Core product

Parallel Double Disc Gate Valve

● This double gate valve has advanced design concepts and incomparable characteristics of ordinary valves. As a hydraulic control system, the product effectively solves the leakage caused by long-term unresolved impurities causing damage to the lock cover.

● In order to meet the requirements of different users, valves have national standards and American standards. In every system, there are general purpose plate valves and oil field specific valves.

● This double gate valve adopts a sealing structure and a special type of spring. Make the sealing pair consistent with any position so that residual dirt (such as sediment, welding slag, etc.) can be completely scraped off and can be cut on the cover. damaged and working fine

● Since the spring self-sealing structure in the double gate valve can automatically compensate for the normal wear of the valve cover, on the one hand, the sealing leakage rate is strong, on the other hand, the service life of the valve is greatly improved, saving costs for the enterprise.

● Double gate valves should adopt a wedge-shaped roller switch mechanism to open and close the valve gently. For example, the patented valve PN4.0MPADN300 can be easily opened and closed by just one person using a handwheel. Practice has proved that under the same pressure level and caliber, the opening and closing torque of the patented valve is half that of ordinary valves.

● Since this product adopts a special switching mechanism, it prevents the normal gate valve from heating up and causing the gate to be killed by the gate.

● There is an automatic drainage system at the bottom of the double gate valve, which can always keep the valve body cavity free of residue.

● There is a dust-proof mechanism in the valve body to ensure that the inner cavity of the double gate valve will not be invaded by dirt and the internal mechanism will not fail.

Core product

Ceramic Ball Valve

● All parts in contact with the medium are structural ceramic materials with extremely high chemical stability and hardness (Rockwell hardness hrc90), second only to diamond. Therefore, the valve has extremely high wear resistance, corrosion resistance, corrosion resistance, good thermal insulation and small thermal expansion.

● Ceramic ball valves are manufactured using advanced grinding equipment and technology, with high roundness precision and good surface quality. After grinding with the valve seat, good sealing performance can be obtained.

● The self-lubricating properties of ceramics have completely changed the problems of metal hard-sealed ball valves that are prone to leakage, have high torque, and have sealing surfaces that are not corrosion-resistant.

● The good wear resistance of ceramics makes the valve durable and reliable, with a long service life, which is 2-4 times that of titanium alloy valves and Monel alloy valves.

● This kind of valve is used for granular media with high hardness, or media with soft particles but corrosion. It has incomparable advantages and is also a valve suitable for such media.

Core product

Double Gate Double Seal Mining Valve

● The seal adopts double sealing. The inner ring is made of tungsten carbide, which has strong wear resistance, and the outer ring is made of polyurethane to completely seal the gate and achieve zero leakage.

● The gate adopts parallel double gate. The parallel gate is made of stainless steel and sprayed with tungsten carbide. Tungsten carbide has extremely strong wear resistance. The parallel double gate has the characteristic that the switch does not jam, making the gate completely sealed.

● The bottom of the mining valve is lined with ceramic for wear resistance.

● For mining valves, the sealing surface has zero leakage and uses hardness and thickness to achieve wear resistance.

● The maximum pressure of this product can be 150LB---1500LB. The gate is completely self-developed (patent application) and can be completely sealed even in a 1500LB medium environment. Note: It is strictly prohibited to disassemble the gate without permission. Disassembly may result in failure to assemble or leakage after assembly.
