Low Pressure Slide Gate Valve

The Low Pressure Slide Gate Valve is a customized opening, closing, and shut-off control device for fluid, powder, and granular material conveying systems under low-pressure conditions. Leveraging the company's years of experience in valve manufacturing and material conveying technology, it utilizes a "sliding slide" as its core, employing a vertical or horizontal sliding opening and closing structure. It boasts advantages such as flexible opening and closing, anti-clogging and wear-resistant properties, reliable sealing, simple structure, and adaptability to low-pressure conditions. Manufactured in strict accordance with relevant standards such as GB/T 9092, API 598, and ISO 4401, it is suitable for low-pressure conditions from atmospheric pressure to 0.6MPa. It is widely used in industries such as chemical, metallurgical, mining, grain processing, building materials, and environmental protection, completely solving industry pain points such as valve opening and closing jams, poor sealing, material accumulation and pipe blockage, and cumbersome operation under low-pressure conditions. It simplifies pipeline control and improves system stability and convenience.

As a key control hub in low-pressure media conveying systems, this product features "precise cut-off via a slide plate" as its core function. Its three main functions work synergistically to connect conveying pipelines with storage and conveying equipment, achieving efficient media control while ensuring stable operation and ease of use. It is suitable for various low-pressure process requirements.

Low-pressure precision opening and closing : Adopting a sliding plate structure, the plate is driven to move smoothly by manual, pneumatic or electric actuators to achieve rapid opening and closing and precise cutting off of the medium. The opening and closing stroke is controllable, without jamming or deviation. It is suitable for low-pressure conditions from normal pressure to 0.6MPa. It can effectively block or conduct the conveying of fluids, powders and granular materials to avoid media leakage and crossflow. It is suitable for low-pressure conveying scenarios with basic requirements for opening and closing accuracy.

Anti-clogging and anti-accumulation, suitable for multiple media : The insert plate adopts a flat 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 avoid the accumulation and jamming of powder, granular materials or viscous fluids, and is suitable for granular materials with a particle size of 0.1~60mm and various low-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, making it suitable for scenarios with high dust, high viscosity and low pressure media.

Excellent low-pressure sealing and leak-proof performance : It adopts a fitting sealing structure, with the slide plate and valve seat tightly fitted. The sealing components are made of wear-resistant, aging-resistant, and low-pressure-condition-suitable materials such as PTFE, NBR (nitrile rubber), and fluororubber. They can be flexibly selected according to the characteristics of the medium to achieve zero leakage under low-pressure conditions. It effectively prevents the medium from leaking out and air from entering, avoiding material waste, equipment damage, and dust pollution in the workshop. It is suitable for long-term stable operation in low-pressure scenarios.

1. Low-voltage compatibility, flexible opening and closing without jamming.

The core adopts a sliding plate structure, which is designed for low-pressure conditions (atmospheric pressure to 0.6MPa). It has a simple structure, low resistance, and a smooth opening and closing process without impact or noise. The plate moves smoothly without jamming or deviation. With a precise limit mechanism, it ensures that the opening and closing are in place and avoids media cross-flow caused by incomplete opening and closing. The opening and closing response speed is fast. Manual drive can quickly complete the operation, while pneumatic and electric drive can realize remote control, which is suitable for low-pressure transmission conditions with frequent opening and closing.

2. Anti-clogging and wear-resistant, suitable for multiple media and scenarios.

The valve body and slide gate are precision cast from cast steel or stainless steel (304 and 316L optional). Some lightweight models use high-strength cast iron, balancing durability and economy. They are suitable for harsh low-pressure environments with high dust, high humidity, and mild corrosion. The slide gate surface is hardened (HRC≥50), exhibiting excellent wear resistance, corrosion resistance, and impact resistance. It can effectively resist the high-speed scouring of powders and granules and the erosion of corrosive fluids. The streamlined flow channel design eliminates dead corners for material residue, making it suitable for various low-pressure media such as hydraulic oil, clean water, chemical fluids, powders, and granules, with a wide range of applications.

3. Simple structure and strong installation adaptability.

Adopting an integrated and simple design, it has a simple structure and compact size, taking up less installation space compared to traditional low-pressure valves. It is especially suitable for low-pressure conveying scenarios with dense pipelines and limited space in workshops. The nominal diameter covers DN50~DN600, and the interface adopts the GB/T 9113 standard flange connection, which can be seamlessly connected with various low-pressure pneumatic conveying systems, storage silos, conveying pipelines, and unloading equipment. It supports multiple installation methods such as horizontal and vertical, without the need for complex modifications, and has extremely strong adaptability, which can flexibly adapt to different low-pressure pipeline layout requirements.

4. Easy to operate and extremely low maintenance cost.

Supports manual, pneumatic, and electric drive modes. The manual drive features an ergonomic handle design, making operation effortless and flexible, allowing for quick manual intervention in emergencies without requiring specialized skills. Pneumatic and electric drives enable remote control and automated linkage, adapting to industrial automated production lines and eliminating the need for on-site manual operation, significantly improving operational efficiency. Adopting a modular design, vulnerable components such as gate plates and seals can be individually disassembled and replaced without the need for complete valve removal, improving maintenance efficiency by over 60%. Standardized configuration of vulnerable parts ensures convenient and low-cost procurement, while also being wear-resistant and durable, reducing replacement frequency. The equipment operates with low vibration and a low failure rate, allowing for long-term continuous operation.

5. Reliable low-pressure sealing and stable operation.

The sealing structure is optimized for low-pressure conditions, with the slide gate and valve seat fitting tightly. The sealing components are made of flexible materials suitable for low-pressure scenarios, ensuring stable sealing performance and achieving zero leakage under low-pressure conditions, thus avoiding media loss and environmental pollution. The valve body has undergone low-pressure strength testing and shows no deformation or leakage. It can operate stably for a long time within a low-pressure range of atmospheric pressure to 0.6MPa and a temperature range of -20℃ to 200℃, meeting the continuous operation requirements of low-pressure transmission systems and eliminating the need for frequent maintenance.

6. High cost-performance ratio, suitable for low-voltage essential applications

Specifically designed for low-pressure applications, this valve features an optimized structural design that ensures performance while maintaining reasonable manufacturing costs, offering a significantly higher cost-effectiveness compared to general-purpose valves. It seamlessly integrates with our low-pressure pneumatic conveying systems and storage equipment, making it suitable for industries with high-pressure requirements such as chemical, mining, and grain processing. No additional high-pressure components are needed, reducing overall system investment. Non-standard customization is supported; the gate plate size, sealing material, and nominal diameter can be adjusted according to media characteristics, installation space, and drive method to meet individual customer needs.
