Frequently Asked Questions
What material is used for the valve body and plate?
The valve body is constructed from durable Ductile iron ASTM A536 65-45-12, and the valve plate is made of Ductile iron lining ASTM A536 65-45-12 combined with Rubber for tight sealing.
What is the pressure rating for these connection sizes?
The main connection sizes listed are standardized for a nominal working pressure of PN1.6MPa.
What size range is available in this series?
The valve comes in sizes ranging from DN50 (2 inches) up to DN300 (12 inches) to fit various industrial pipeline configurations.
What materials are used for internal sealing and bearings?
Sealing is reinforced using NBR O-rings (GB819-85 standard), and internal bushes are fabricated from low-friction F4 PTFE.
How are these valves packaged for international delivery?
Valves are properly cleaned, capped, and placed in solid export crates or palletized wraps to ensure safe transportation and corrosion prevention during sea or air transit.
