1. It is equipped with a double valve seat differential pressure mechanism and SCCV closing system, which is reliable in action.
2. The valve is always in a water-sealed state to prevent steam leakage.
3. The open float is resistant to water hammer, and the unique design of the top of the bucket can prevent steam locking and air blockage.
4. The valve seat is located at the top of the valve body, and when the valve seat hole is opened, the impurities are discharged from the body under the action of the condensate under the action of pressure difference.
5. Able to withstand high back pressure (back pressure rate up to 90%).
Suitable for: high pressure, overheating occasions and heating equipment that produces condensate.
