Safety Warning

Full Product Description

Parker’s DOT Single & Double Check Valves were designed to deliver increased flow capacity and reliable sealing, while reducing product size and cost. Check valves allow for compressed air to flow in one direction while preventing the flow in the reverse direction. For total system protection, check valves are typically installed upstream of the system component they are protecting. Parker offers our Air Brake DOT Check Valves with both composite and brass bodies. Multiple connection ends are available to fit then needs of your air braking system.

Unique to Parker, and patent pending, is the double check, or shuttle valve design. The air brake double check valve allows for the flow of compressed air both around and through the shuttle, creating up to 40% more air flow. The valve seal location remains centered with the seat for a consistent seal. This air brake DOT valve has been tested to withstand extreme temperatures and extensive cycle life.
