Oil Purge Valve with Counter Weight

RFF purge valves with counter weights are valves with a normal primary closing system and a secondary closing system operated by the counter weight falling. The normal closing system is designed to provide a seal for a long period. The secondary closing system is a quick but temporary closing.

The main use of these valves is for oil purging in NH3 refrigeration systems.

There are two sizes available: DN8 and DN15.

Possible outlet connections include:

  • BUT welding
  • 1/2¨BSP
  • 1/2¨BSP + CAP
