Details

Construction

  • Solid brass body and valve
  • Stainless steel spring and roll pin
  • 2" thread size
  • Nitrile seal

Features

  • High flow valve provides optimum performance
  • Controls excess air flow (SCFM in only one direction)
  • Automatically senses change in air flow and shuts off the flow in the event of a surge in excess of valve flow rating thus preventing hose whip

How It Works

  • Safety check valves operate by using the pressure differential across the valve to operate the valve and spring assembly. The pressure is directly related to the flow of air (SCFM) through the valve.
  • When the pressure differential is within operating limits - below the cutoff flow - of the unit, the force on the valve exerted by the spring is greater than that caused by the pressure differential. The valve remains open and normal operation continues.
  • After the repair is made, normal operation is automatically enabled when the pressure across the valve equalizes through the bleeder hole.

Safety Notes

  • Not for use in applications where 100% of the available air is required, i.e. sand blast, pile driving rigs, expansion joint blow-down pipes, etc.
  • Does not prevent backflow

Specifications

Confirms to OSHA regulation 1926.30 (b)(7) requiring a safety device at the source of the air supply and at branch air lines.
