With its unique structural design and performance optimization, the Y-type stop valve has shown many significant advantages in industrial fluid control. The specific advantages are as follows:
1. Superior fluid dynamic performance
Low flow resistance design
The Y-type flow channel makes the medium flow direction and the valve stem at an angle of 45°~60°, which reduces the fluid resistance by 30%-50% compared with the traditional stop valve, effectively reducing the pressure loss and energy consumption.
High flowability adapts to complex media
The inner wall of the flow channel is smooth, and the conical sealing surface with "scraping effect" can automatically remove impurities, which is suitable for the stable control of particle-containing and high-viscosity media (such as mud and oil products).
2. Enhanced sealing reliability
Dual sealing technology
The combination of PTFE soft seal and metal spiral wound gasket hard seal is adopted, and the bellows design achieves two-way zero leakage (leakage rate is less than 10^-6 mL/s), meeting the stringent standards such as nuclear power.
Self-tightening sealing structure
The higher the medium pressure, the tighter the sealing surface fits, especially in high-pressure conditions (such as 10MPa steam system).

3. Outstanding material and durability
Corrosion resistance and high temperature performance
The valve body can be made of F321 stainless steel (containing titanium), duplex steel and other materials, with acid and alkali corrosion resistance increased by 50%, high temperature tolerance up to 600℃ (short-term 800℃), suitable for extreme environments such as chemical industry and nuclear power.
Long life design
The valve stem is tempered and nitrided (hardness HRC≥50), and the sealing surface is welded with Stellite carbide. The opening and closing life exceeds 100,000 times, and the maintenance cycle is extended by 40%.
4. Convenient operation and maintenance
Fast opening and closing and low torque
The working stroke is small, the opening and closing time is short, and the pneumatic/electric actuator supports high-frequency automatic operation.
Modular maintenance
The bolted or self-tightening valve cover structure simplifies disassembly and assembly, and the replacement time of the wound graphite gasket is reduced by 70%, reducing maintenance costs.
5. Wide application adaptability
Adaptable to nominal pressure PN1.6~6.4MPa (maximum PN40/Class 600), temperature range -29~550℃, covering industries such as petroleum, electricity, and pharmaceuticals, meeting diverse needs such as high-pressure steam, LNG storage, and aseptic environment.
Summary: The Y-type stop valve has significant advantages in high-pressure, high-temperature, and corrosive media control scenarios through low-resistance flow channels, double sealing mechanisms, corrosion-resistant materials, and modular design, and has become a core component of modern industrial fluid systems.
