Barworth model No. 435 automatic shut-off valves are for use with "C" cable manifold assembly. It is designed to prevent loss of pressure in individual cable outlets if there is a loss of flow from the main inlet source. Shut-off is bubble-tight. This valve will close when pipe pressure falls below 0.2 PSIG. Features generous flow with minimal pressure drop.

  • Brass construction and tin-plated.
  • 1/4" NPT connections.
Tester will confirm output efficiency of compressor. If reading is normal (green zone), compressor is producing the required output. If reading is below
normal (red zone), compressor should be removed and serviced or repaired. Tester can be used while compressor remains in air dryer.
