Gate Valves

Dongjin valve have compact design and properly machinery which is completely in accordance with most updated international standards of API6D,ASME B16.34,DIN3202,GOST etc. Gate valves are characterised as having either a rising or a non-rising 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. Non-rising 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. Non-rising stems are used underground or where vertical space is limited. Dongjin gate valves are typically constructed from ductile iron, cast carbon steel, stainless steel, alloy steels, and forged steels.
