Designed specifically for industrial fluid and powder control scenarios, the Pneumatic Y-Type 135° Three-Way Ball Valve (DN50 - DN300) stands out as a high-performance solution that combines efficient flow regulation, reliable sealing, and strong adaptability. Its unique Y-type 135° valve body structure ensures a flat flow path, minimizing fluid resistance and maximizing flow capacity—making it particularly ideal for powder conveying systems where "no dead space, no material accumulation" is critical. Whether used in chemical, food processing, or manufacturing plants, this valve effectively prevents secondary contamination of media and maintains stable operation even under harsh working conditions.
What sets this valve apart is its comprehensive adaptation to diverse industrial needs. From material selection to control mode configuration, every detail is optimized to meet different application requirements. For instance, the valve body offers multiple material options (WCB, 304, 316 stainless steel) to cope with corrosive or high-temperature environments, while the flexible seal choices (PTFE, PPL, hard seal) cover a wide temperature range of -30℃ to 450℃, ensuring tight sealing and long service life in various temperature conditions.
Key Product Features & Customer Benefits
Zero Leakage & No Media Retention: The precision-machined valve core and high-quality seal assembly achieve zero leakage, avoiding media waste or system contamination. The smooth, dead-space-free flow path prevents material accumulation—especially important for powder conveying to keep the pipeline clean.
Low Flow Resistance & High Flow Capacity: The Y-type 135° structural design of the valve body creates a flat, unobstructed flow channel, reducing fluid pressure loss and improving conveying efficiency. This is particularly beneficial for large-flow scenarios such as industrial water supply and gas transmission.
Multiple Control Modes for Automation: The valve supports pneumatic control (double-acting/single-acting) as the primary mode, and can be equipped with electric, handle, or turbine control upon request. For emergency situations, an optional handwheel clutch allows manual operation when the air supply fails, ensuring uninterrupted system operation.
Strong Environmental Adaptability: With a pressure rating of PN1.6 - 4.0MPa and a wide temperature range covered by different seal types, the valve is suitable for both low-pressure ordinary media and high-pressure, high-temperature industrial fluids. 304/316 stainless steel bodies are available for corrosive media like chemicals or seawater.
Compliant with Industry Standards: Manufactured in accordance with GB/T12238-2008, GB/T-12237, and API 6D/608 standards, and tested to GB/T13927-2008 and GB/T-26480/API 598 standards, the valve meets strict industrial quality requirements and ensures compatibility with existing pipeline systems.

FAQ
Q: Can this valve be used for food-grade powder conveying (e.g., flour, sugar)?
A: Yes. If you select 304 or 316 stainless steel as the valve body material (which meets food safety requirements) and PTFE seals (non-toxic and odorless), the valve can be used for food-grade powder conveying. Its dead-space-free flow path also prevents material residue, avoiding cross-contamination.Q: What should I do if the air supply is interrupted suddenly? Will the valve stop working?
A: No. The valve offers an optional handwheel clutch accessory. When the air supply is interrupted, you can engage the handwheel clutch to switch to manual operation, allowing you to continue adjusting the valve opening and ensuring the normal operation of the pipeline system.Q: Is the valve compatible with both metric and imperial flange standards?
A: Yes. The valve's flange connection complies with both Chinese standards (JB/T 79.1-1994, HG/T-20592) and international imperial standards (ASME B16.5). When placing an order, please specify the flange standard you require, and we will manufacture it accordingly.Q: What is the difference between single-acting and double-acting pneumatic actuators? How do I choose?
A: A double-acting actuator requires air supply for both opening and closing the valve, and it will stay in the current position if the air supply is cut off. A single-acting actuator uses air supply for one action (either opening or closing) and relies on a spring to return to the default position (normally closed or normally open) when the air supply is interrupted. Choose double-acting for general scenarios; choose single-acting if you need the valve to automatically return to a safe position (e.g., closing to prevent media leakage) in case of air supply failure.Q: Can the valve be used for high-temperature media (e.g., 400℃ steam)?
A: Yes. You need to select the hard seal option—its surface is coated with tungsten nitride, which can withstand temperatures up to 450℃, making it suitable for high-temperature media like 400℃ steam. Please note that when using high-temperature media, ensure the valve body material (e.g., WCB or 304 stainless steel) is also compatible with high temperatures.Q: What is the service life of the valve's seal? Do I need to replace it regularly?
A: The service life of the seal depends on the seal type and operating conditions. PTFE seals typically last 1-2 years in normal temperature (20℃ ~ 80℃) and non-corrosive environments; hard seals can last 3-5 years due to their high wear resistance. Regular inspection (recommended every 6 months) is advised—if you notice leakage or increased operating resistance, replace the seal promptly. We can provide replacement seals and maintenance guidance upon request.Q: Is the valve suitable for outdoor installation? Will rain or humidity affect its performance?
A: The basic version of the valve is designed for indoor use. For outdoor installation, we recommend choosing optional waterproof accessories (e.g., waterproof solenoid valves, waterproof limit switches) and applying anti-rust coating to the valve body (especially for WCB material). These measures can prevent rain and humidity from causing corrosion or damaging the pneumatic components, ensuring stable outdoor operation.
