Fluid Handling

Check Valves

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

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

Power Transmission

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
