Product Description

Technical Specifications

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

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.

Key Advantages

✔

Flexible and lightweight opening and closing: The friction coefficient between the sphere and the fluoroplastic valve seat is extremely low. The manual drive version only needs to rotate 90° to complete the full close full open switch.

✔

Wear resistance and aging resistance: The fluoroplastic lining layer has good self-lubricating properties. The lining layer is bonded using high-temperature vulcanization technology, with no bubbles or detachment.

✔

Valve body substrate pressure stability: Made of cast steel (WCB) as base material, with high mechanical strength, suitable for nominal pressures of PN10-PN25.

Packing & Applications

Packaging: Standard export wooden case packaging ensures safety during transit.
Application Scenarios: High-end chemical industry, production of fluorine chemicals, fine chemicals, pesticides, and fertilizers.

Frequently Asked Questions

Q1: What media can the fully lined ball valve handle? A: It is designed for highly corrosive media including concentrated hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, strong alkalis, and organic solvents.

Q2: What is the benefit of the fluoroplastic lining? A: The lining eliminates contact between the medium and the metal body, preventing corrosion and providing a low-friction surface for easier operation.

Q3: Can this valve be used for automated systems? A: Yes, large caliber models can be paired with pneumatic or electric actuators to achieve fast response and automated control.

Q4: What is the pressure rating for these valves? A: These valves are suitable for medium and low pressure systems with nominal pressures ranging from PN10 to PN25.

Q5: What is the expected service life of the lining? A: Under conventional corrosive conditions, the high-temperature vulcanized lining layer typically has a service life of 3 to 5 years.

Q6: Is the valve design compliant with international standards? A: Yes, the valve is manufactured according to the BS5351 standard.
