HVAC systems and HVAC systems during operation, water heating, release gases such as hydrogen, oxygen brought about a number of adverse effects may damage the system and reduce the thermal effects of these gases, such as not timely drain will have many adverse consequences . Caused by oxidation, such as: corrosion; the formation of airbags in the radiator; hot water circulation is not smooth uneven, some radiator local hot; pipeline with the noise when the gas is running; air and vortex phenomenon of the circulation pump. Therefore, the exhaust system must be discharged in time, we can see that use of the important role of automatic Oven Valve.

A, Features:
1). The only exhaust, undrained. Steam, water separator plate design using a special structure, guarantee never drainage when the exhaust.

2). And reliable performance. Emission device materials using the PK-EP. And all known synthetic material compared to the PK-EP has the best performance and highest reliability. The PK-EP can withstand high temperatures than the exhaust valve. The operating temperature is much higher. The material of EPDM O-ring optimized to ensure that still have good flexibility and operational reliability under high temperature O-ring. The internal spring of the exhaust valve spool to the use of special materials, and imports of nickel-plated stainless steel to prevent oxidation if the oxidation of the spool movement; exhaust valve exhaust mechanism is very reliable, at the factory, each Gas Burner Valves through the exhaust gas experiments and pressure sealing experiment. The individual components are precision cast, the perfect assembly.

3). As long as the system pressure, the exhaust valve will be continuous exhaust.

B, the main purposes:
The exhaust valve is used to automatically: independent heating system; central heating system; radiant floor heating system; solar heating systems; heat pump system; central air conditioning; heating boiler.

C, automatic exhaust valve works
When there is air in the system, gas gathered in the upper part of the exhaust valve, bubble accumulation in the body to float with the water level dropped, thus opening the exhaust piston; the gas is drained, the water level rises, the float will also rise, turn off the exhaust Pistons. Tighten the bonnet of the valve body side, the exhaust valve to stop the exhaust Typically, the valve cap should be turned on.
