Long Stem Gate Valve

Do you need to see if a valve is open or closed Just look at our Long Stem Gate Valve. The stem has trapezoid threads on the outside. As the gate moves up and down, the stem moves too. So operators can see the valve position with their own eyes. This reduces the risk of wrong operation. The stem is made of 2Cr13 or SS304 stainless steel. We use high-precision rolled thread processing. The stem nut is brass or ductile iron. So the friction is low. The opening and closing torque is light. The body has a full bore design. There is no reduction in size. This lowers flow resistance. It also lets you clean the pipe easily.

We have been a factory for more than 20 years. We know that threads can rust and stick in bad environments. So we add extra protection on our Long Stem Gate Valve. We put high-performance anti-rust grease on the stem before shipping. We also add a dust cover. Our factory has CNC boring and milling machines. We also have high-precision CNC lathes. So the stem we make is more accurate than national standards. This gives you stability after tens of thousands of openings and closings. We use CNC automatic grinders and horizontal lathes too. This ensures all parts have good concentricity. That stops leaks from the start.
