Characteristics
The valve body is made of forged steel to avoid defects such as shrinkage, cold separation and trachoma.
Seat piston effect: 1. Both upstream and downstream are single piston effect valve seat, namely DBB function; 2. Both upstream and downstream are double piston effect valve seat, namely DIB-1 function; 3. Upstream is single piston effect valve seat, downstream It is a double piston effect seat, DIB-2 function.
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.
Straight-buried valves are available, and the stem is extended to the needs of the project for ground operation and the corresponding grease, drain and venting devices are extended to the ground.
