Frequently Asked Questions (FAQ):

Q: What is the main advantage of using ductile iron for the valve body?
A: Ductile iron offers higher tensile strength, better impact resistance, and greater durability than standard cast iron. It is less prone to cracking, making it suitable for more demanding applications and ensuring a longer service life.
Q: Can this valve be used for both PN10 and PN16 systems?
A: Yes, this valve is rated for both PN10 (10 bar) and PN16 (16 bar) pressures. It is designed to safely operate within these pressure ranges, providing flexibility for different system requirements.
Q: Is the GB/T3036 standard compatible with international flange standards?
A: The GB/T3036 standard specifies dimensions and performance for butterfly valves in China. Its flange connection dimensions are generally compatible with common international standards like ANSI, DIN, or JIS for the corresponding DN sizes, but verification for specific projects is recommended.
Q: What are the differences between wafer type and lug type connections?
A: Wafer type valves are installed between two flanges using bolts through the flanges. Lug type valves have threaded inserts (lugs) on the valve body, allowing it to be bolted directly to each flange independently, which can be beneficial for end-of-line applications or where one side needs to be disconnected.
Q: What fluids are suitable for the EPDM and NBR seat materials?
A: EPDM is generally suitable for water, hot water, steam, alcohols, and mild chemicals. NBR is often used for oils, fuels, and hydraulic fluids. The standard seat is EPDM; NBR is available as an optional material for specific media.
Q: Can this valve be equipped with an actuator for automated control?
A: Yes, the valve design allows for the attachment of pneumatic or electric actuators. Actuators are available upon request and can be customized to meet your control signal requirements (e.g., on/off, modulating).
Q: What is the typical delivery time for orders?
A: Delivery time depends on order quantity and valve size. Standard sizes are often available for quicker shipment. We ship from multiple ports (Shanghai, Guangzhou, Hongkong, Beijing) to facilitate efficient logistics to our global markets.
Q: Does the manufacturer provide any warranty or after-sales support?
A: As an ISO9001 certified manufacturer, we provide quality assurance for our products. Specific warranty terms and after-sales technical support are available and can be discussed upon inquiry.
