Features:

1.The flow resistance is small. The body's internal media channel is straight through, the medium into a straight flow, flow resistance is small.
2.When opening and closing more effort, compared with the cut-off valve, because either open or closed, gate movement direction perpendicular to the flow direction of the medium.
3.A high degree of opening and closing time is long. The opening and closing of the gate is larger, the reduction is carried out through the screw.
4.Water hammer phenomenon is not easy to produce. The reason is that the closure time is long.
5.The medium can flow in any direction, easy to install. Both sides of the gate valve channel is symmetrical.
6.The valves disc is rubber-packed to get excellent sealing effect by the rubber's resilient deformation.
Non-rising resilient seated gate valves solve the problem in general gate valves such as leakage, rusting etc.
and saves installation space. It is used widely in tap water industry, sewage treatment, shipping construction,
petroleum, chemicals, food, pharmacy, textile, electric power, metallurgy and energy system's pipeline to adjust and shut off fluids.
