Detailed Product Description DIN Gate Valve Material: The body material: GG25,GGG40/GGG50 The disc material :DI/SS316/SS304/AL-BZ The stem material:SS410/SS416/SS420/SS304/SS316 The seat material:NBR/EPDM/PTFE/VITON Product Introdution Gate valves normally have flanged ends which are drilled according to pipeline compatible flange dimensional standards. Gate valves are typically constructed from cast iron, ductile iron, cast carbon steel, gun metal, stainless steel, alloy steels, and forged steels. Gate valves are characterised as having either a rising or a nonrising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated. Nonrising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position, since the gate travels up or down the stem on the threads without raising or lowering the stem. Nonrising stems are used underground or where vertical space is limited
