The main components, including the body, ball, and stem, are typically made from high-quality CF8 (304 Stainless Steel) or CF8M (316 Stainless Steel), providing excellent corrosion resistance.
This specific model is designed for temperatures between -20°C and 120°C. For steam applications within this range, it performs exceptionally well due to its PTFE sealing.
A 2-piece (2PCS) ball valve consists of two main body parts. This design allows for a larger ball and better flow characteristics compared to a 1-piece valve, while being easier to maintain than a 3-piece valve.
Yes, due to its compact and robust flange design, it can be installed either horizontally or vertically to accommodate different spatial layouts in your piping system.
Yes, the valve is engineered for a "Zero Leakage" sealing grade, utilizing high-quality PTFE seats to ensure a tight seal even in low-pressure conditions.
The valve is manufactured according to the BS5351 standard, ensuring international compatibility and reliability for industrial flange connections.
