What is the purpose of a valve?
Valves provide several functions, including:
Regulating flow and pressure within a piping system. Controlling the direction of flow within a piping system. Throttling flow rates within a piping system. Improving safety through relieving pressure or vacuum in a piping system.

Resilient seated gate valves made of speclal rubber elastlcly full wrap-plece valve structure, and the general absence of gate leakage or rust compared to other phenomena.  Overcome their common seal bad, elastic fatigue, wear rubber aging and Sealing ruts and oth-erdefects, Produced by ths elastic saeling full compensation of small quantities of deformation to achieve a good sealing effect.  It can be widely used in water supply, petrochemical, metallurgy, shipbuilding, food, pharmaceuticals and energy systems and other fluid line is used as a regulator and shut-off devices.

The product is designed for high-rise, tall buildings, used to solve the high-rise building water supply and water for fire control system for traffic flow, high sensitivity,the resistance to flow, lesser, check seal effect is good, requirements do not produce water hammer occasion. This product has the reasonable design, the advantages of long life.

The range can be engineered to suit your application, with body construction, material, and ancilary features optimised to meet your process needs. Being lSO 9001 certified, we adopt systematic ways to ensure high quality, you can be assured of outstanding reliability and sealing performance through the design life of your asset.

The advantages of fire gate valves include:
Synthetic rubber, using the overall package its good coverage and precise geometry size, ensure reliable sealing.

long service fife.
Corrosion resistance: inner chamber adopts non-toxic epoxy resin coating, prevent corrosion and rust, not only for drinking, and can be used in the sewage system.

Three "O" seal: stem with three.  Type ring sealing, low friction resistance, light switch, no leaking.

The resilient seated gate valves produced by our company by introducing European high-tech valve manufacturing technology achieves good sealing effect and using the compensation effect of elastic deformation caused by the overall rubber coating of the gate, and overcomes the phenomena of poor sealing, water leakage and rust of general gate valves.

It can be widely used as regulating and intercepting devices on fluid pipelines such as tap water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, shipbuilding, metallurgy, energy system, etc.

Advantages of gate valve
1.  After the gate valve is opened, the medium channel inside the valve body is straight, without any obstruction, and the flow resistance is very small.
2.  When opening and closing, the movement direction of the gate valve is perpendicular to the flow direction of the medium, the pressure is small, and the opening and closing is labor-saving.
3.  The height of the gate valve is large, so the opening and closing time is longer, and water hammer is not easy to occur.
4.  The two sides of the gate valve channel are symmetrical, and the medium can flow in any direction on both sides, so the installation of the gate valve is very convenient.
5.  The length of the structure is short, the manufacturing process is good, and the scope of application is wide.

The gate valve prodeced by YD factory is widely used in petrochemical industry, pharmacy and power industry ect. The valve is suitable to the various pipeline which is fully open or fully closed.
