The off-gassing device contains a stainless steel float and hardened stainless steel seat and disc. ALD 2000R Off-Gas Relief Valve is an ozone-compatible solution to effectively vent undissolved ozone and air from ozone water systems.
The device contains a float-operated valve. As liquid enters the device, the float rises closing the valve, and the valve opens when off-gasing ozone/oxygen levels increase.
