TLV JA3 Free Float Air Trap with Tight Shut-Off for Air Service
Features
Light free-float air trap for pipe-end installation to automatically drain condensate and oil from compressed air systems.
- Self-modulating free float provides soft, continuous, and smooth, low velocity discharge as process loads vary.
- Perfect air-tight seal, even under low-load conditions
- Only one moving part, the free float, prevents concentrated wear and provides long maintenance-free service life.
- Built-in screen with large surface area ensures extended trouble free service.
- Manual blow down device allows cleaning of the valve seat from outside during operation.
- Major internal parts made of stainless steel.
