Forged Carbon Steel Trunnion Ball Valve

Large pipes need large valves. But a hand lever cannot turn a big ball valve. The torque is too high. Our Forged Carbon Steel Trunnion Ball Valve has a worm gear operator on top. The gear reduces the speed and multiplies the torque. So you can turn a big valve with a small hand wheel. The model Q341F-16C means "3" is worm gear, "4" is flange, "1" is straight through, "F" is PTFE seal, "16C" is PN16 and cast steel WCB. The body is forged or cast. The design follows API 6D. The worm gear box is fully sealed. It has IP65 protection. There is a mechanical limit stop. So you control the full open and close positions exactly.

Suhao makes the worm gear box for this Forged Carbon Steel Trunnion Ball Valve ourselves. The gear is high-strength ductile iron. The efficiency is high. The wear is low. If you open and close it two times per day, it can run for 3 years with no problem. Our fixed ball valve Q341F-16C and carbon steel high platform floating ball valve can be used together with this product. Each Forged Carbon Steel Trunnion Ball Valve gets a matching test before shipping. We make sure it turns smoothly with no sticking. We do a 100% shell water test and seal air test. The gear box also gets a no-load and load test.
