Products Feature:
1. The valve is forced sealing type, which can automatically compensate the normal wear of the sealing surface, zero leakage and long service life.
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.

FAQ
Q: Can it be used in high temperature condition?
A: Yes, the valve can use different materials according to different working conditions to meet customer needs.
Q: Are there compensating elements between the RAMS?
A: The ram adopts a special structure, wherein the ram is separated from each other and a central push rod, the two RAMS are set relative to each other, the outer sealing surface is parallel to each other, there are several pressure springs on the inner surface of the two RAMS, and the central push rod is fastened between the two RAMS through its lower end head and the card groove matching the lower end of the two ram sides.
Q: Does the valve come with lifting lugs?
A: Our valves usually come with lifting lugs, unless the caliber of the valve is too small or you don't need them.
Q: Are there any special precautions for installation?
A: There are no special requirements, but it should be noted that the installation position of the valve should not affect the operation of the equipment, pipelines and the valve body itself, and the aesthetic appearance of the assembly should be considered.
Q: How is the opening and closing direction of the universal valve stipulated?
A: The opening and closing direction of the general valve is clockwise for closing and counterclockwise for opening.
Q: What is critical pressure? What is the critical temperature?
A: The temperature at which a substance is in a critical state is called the "critical temperature". The liquefaction pressure corresponding to critical temperature is called critical pressure.
Q: What is the degree of supercooling?
A: The absolute value of the difference between the condensate temperature and the saturation temperature at the corresponding pressure.
Q: How is the travel of gate valve regulated? How to specify the travel of the stop valve?
A: When the gate valve is fully opened, the gate plate should be higher than the inner diameter of the channel
Q: What factors should be considered when selecting sealing material?
A: The basic requirements of sealing surface materials are 1, heat resistance 2, water resistance 3, abrasion resistance 4, erosion resistance and corrosion 5, hardness 6, expansion coefficient 7, processing technology 8, weldability
Q: What kind of internals are usually configured for the No. 5 internals specified by the API?
A: Seat, gate, disc, ball stack STELLITE, stem 13Cr
