Back Flow Prevention Control Valves

Back Flow Prevention Control Valves

Also known as check valves, these valves prevent backward flow of air in your system. They only open in one direction and close when the airflow stops to prevent the air or gas from reversing in the system.

Heavy Duty

The body on these valves is made from cast brass, which has good strength, corrosion resistance, high durability, and heat resistance.

Inline

Screw these directly into the discharge line. The outlet and inlet on the valve are the same size so they can be easily integrated into your system.

Compact

Smaller than standard check valves, compact valves can be used with small compressors and have a minimal footprint in pneumatic circuits. They are often used as tank check valves for small compressors or as components in pneumatic circuits.

Corrosion Resistant

Keep corrosive elements from damaging your check valves. When used in normally dry conditions, these valves resist fresh water, mineral oils, and fuels. When used in industrial conditions, they are partially resistant to neutral and alkaline salt solutions and some organic compounds.

Cold-Start Air Compressor Unloader

Vent trapped air in systems that are subject to low temperatures and low starting voltages to remove load from the cylinder pistons. Install these valves into any port upstream of the tank check valve to bleed extra air from the compressor head during the first few revolutions.

Quiet Operation

Keep surrounding areas quiet by using these valves. They screw directly into the receiver and attach to the compressor's discharge line at the inlet.
