Products Feature:
1. The Five-piece flat gate valve with diversion hole is adopted. The five-piece structure of the gate adopts the telescopic structure, which greatly reduces the weight of the gate.
2. Significantly reduce the friction between the main gate and the seat in the opening process, further reduce the opening and closing torque, avoid the phenomenon of the main gate stuck, and extend the service life of the valve.
3. The upper end of the main gate is fixed to the valve stem, and there is a V-shaped bevel between the main gate and the contact surface of the slave gate, which greatly enhances the sealing effect
4. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.
5. The valve is suitable for a variety of media, including water, oil, gas, etc., widely used in petroleum, chemical, metallurgy, electric power and other industries.
6. It can clean the pipeline through the ball.

FAQ
Q: Why choose the Five-piece flat gate valve with diversion hole?
A: Because there is a diversion hole to help the valve cavity pressure relief, and in the valve opening and closing, the flat gate valve with a diversion hole will be more labor-saving. The plate gate valve with a diversion hole also has an obvious role in protecting the sealing surface, whether it is fully closed or fully opened, it is closely combined with the sealing surface, which makes the sealing surface not directly washed by the medium and extends the service life.
Q: What are the advantages of the valve?
A: The structure of the flat gate valve to the diversion hole is smooth, which can keep the internal clean of the pipeline, and is widely used in the oil and gas transmission and ball transmission of the long distance pipeline
Q: Can I clean it with a pig?
A: Of course, the valve is full diameter with diversion hole, can be pigged directly with the pig.
Q: No sliding friction between the valve seat and the valve seat during the closing process to avoid wear of the sealing surface?
A: In the process of the wedge frame rising with the valve stem, the two inclined plates are unable to support the main gate. In order to make the main gate free from the seat, the two inclined plates are pulled back to the position by the contraction of the tension spring, which significantly reduces the friction between the main gate and the seat during the opening process, further reduces the opening and closing torque, avoids the phenomenon of the main gate sticking, and extends the service life of the valve.
Q: Can I request special configuration?
A: According to the specifications, we will meet your needs
Q: What is the pressure part of the valve? What parts do controlled pressure parts refer to? Please be specific.
A: The pressure part of the valve refers to the parts that bear the pressure of the medium, such as the valve body, the valve cap, the end cap, etc. Pressure control parts refer to the main parts of the valve cavity, such as the valve stem, sealing pair, and upper sealing seat.
Q: What torque should be included in the total stem torque calculation of gate valve?
A: The total torque of the valve stem should include the valve stem sealing force, the friction torque between the valve stem and the packing, the action of the medium and the axial force on the valve stem.
Q: What is the sealing specific pressure of the sealing surface, the actual specific pressure and the allowable specific pressure? What is the relationship between them?
A: The average positive pressure acting on the unit sealing surface becomes the specific pressure of the seal, to ensure that the required specific pressure of the valve becomes the actual specific pressure, and the maximum specific pressure allowed by the valve sealing material is called the allowable specific pressure.
Q: What is the structural length of the valve? Why should it be regulated?
A: Straight-through valve structure length: the distance between two perpendicular to the valve axis plane at the end of the valve body channel, Angle valve structure length: the distance between the plane perpendicular to the axis of a terminal in the valve body channel and the other terminal axis of the valve body. For easy installation and replacement
Q: What is solid solution treatment? What is the purpose? How to check?
A: Solid solution treatment: refers to the heat treatment process of heating the alloy to a high temperature single-phase area to maintain a constant temperature, so that the excess phase is fully dissolved into the solid solution and then cooled quickly to obtain the supersaturated solid solution. The purpose of solution treatment is mainly to improve the plasticity and toughness of steel and alloy, and prepare for precipitation hardening treatment.
Objective: To fully dissolve various phases in the alloy, strengthen the solid solution, improve toughness and corrosion resistance, eliminate stress and soften, so as to continue processing or forming.
Q: What is nitriding? What is the purpose?
A: The process of nitrogen atoms on the surface of steel is called nitriding treatment, which aims to improve the hardness, wear resistance, corrosion resistance, and fatigue strength of the workpiece surface.
