Product Detail
I. Product Parameters
1. Material Parameters
• Valve Body / Valve Core: 304 Stainless Steel (marked "CF8"), 316 Stainless Steel (marked "CF3M", stronger corrosion resistance)
• Seals: PTFE (Polytetrafluoroethylene, temperature resistance -20℃~180℃), NBR (Nitrile Butadiene Rubber, temperature resistance -20℃~120℃)
• Handle: Carbon steel powder coated / Stainless Steel
2. Specification Parameters
• Nominal Diameter: DN15~DN50 (corresponding to 1/2"~2")
• Nominal Pressure: PN16, PN25 (1.6MPa, 2.5MPa)
• Interface Type: Internal Thread (compatible with BSP, NPT and other standard threads)
3. Operating Parameters
• Operating Method: Manual 90° Rotary Handle
• Opening/closing torque: ≤50N・m (small diameter) ~ ≤120N・m (large diameter)
• Operating temperature: -20℃~180℃ (PTFE seal); -20℃~120℃ (NBR seal)
II. Product Advantages
• Excellent Corrosion Resistance: The stainless steel valve body can withstand various media such as water, oil, weak acids, and weak alkalis. The 316 stainless steel material can handle the strong corrosive conditions in the chemical industry, resulting in a long service life.
• Convenient Installation and Maintenance: The threaded interface connects directly to the pipeline without additional accessories; the two-piece structure is easy to disassemble, facilitating the replacement and maintenance of the valve core and seals.
• High Opening and Closing Efficiency: Fully open/close operation can be completed with a 90° rotation. The handle operation is labor-saving and suitable for scenarios requiring frequent manual opening and closing.
• Reliable Sealing Performance: PTFE seals are suitable for most operating conditions, ensuring leak-free sealing and meeting the sealing requirements of medium and low pressure pipelines.
• Low Flow Resistance: When the ball valve core is fully open, the fluid channel is linear, resulting in low pressure loss and no impact on pipeline flow.
III. Product Applications
• Civil Applications: Building water supply and drainage pipelines, tap water inlet pipelines, hot water circulation systems, HVAC pipelines.
• Industrial applications: Chemical raw material transportation pipelines, petroleum product packaging pipelines, pharmaceutical pure water systems, and food and beverage processing pipelines.
• Equipment support: Small pump and valve units, experimental device pipelines, and auxiliary pipelines for hydraulic/lubrication systems of mechanical equipment.
•Other applications: Low-pressure pipelines for wastewater treatment, and pretreatment pipelines for seawater desalination (316 stainless steel).
