Stainless steel knife gate valve ANSI/DIN/JIS

Gate valves commonly have flanged ends which are drilled in step with pipeline compatible flange dimensional standards. gate valves are commonly made out of cast iron, ductile iron, cast carbon metallic, gun metallic, stainless-steel, alloy steels, and forged steels.

Gate valves are characterised as having both a growing or a nonrising stem. growing stems provide a visual indication of valve role because the stem is connected to the gate such that the gate and stem upward thrust and decrease collectively as the valve is operated. nonrising stem valves may additionally have a pointer threaded onto the upper cease of the stem to suggest valve function, since the gate travels up or down the stem on the threads with out elevating or reducing the stem. nonrising stems are used underground or where vertical area is limited.
