Orifice Gate Valve

The Orifice Gate Valve is a specialized device designed for fluid, powder, and granular material conveying systems, combining flow guidance and on/off shut-off functions. Leveraging the company's years of experience in valve manufacturing and material handling technology, it utilizes a "parallel sliding gate valve + integrated flow guidance structure" as its core. Employing vertical or horizontal sliding opening and closing methods, it offers advantages such as smooth flow guidance, flexible opening and closing, anti-clogging and wear resistance, and reliable sealing. Manufactured in strict accordance with GB/T 9092, API 598, and ISO 4401 standards, it is suitable for medium to high pressure conditions from atmospheric pressure to 16MPa. Widely used in industries such as chemical, metallurgical, mining, building materials, new energy, and environmental protection, it completely solves the pain points of traditional gate valves, such as high medium flow resistance, easy material accumulation, poor flow guidance, and opening/closing difficulties, optimizing the medium conveying path and improving system operating efficiency and stability.

As an integrated hub for guiding and shutting off media in a media conveying system, this product focuses on the dual functions of "guiding + shutting off," with these three functions working together to connect conveying pipelines and various equipment. This enables efficient media control while ensuring stable operation and ease of use, making it suitable for various conveying process requirements.

Integrated flow guidance and opening/closing : Adopting an integrated design of "slide plate + flow guide plate", the slide plate realizes precise opening, closing and cutting off of the medium, while the flow guide plate optimizes the flow path of the medium, reduces flow resistance, and avoids the medium from eddying and stagnating in the valve body. It is suitable for medium and high pressure conditions from normal pressure to 16MPa, and can effectively guide and cut off various fluids, powders and granular materials, taking into account both smooth flow guidance and precise cutting off. It is suitable for conveying scenarios with requirements for medium flow efficiency.

Anti-clogging and anti-accumulation, suitable for multiple media : The insert plate adopts a flat optimized design, combined with a streamlined flow guide structure. The inner wall of the flow channel is precision polished (polishing accuracy up to 400#), smooth and clean, without protrusions or dead corners, which can effectively prevent the accumulation and jamming of powder, granular materials or viscous fluids. It is suitable for granular materials with a particle size of 0.1~50mm and various 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. The guide plate guides the smooth flow of the medium, further preventing material accumulation and pipe blockage, and completely eliminating the problem of material blockage and downtime. It is suitable for scenarios with high dust and high viscosity media.

Reliable sealing and excellent leak prevention 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 PTFE, FKM fluororubber, Stellite alloy and other materials suitable for medium and high pressure conditions. They can be flexibly selected according to the characteristics of the medium to achieve ANSI Class VI zero leakage, effectively preventing the external leakage of the medium and the entry of impurities, avoiding material waste, equipment damage and workshop dust pollution, and suitable for long-term stable operation in medium and high pressure scenarios.

1. Optimized flow guidance, resulting in extremely low flow resistance.

The core adopts an integrated structure of "slide plate + guide plate". The guide plate is designed with fluid dynamics optimization and is seamlessly connected with the slide plate. It can guide the medium to flow smoothly along the preset path, reduce eddies and flow resistance. Compared with traditional slide plate valves, the resistance is reduced by more than 30%, improving the medium delivery efficiency and reducing system energy consumption. The guide structure is adaptable to different flow requirements, can avoid the medium impacting the inner wall of the valve body, extend the service life of the equipment, and is suitable for high flow rate and high velocity delivery scenarios.

2. Flexible opening and closing, precise and controllable.

It adopts a sliding plate structure, which is driven by manual, pneumatic, electric or hydraulic actuators to move the plate smoothly. The opening and closing stroke is controllable, without jamming or deviation, and the switching is flexible and the response speed is fast (manual drive can complete the operation quickly, and pneumatic/electric/hydraulic drive can achieve a response in seconds). It is equipped with a precise limit mechanism to ensure that the opening and closing are in place and avoid media cross-flow caused by incomplete opening and closing. It is suitable for conveying conditions with frequent opening and closing, and takes into account both convenient operation and precise control.

3. Anti-clogging and wear-resistant, suitable for multiple media and various working conditions.

The valve body, slide gate, and guide plate are made of cast steel or stainless steel (304, 316L, CF8/CF8M optional) precision casting, with a robust structure that can adapt to harsh environments such as high dust, high humidity, mild corrosion, and medium to high pressure. The surfaces of the slide gate and guide plate are hardened or hard alloy welded (HRC≥55), with excellent wear resistance, corrosion resistance, and impact resistance, which 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 and is suitable for various media such as hydraulic oil, clean water, chemical fluids, powders, and granules, with a wide range of applications.

4. Compact structure and strong installation adaptability.

Adopting an integrated and compact design, it integrates flow guidance and opening/closing functions into one compact size. Compared with the traditional "gate valve + flow guide valve" combination solution, it reduces the installation space occupied by more than 50%, making it particularly suitable for workshop scenarios with dense piping and limited space. The nominal diameter covers DN50~DN500, and the interface adopts GB/T 9113 and ANSI B16.5 standard flange connection, which can be seamlessly connected with various pneumatic conveying systems, storage silos, conveying pipelines, and reaction 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 pipeline layout requirements.

5. Withstands medium and high voltage, and operates stably and reliably.

Designed specifically for medium and high pressure conditions ranging from atmospheric pressure to 16MPa, the valve body has undergone medium and high pressure strength and fatigue tests, demonstrating excellent pressure resistance with no deformation or leakage. The sealing structure is optimized for medium and high pressure conditions, with a tighter seal at higher pressures, achieving zero leakage under these conditions and avoiding safety hazards caused by media leakage. It can operate stably for extended periods within a temperature range of -30℃ to 400℃, meeting the continuous operation requirements of medium and high pressure transmission systems without the need for frequent maintenance.

6. Easy to maintain and cost-effective.

Adopting a modular design, vulnerable components such as the slide gate, guide plate, and seals can be disassembled and replaced individually without the need to completely dismantle the valve, improving maintenance efficiency by more than 50%. The standardized configuration of vulnerable components makes procurement convenient and cost-effective, and they are wear-resistant and durable, reducing the frequency of replacement and lowering system operation and maintenance costs. The integrated flow guiding and opening/closing design eliminates the need for additional flow guiding equipment, simplifies pipeline layout, reduces overall system investment, and offers a cost-effectiveness far superior to traditional combined valves.
