Oumefar DN20 G3/4 Air Vent Valve Automatic Brass Pressure Relief Valve Metal Air Evacuator for Exhaust HVAC System

• 【Automatic Exhaust】When the system is running with water or the system pressure is too high and full drainage is required, this automatic pressure relief valve can operate reliably. As long as there is a pressure difference between the inside and outside of the system, the exhaust valve will continue to exhaust
• 【Separation Tray Design】In order to ensure that water will not be discharged during the exhaust process, our vent valve uses a special structure-the design of the steam and water separation tray
• 【Principle Of Operation】The valve removes excess air during the operation of the exhaust system and HVAC system, and has the characteristics of high temperature resistance, rust resistance, and sealing
• 【Precision Construction】The inside of our emptying valve is made of high-precision parts, the exhaust mechanism is stable and
• 【Easy To Operate】Our drain valve is easy to disassemble and maintain,DN20 G3/4 threaded interface can adapt to most water heaters

Features: This valve features high temperature resistance, rust protection, reliably sealing. Remove excess air during the operation of the exhaust system and hvac system The exhaust mechanism is very and is cast from high-precision components It is convenient to demount and maintenance, while the water in the system will not out, so there is no need to empty the system. The steam and water separation tray is designed with special structure to ensure that the water will not be discharged during exhaust. As long as the system has pressure, the exhaust valve will continue to vent. It can be operated reliably, either when the system is running with water added or when the system pressure is too high and adequate drainage is required.
