Shanghai Zhibang Valve Manufacture Co., Ltd, established in 2016 with an annual export value of US$1–1.5 million, presents our premium Flanged Marine Butterfly Valve with Actuator Pad, DN200 size, specifically designed for engine room auxiliary lines. As a dedicated manufacturer based in Shanghai, China, we leverage ISO9001-certified production to deliver valves that ensure reliable flow control in demanding marine environments. This valve integrates a robust flanged body, a pre-installed actuator mounting pad, and a corrosion-resistant disc, offering a cost-effective solution for seawater, cooling water, and ballast systems commonly found in engine rooms. With over 8 years of export experience to markets across North America, Europe, Southeast Asia, and beyond, we are committed to providing durable, easy-to-install valves that minimize maintenance downtime.

Key Features & Technical Specifications

Flanged Design – Conforms to ISO 7005 / EN 1092 standards, enabling straightforward bolting to pipe flanges without additional gaskets. Suitable for both onshore and offshore engine room piping.
Integrated Actuator Pad – Pre-machined mounting platform according to ISO 5211, allowing easy attachment of pneumatic, electric, or hydraulic actuators. Simplifies automation retrofits for remote control in engine room auxiliary circuits.
DN200 (8 inch) Size – Ideal for medium-flow auxiliary lines such as jacket cooling water, fire main, or fuel oil service. Offers low pressure drop and full unobstructed flow when fully open.
Material Options – Standard ductile iron body (GGG40) with stainless steel disc (CF8M) and EPDM seat. Optional materials like bronze, nickel-aluminum bronze, or PTFE-lined seat are available upon request.
Pressure & Temperature – Rated PN10/PN16 (150 psi max) with operating temperature range -10°C to +120°C. Special high-temperature or cryogenic designs can be customized.
Corrosion Resistance – Fusion-bonded epoxy coating (min. 250 microns) on body and disc, plus vulcanized rubber liner that isolates metal parts from corrosive fluids.

Advantages & Customer Benefits

Space-Saving & Lightweight – Butterfly design reduces overall weight compared to gate or globe valves, critical for engine room space constraints.
Quick Quarter-Turn Operation – Only 90° rotation from fully open to closed, enabling rapid shutdown or throttling in emergency auxiliary lines.
Bubble-Tight Shutoff – Elastomeric seat provides zero-leakage performance at rated pressure, preventing cross-contamination between seawater and fresh water systems.
Easy Actuator Integration – Pre-drilled actuator pad allows direct mounting of pneumatic/electric actuators without additional brackets, reducing installation time and cost.
Reliable in Harsh Marine Environment – Epoxy coating and stainless steel internals resist saltwater corrosion, ensuring long service life in engine room humidity and splash zones.
Customizable Configurations – Available with lever handle, gearbox, or actuator; lockable handle option for safety; various seat materials for different fluid compatibility (fuel, lube oil, seawater).

Frequently Asked Questions

Q: Is this valve suitable for seawater?
A: Yes, the standard EPDM seat and stainless steel disc are excellent for seawater. For higher chloride content, we recommend optional Duplex disc or nickel-aluminum bronze body.
Q: Can I install this valve without an actuator?
A: Absolutely. The actuator pad is a mounting platform; you can operate the valve manually with a lever handle or gearbox (sold separately). The pad allows future automation without replacing the valve.
Q: What is the torque required to operate the actuator?
A: For DN200 at PN16, the breakout torque is typically around 80–120 Nm depending on seat material. Our actuator pad is compatible with ISO 5211 F12 standard; we can provide a torque chart upon request.
Q: Do you offer other flange drilling standards?
A: Yes, we can customize flange drilling to ANSI 150, JIS 10K, or GOST standards. Please specify your requirement when ordering.
Q: What is the delivery time?
A: Standard DN200 valves are usually stocked and can be shipped within 7–10 working days. For custom materials or coatings, lead time is 20–30 days depending on quantity.
Q: How do I maintain this valve in the engine room?
A: Periodic inspection of the seat and disc for wear is recommended every 6 months. If the valve is seldom operated, cycle it fully open/close monthly to prevent seat sticking. The epoxy coating requires no special maintenance.
Q: Is the valve certified for marine classification societies?
A: While we hold ISO9001, we can provide valves with third-party test certificates (e.g., DNV, Lloyds) at additional cost. Contact us for classification-specific requirements.
Q: Can I get a sample before bulk order?
A: Yes, sample orders are welcome. We offer sample production with a lead time of 15 days, and the sample cost is refundable for bulk orders above 50 units.
