Characteristics

The valve body is cast from high quality materials and a reasonable casting process. It is suitable for all shapes and costs less than forged steel.

The valve seat has multiple sealing structures to ensure zero leakage.

The stem is blown out to prevent the stem from being ejected from the valve body due to improper operation.

It is equipped with fireproof and anti-static devices to prevent fires.

The valve seat seal and the stem seal are provided with a grease filling valve. When the sealing surface is damaged and causes leakage, the sealing grease can be injected for emergency repair.

The venting valve and the drain valve are arranged on the upper and lower sides of the valve body to ensure safety, reliability and convenient use.
