| Features | Rising stem,OS&Y,Bolted Bonnet or Pressure Sealed,non-rising stem option |
- Top-grade CF8M Stainless Steel：The valve body is made of CF8M stainless steel, a molybdenum - containing austenitic type. In the chemical industry, it forms a dense passive film with molybdenum's help, resisting strong acid and alkali media. This greatly extends the valve's lifespan and cuts maintenance costs. In marine settings, its rust resistance withstands seawater's high salinity and humidity, ensuring long - term stable operation.
- Precise Material Selection for Internal Components：The valve disc, made of the same CF8M stainless steel as the body, maintains good sealing against frequent medium scouring. The 316 stainless - steel hinge, with added molybdenum, offers better corrosion and fatigue resistance. It supports the valve disc stably during high - frequency rotation, enhancing the valve's durability.
- Innovative Anti - erosion Coating：A special high - hardness and wear - resistant coating is applied to easily - scoured parts like the valve seat. It resists particulate impurities in the medium, reducing wear and extending the seat's lifespan. The coating also optimizes the sealing between the seat and disc, preventing leakage even under high - pressure and high - flow conditions.
- Convenient and Efficient Bolted Bonnet：The bolted bonnet design simplifies valve maintenance. Operators can open it quickly with common tools, saving time and labor compared to welded or integral designs. Bolts tightly connect the bonnet and body, compressing the gasket to form a reliable seal, ensuring safe operation under high pressure.
- High - performance Swing - type Valve Disc：When the medium flows forward, the swing - type valve disc opens widely with low fluid resistance, ideal for high - flow systems like large - scale water and heating pipelines. When the medium reverses, it quickly returns to the seat under gravity and reverse pressure, protecting other pipeline equipment from backflow damage.
- Carefully Optimized Flow Passage：The valve's internal flow passage is smooth, reducing turbulence. This lowers fluid pressure loss, boosts energy efficiency, and decreases component wear. The optimized passage ensures stable performance under various flow conditions, supporting pipeline system stability.
III. Manufacturing Process Creating Outstanding Quality
- Precision Casting Ensuring Valve Body Quality：Advanced precision casting technology is used for the valve body. By controlling temperature, time, and cooling rate, the CF8M stainless - steel material integrates well. This process reduces internal defects, improves dimensional accuracy and surface quality, and strengthens the valve body for better overall performance.
- High - precision Machining for Key Components：Key components like the valve seat and disc are machined with high precision. CNC equipment controls the seat's sealing - surface accuracy to a micron level, ensuring a tight fit with the disc for optimal sealing. High - precision machining also enables smooth valve - disc rotation, improving response speed and efficiency.
- Strict Quality Inspection Ensuring Quality Assurance：Each valve undergoes strict inspection. Starting from raw materials, chemical composition and mechanical properties are checked. Non - destructive testing is done on the cast body, and after assembly, hydraulic, pneumatic, and sealing tests are carried out. Only valves passing all tests are approved for sale, guaranteeing high quality.
- Extremely Low Leakage Rate Ensuring Safety and Stability：Through strict sealing tests and optimized designs, this valve has a very low leakage rate. Whether the medium flows forward or in reverse, the disc and seat seal tightly, preventing leakage. In industries with high - leakage requirements like food, beverage, and pharmaceuticals, it ensures production hygiene and safety.
- Fast Response to Emergency Working Conditions：The swing - type valve disc gives the valve fast - response capabilities. When the medium's flow direction changes, it reacts quickly, crucial for emergency shutdown systems. Its fast response prevents accident expansion and reduces losses in industrial production.
- Extra - long Service Life Reducing Costs：With excellent materials, reliable structure, and fine manufacturing, this valve has a long service life. Under normal use and maintenance, it outlasts similar products, saving equipment replacement and maintenance costs. For large industrial projects, its long - life feature ensures continuous and efficient operation, cutting overall costs.
