Shanghai Zhibang Valve Manufacture Co., Ltd. (established in 2016) is a professional manufacturer specializing in marine valves. Our Marine Butterfly Valve with Actuator Pad is engineered to meet the rigorous demands of shipbuilding – it is fully customizable per shipyard specification and class rules, ensuring seamless integration into your vessel's piping systems. With an annual export value of US$1–1.5 million, we have supplied thousands of valves to shipyards and offshore projects worldwide, backed by ISO9001 certification.
Why choose our Marine Butterfly Valve? It features a robust design with an integrated actuator pad (ISO5211 standard), allowing easy mounting of various actuators (pneumatic, electric, or hydraulic). This flexibility reduces installation time and simplifies maintenance. Whether you need a valve for ballast water treatment, cooling water, or fire-fighting systems, our product can be tailored to your exact requirements – from material selection to pressure rating, connection type, and coating.
Key Features & Benefits
- Customizable Design: Every valve is manufactured according to the specific shipyard specification and applicable class society rules (e.g., CCS, DNV, ABS, LR, BV, etc.) – just provide your requirements.
- Actuator Pad Ready: Standard mounting pad conforming to ISO5211, pre-drilled and tapped for easy actuator installation. Optional manual override available.
- Material Options: Ductile iron (GJS400-15), cast iron, stainless steel (CF8/CF8M), bronze, and special alloys – suitable for seawater, fresh water, oil, and gas applications.
- High Reliability: Double eccentric or concentric design with PTFE/NBR/EPDM seats provides bubble-tight shut-off, long service life, and low torque operation.
- Corrosion Resistance: Epoxy powder coating (standard 250μm) or specialized marine paint (e.g., Hempel, Jotun) protects against harsh marine environments.
- Full Traceability: Each valve is marked with a unique serial number, material certificates, and pressure test records are provided upon request.
- Global Logistics: Shipped from Shanghai, Guangzhou, Hong Kong, or Beijing ports with professional packing for sea freight.

Frequently Asked Questions (FAQ)
-
Q: Can you manufacture the valve to meet a specific class society rule (e.g., DNV, ABS, CCS)?
A: Yes, our butterfly valves are designed to be customizable per any class rule. Simply specify the class society and required certificates during inquiry. We have experience with ABS, DNV, LR, CCS, BV, RINA, and others. -
Q: What is the actuator pad standard? Do you provide the actuator together?
A: The actuator pad is machined according to ISO5211 (standard) with bolt patterns F07/F10/F12/F14. We can supply the valve with a manual gearbox or pneumatic/electric actuator upon request. The pad can also be customized per your actuator mounting dimensions. -
Q: What materials are available for the valve body and disc for seawater applications?
A: For seawater, we commonly offer ductile iron with epoxy coating, bronze, or nickel-aluminum bronze. Stainless steel (316L or duplex) is also an option. Let us know the working medium and pressure to recommend the best material. -
Q: Do you provide material certificates and pressure test reports?
A: Yes, all our valves are supplied with standard material certificates (EN 10204 3.1) and hydrostatic/pneumatic test reports. Additional NDT (UT, MT, PT) can be arranged at extra cost. -
Q: What is the minimum order quantity (MOQ) for customized valves?
A: Our MOQ is 1 piece for standard sizes (DN50–DN300) with customization. For larger sizes or special alloys, we usually require 2–5 pieces to optimize production. However, we can discuss on a case-by-case basis. -
Q: How long does the customization process take?
A: After receiving your specification and approved drawing, production typically takes 20–35 days for sizes up to DN300, and 35–50 days for larger valves. Rush orders can be expedited with additional charges. -
Q: What packaging do you use for marine transportation?
A: Each valve is individually wrapped in anti-corrosion paper, sealed in a plastic bag, and packed in a plywood case or steel pallet with proper bracing. We also offer fumigation-free wooden crates for international shipping. -
Q: Is there a warranty on your marine butterfly valves?
A: We offer a standard 12-month warranty from the date of shipment, covering manufacturing defects. Extended warranty (up to 24 months) is available upon request. Our after-sales team provides prompt support for any issues.
