Features and Benefits

Robust Valve Body

The cast steel valve body has sufficient strength to meet various working conditions and allows smooth fluid flow without obstruction.

Elastic Wedge Gate

The elastic wedge gate design automatically compensates for slight valve body deformation caused by pipeline stress, enhancing sealing performance and ensuring stable valve operation.

Sealed Welded Seat Ring

The seat ring is seal-welded for assembly, effectively eliminating potential leakage paths and significantly extending the valve’s service life.

T-Shaped Stem Connection

The stem features a T-shaped disc-stem connection, which helps prevent side stress from affecting the stem, ensuring smoother and more stable operation.

Corrosion-Resistant Packing System

Packing is treated with corrosion inhibitors to protect the stem from rust. The deep stuffing box design further extends packing life and reduces maintenance needs.
