40CF-AR Series - Air Vent Relief Valves

Product Type(s) : Relief Valves
Description :

For installation on pump suction lines, the 40CF-AR Air Vent Valve is designed to operate as a CIP return air relief, and operates against either vacuum or positive pressure. For proper operation, the valve should be mounted vertically.

WHERE TO BUY

FEATURES

  • The 40CF-AR is available in 1.5" - 4" (38mm - 102mm) sizes.
  • S-Line connections are standard. Other connections are available on request.
  • The 40CF-AR has a polypropylene ball that acts between the upper and lower machined seats.
  • The valve body is machined stainless steel, either 304 or 316.
  • Buna or FKM gaskets.
Key Applications
  • In suction lines when the 40CF-AR valve is under vacuum, the ball is pulled down against the bottom seat and seals against air entry.
  • When the vacuum is relieved in the process line, the ball loses its seal on the bottom seat, and any air in the process line is allowed to pass through the body of the valve and out of the system.
  • When flooded with liquid, the floating nylon ball is held closed against the upper seat by pressure.
  • Should the process line fill with air, the body of the valve will also fill with air. The ball falls from the top seat and the air is allowed to escape.
  • NOT FOR USE IN TANKS.
