Ductile Iron/WCB body

The body material is QT450 or WCB, and the chemical composition and mechanical properties meet the requirements of national standards. Material reports can be provided.

Processed by CNC precision machine

The valve body and inner parts are processed by CNC precision machine with high precision.

Two-way sealing

Adopt body sealing structure, which is different from the conventional plate sealing structure in the market, and can realize two-way sealing.

Multiple seats available

There are rubber soft seals and stainless steel hard seals available. The valve plate and other parts can also be selected according to the working conditions.

More wear-resistant

The valve seat is welded with stainless steel, which is more wear-resistant and has a longer service life.

Reduce torque

The valve shaft is supported by self-lubricating sleeve bearings, which can reduce the friction produced during valve shaft transmission and reduce torque.
