Same lifetime as the pipeline system ;

Maintenance-free , no adjustment or lubrication with no running costs ;

Bi-Directional valve.

Main Characteristics:
One-piece welded body & End piece connection pipe (Connection dimension to ASTM / EN / KS / JIS / GOST Standard .etc will be available.

Bubble tight excellent sealing with PTFE+C seats.

Pre-loaded seat springs ensure leak-tight at low pressure and reduce valve operational torque.

Anti blow-out stem.

Double O-rings ensure the stem sealing and are replaceable.

Stem dry bearing, metal with PTFE coating having self-lubricating capabilities. (Additional lubricant unnecessary.

The all-welded ball valve is welded with a seamless steel tube. The entire valve is bolt-free and has no external leakage due to handling collisions and casting sand holes. It is lightweight and easy to transport and install. Because the seat is designed to be loaded by springs or butterfly springs, it is adaptable to changes in pressure and temperature, and does not create any leakage during the pressure and temperature range.
