Russian Standard DN15-200mm Wcb Handwheel Globe Valve for Natural Fuel Gas

 The KJY41N-16C Russian standard globe valve is not only suitable for medium and low pressure, but also suitable for high pressure. It is also suitable for petroleum, chemical, pharmaceutical, fertilizer, electric power and other industries. It plays a role in cutting off or connecting the regulator in the pipeline. The products produced by KMO have follow advantages: reliable quality, reasonable price and perfect after-sale service.

Product features
1. Compacted structure, beautiful appearance, and reduced runway.
2. Reasonable matching of sealing materials and long service life.
3. The valve disc is conical, the valve stem is equipped with an inverted seal, and the sealing performance is good. The valve stem is flexible in operation and the opening and closing torque is small.
4. Various piping standards and connection forms (such as socket welding, butt welding, threaded connection) can be used.
5. V-shaped molded tetrafluoroethylene is used as the dynamic seal, and the packing is pressed as the initial seal. With the increase of medium pressure, the packing sealing performance is enhanced. It has self-sealing function and does not require manual maintenance. It is suitable for high and medium pressure pipelines. This valve is all equipped with an inverted seal. When the valve is opened, the valve must be fully opened to make the inverted seal work to increase the service life of the packing, especially in the specification of >=DN200 with high inlet and low outlet. The valve opens lightly and has a long operating force. Much smaller than ordinary valves.

Working principle
  Once the shut-off valve is in the open state, there is no more contact between its seat and the sealing surface of the disc, so its sealing surface is less mechanically worn. Because most of the valve seats and discs are easier to repair or There is no need to remove the entire valve from the pipeline when replacing the sealing element, which is very suitable for the occasion where the valve and the pipeline are welded together. The flow direction of the medium through this type of valve has changed, so the flow resistance of the stop valve is higher than that of other valves.
  When the shut-off valve starts to close from the fully open position, as the valve flap drops, the fluid creates a pressure difference before and after the valve flap to prevent the valve flap from falling, and this resistance increases rapidly as the valve flap drops.
