Stainless steel gate classification is more, relative model is much more. Such as welding, thread, flange connection. And the material also has 304, 316, 316 l, 2205 stainless steel and so on. On the market the most commonly used material is 304 stainless steel, stainless steel gate is the most popular way of connecting flange connection. Model corresponding Z41W - 16 p for the rising stem gate valves, stainless steel Z45W - non-rising stem valves 16 p also has, but application is relatively less. （ Specific stem, advantages and disadvantages non-rising stem can contact personnel consulting) Gate valves open parts for ram, switching mode is also very simple, lifting and installation of piping vertical direction so as to realize the switch valve. Gate valves are often used to fully closed or fully open pipeline medium flow, rarely used to adjust flow. Ram down closed pipeline, valve plate seal face by medium pressure to achieve better sealing effect, this depends on fluid pressure itself to strengthen the Industrial Valves sealing effect, called the sealing valve. Most of the gate valve is the use of the sealing technology. Gate valve has the advantage that for medium flow resistance is very small, long service life. But the disadvantages are more, such as take up the space is too big, relative to the butterfly Industrial Valves ball Industrial Valves cost is much higher, the weight is overweight, large-diameter gate valve is not suitable for installation in high altitude.

Every day of the year, there is some city or town in the world that is changing over to for cast iron valve.
