What is the Resilient Seated OS&Y Type Flange Gate Valve？

Flanged OS&Y gate valve refers to the gate valve with external stem and external stem (or external screw and external stem) gate valve with flange connection. It operates by opening and closing a gate-type disc, raising the gate to allow water to flow through the valve, and lowering the gate to shut off water flow through the valve. The opening and closing part of the rising stem elastic seat gate valve is the gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The valve uses the compensation function of the elastic gate to produce a small amount of deformation to achieve a good sealing effect. It can be widely used as a cut-off device in fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textiles, and energy systems.
