FULLY WELDED BALL VALVES · OEM & ODM
One welded body.
Nothing to leak from.
Lever, gear, direct-buried and balancing series for gas, district heating and oil pipelines. Forged carbon steel (ASTM A105 / A350 LF2) or A182 F304 / F316 stainless — DN15 to DN1400, PN16 to PN420. Hydro-tested and traceable by heat number.

PRODUCT RANGE
4 SERIES · DN15 – DN1400
Four series. One welded body.
Pick the operating type that matches your pipeline. Body, seal design and test standard stay the same — there is no body joint to leak from and no gasket to replace.
Gear Operated
A reduction gearbox cuts operating torque enough for single-hand use, so a DN1200 mainline valve still turns by hand.

Buried & Underground
Extended stem, sealed shaft and 3PE coating for direct burial in district heating and gas mains. No body joint to corrode.

Balancing Valve
Same welded body, plus V-port trim and a graduated locking dial — so the valve can balance the branch, not just shut it off.

MANUFACTURING
IN-HOUSE · YONGJIA, WENZHOU, ZHEJIANG
Machined, assembled and tested under one roof.
Bodies, balls and stems are machined on CNC centres in Yongjia, then welded, assembled and hydro-tested before coating. The workshop in these photos is the one that builds your order.
