Product Description

Valve Type: Flange ball valve Structure: 2PCS type
Standard: BS5351 Workmanship: Investment casting
Sealing Direction: Single-directional Sealing Grade: Zero leakage
Temperature: -20°C < T < 120°C Operation: Handle
Product Characteristics
The fully lined ball valve design structure completely eliminates the contact between the medium and metal, and can withstand almost all strong corrosive media such as concentrated hydrochloric acid, concentrated sulfuric acid, concentrated nitric acid, hydrofluoric acid, strong alkali, strong oxidant, organic solvent, etc. It can even cope with mixed working conditions of multiple corrosive media, and its corrosion resistance performance far exceeds ordinary fluorine lined ball valves and stainless steel ball valves.
Fully Lined Ball Valve Characteristics
Key Advantages
1 Flexible and Lightweight Operation
The friction coefficient between the sphere and the fluoroplastic valve seat is extremely low, and the opening and closing torque is small. The manual drive version only needs to rotate 90° to complete the full close full open switch; Large caliber models paired with pneumatic/electric actuators have fast response times.
2 Durable Lining Layer
The fluoroplastic lining layer has good self-lubricating and wear-resistant properties. Bonded using high-temperature vulcanization technology, it ensures no bubbles or detachment, with a service life of up to 3–5 years under conventional conditions.
3 Pressure Stability
The valve body is made of cast steel (WCB) as the base material, with high mechanical strength and stable flange connection, suitable for nominal pressures of PN10–PN25 in medium and low pressure systems.
