Ductile Iron Non-Rising Stem Resilient Seated Flanged Gate Valve
Product introduction:
Ductile Iron Non-Rising Stem Resilient Seated Flanged Gate Valve is a gate valve with soft seal, it is the best substitute product of traditional gate valve, can achieve sound sealing performance by the compensation function of micro deformation of elastic gate valve. As it is superior for its light and flexible switch, reliable sealing, excellent elastic memory and long service life, the valve can be widely applied to fluid pipeline, including tap water, polluted water, buildings, food, electricity, medicine, metallurgy and light textile, as adjustment and closure equipment.

Product features:
1. Low flow resistance, valve body internal medium channel is straight, medium into a straight line flow, flow resistance is small.
2, Save manpower for opening and closing compared with the globe valve, because whether open or closed, the movement direction of the gate is perpendicular to the direction of the flow side of the medium.
3. High height and long opening and closing time.The opening and closing stroke of the gate is larger, and the drop is carried out through the screw rod.
4, Low water hammer phenomenon due to long shutdown time.
5, Two ways direction, medium can flow to both sides in any direction, easy to install.
6. The structural length (the distance between the two connecting ends of the shell) is small.
