spray or stream of water

Containers, Storage, and Furniture

Drum Faucets

Control the flow of liquid from drums, tanks, carboys, and other containers
