Characteristics
Fully welded body structure to avoid leakage.
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.
A proprietary valve seat (multiple seal construction) guarantees 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.
It can provide direct buried valve, the operator does not need to enter the well, and the T-handle can be used on the well for convenient and safe.
It can be equipped with a dispersing valve structure, which is convenient for management and safer.
