The High Pressure Slide Gate Valve is a customized opening, closing, and shut-off control device for fluid, powder, and granular material conveying systems under high-pressure conditions. Leveraging the company's years of experience in valve manufacturing and high-pressure material conveying technology, it utilizes a "high-strength sliding gate" as its core, employing a vertical or horizontal sliding opening and closing structure. It boasts advantages such as high-pressure resistance, precise opening and closing, tight sealing, anti-clogging and wear resistance, and structural stability. Manufactured in strict accordance with GB/T 9092, API 598, and ISO 4401 standards, it is suitable for high-pressure conditions ranging from 1.6MPa to 32MPa. It is widely used in high-pressure chemical, oil and gas, mining high-pressure conveying, metallurgical high-pressure systems, and new energy industries, completely solving industry pain points such as valve opening and closing jamming, seal leakage, excessive wear, and material accumulation clogging under high-pressure conditions. It strengthens pipeline high-pressure control and improves system operational stability and safety.

As a key control hub in high-pressure media conveying systems, this product is centered on "slide-type high-pressure precision cut-off," with three functions working synergistically to connect high-pressure conveying pipelines with storage and reaction equipment. It achieves efficient control of high-pressure media while ensuring stable operation and ease of use, adapting to various high-pressure process requirements.

High-pressure precision opening and closing : Adopting a high-strength sliding plate structure, the plate is driven to move smoothly by pneumatic, electric or hydraulic actuators, realizing rapid opening and closing and precise cut-off of high-pressure media. The opening and closing stroke is controllable, without jamming or deviation, and is suitable for high-pressure working conditions of 1.6MPa~32MPa. It can effectively block or conduct the conveying of high-pressure fluids, powders and granular materials, and avoid high-pressure media leakage and crossflow. It is suitable for high-pressure conveying scenarios with strict requirements for opening and closing accuracy and pressure resistance.

Anti-clogging and anti-accumulation, suitable for multiple high-pressure media : The insert plate adopts a thick-walled optimized design, and the inner wall of the flow channel is precision polished (polishing accuracy can reach 400#), smooth and clean, without protrusions or dead corners, which can effectively prevent the accumulation and jamming of powder, granular materials or viscous fluids under high pressure. It is suitable for granular materials with a particle size of 0.1~50mm and various high-pressure fluid media. During the translation of the insert plate, it can scrape off the slightly adhered material on the inner wall of the flow channel, further preventing material accumulation and blockage, and completely eliminating the problem of material blockage and downtime. It is suitable for high-pressure, dusty and high-viscosity media scenarios.

High-pressure sealing with excellent leak-proof performance : It adopts a "double-fit seal + high-pressure buffer seal" structure, with the slide plate and valve seat tightly fitted. The sealing components are made of high-pressure resistant, wear-resistant, aging-resistant, and corrosion-resistant materials such as PTFE, FKM fluororubber, and Stellite alloy. They can be flexibly selected according to the characteristics of the high-pressure medium to achieve ANSI Class VI zero leakage. It effectively prevents the leakage of high-pressure medium and the entry of impurities, avoiding material waste, equipment damage, and safety hazards caused by high-pressure leakage. It is suitable for long-term stable operation in high-pressure scenarios.

1. High pressure resistance, stable structure with no deformation.

The core adopts a high-strength sliding gate structure, which is specially designed for high-pressure conditions of 1.6MPa~32MPa. The valve body and gate are made of high-strength cast steel and stainless steel (304, 316L, CF8/CF8M optional) precision casting. After high-pressure strength test and fatigue test, it has excellent pressure resistance, no deformation and no leakage. The gate adopts a thick-wall design, combined with a rigid linkage structure, which can resist the impact of high-pressure media and avoid opening and closing failure caused by gate deformation, making it suitable for high-pressure continuous operation conditions.

2. Anti-clogging and wear-resistant, suitable for various high-pressure media and scenarios.

The plate surface is hardened or hard alloy welded (HRC≥58), exhibiting excellent wear resistance, corrosion resistance, and impact resistance. It can effectively resist the high-speed scouring of powders and granules under high pressure and the erosion of corrosive fluids. The flow channel adopts a streamlined and optimized design, eliminating dead corners with material residue, reducing the flow resistance of high-pressure media, and preventing material accumulation and pipe blockage. It is suitable for various high-pressure media such as high-pressure hydraulic oil, chemical fluids, mineral powder, and ore particles, and is suitable for harsh working conditions such as high pressure, high dust, strong corrosion, and high wear.

3. Compact structure and strong installation adaptability.

Adopting an integrated and compact design, this valve optimizes the structural layout while ensuring high-pressure withstand performance. Its small size reduces installation space compared to traditional high-pressure valves, making it particularly suitable for high-pressure workshops with dense piping and limited space. Nominal diameters range from DN50 to DN500, and the interface uses GB/T 9113 and ANSI B16.5 standard high-pressure flange connections, allowing seamless connection with various high-pressure pneumatic conveying systems, high-pressure storage silos, high-pressure conveying pipelines, and reaction equipment. It supports both horizontal and vertical installation methods without complex modifications, offering excellent adaptability and flexibility to meet different high-pressure pipeline layout requirements.

4. Easy to operate and controllable maintenance costs.

Supports pneumatic, electric, and hydraulic drive methods (pneumatic/hydraulic drive is preferred for high-pressure conditions), equipped with a precise control mechanism, ensuring smooth operation and flexible switching. In emergencies, it allows for rapid manual intervention to ensure the safety of the high-pressure system. Pneumatic, electric, and hydraulic drives can be remotely controlled and automated, adapting to industrial automated high-pressure production lines. No manual on-site operation is required, significantly improving operational efficiency. A modular design allows for individual disassembly and replacement of vulnerable components such as valve plates and seals, eliminating the need for complete valve removal and improving maintenance efficiency by over 50%. Standardized configuration of vulnerable parts facilitates procurement, ensuring durability and reducing replacement frequency, thus lowering the maintenance cost of the high-pressure system.

5. High-pressure sealing is reliable, and operation is stable and safe.

The sealing structure is specifically optimized for high-pressure conditions, featuring a double-seal design for double protection. The seals fit tightly with the slide gate and valve seat, adapting to changes in high-pressure medium pressure. The higher the pressure, the tighter the seal, achieving zero leakage under high-pressure conditions. The valve body adopts a high-pressure sealing isolation design to prevent high-pressure medium from entering the actuator and bearings, extending the life of core components. It can operate stably for a long time within a high pressure range of 1.6MPa to 32MPa and a temperature range of -30℃ to 400℃, meeting the continuous operation requirements of high-pressure transmission systems and eliminating the safety hazards of high-pressure leakage.
