Shanghai Zhibang Valve Manufacture Co., Ltd. takes pride in presenting the Zhibang Valve JIS F7305 Marine Globe Valve – a robust and reliable solution for freshwater systems in marine environments. Manufactured from high-quality cast iron with a durable epoxy coating, this valve is specifically designed to comply with Japanese Industrial Standard JIS F7305, ensuring seamless integration into ship piping systems. With a pressure rating of 5K and sizes ranging from DN50 to DN200, our globe valve offers precise flow control for ballast, cooling water, and general freshwater circuits. As an ISO9001-certified manufacturer established in 2016, we combine years of engineering expertise with a commitment to quality, serving customers across North America, Europe, Southeast Asia, and beyond.
Key Features & Technical Specifications
- Compliance with JIS F7305: Manufactured strictly in accordance with the Japanese Industrial Standard for marine globe valves, ensuring dimensional interchangeability and reliable performance.
- Cast Iron Body: High-grade grey cast iron (GG25 equivalent) provides excellent strength, corrosion resistance, and cost-effectiveness for freshwater service.
- Epoxy Coating: A 250-micron fusion-bonded epoxy coating inside and out protects against seawater splashes, humidity, and chemical attack – ideal for marine below-deck applications.
- 5K Pressure Rating: Suitable for low-pressure systems up to 5 kg/cm² (approx. 0.5 MPa) at ambient temperature, commonly used in shipboard freshwater lines.
- Flanged Ends (JIS B2220 5K): Flat-face or raised-face flanges with bolt holes matching JIS B2220 5K pattern, allowing easy bolting to pipe flanges without special adapters.
- Size Range DN50 – DN200: Available in nominal diameters from 2 inches to 8 inches, covering most branch lines and main headers.
- Globe Valve Design: Linear motion disk (plug) guided by a rising stem, offering excellent throttling capability and tight shut-off when fully closed.
- Manual Handwheel Operation: Cast iron handwheel with a comfortable grip – optional chain wheel or gear actuator available upon request for hard-to-reach installations.
- Replaceable Seat Ring: The seat ring is renewable – allows easy maintenance and extends valve service life without replacing the whole body.
- Stainless Steel Stem: 304 stainless steel rising stem resists corrosion and galling, ensuring smooth operation even in humid marine conditions.

Advantages & Customer Benefits
- Corrosion Resistance: The thick epoxy coating and stainless steel stem greatly reduce maintenance intervals in a marine environment – fewer replacements and lower lifecycle cost.
- Precise Flow Control: Globe valve design allows fine throttling of flow, ideal for balancing water lines or regulating cooling water to engines.
- Cost-Effective Material Choice: Cast iron body offers a balanced trade-off between strength and price, especially suitable for freshwater systems where high alloy materials are not necessary.
- Easy Installation: Standard JIS flanges align with existing shipboard piping; bolts and gaskets are readily available.
- Low Leakage Rate: Metal-to-metal sealing with replaceable seat ensures bubble-tight shut-off when new and allows simple refurbishment.
- Customizable Options: We can supply with gearbox, electric actuator, or pneumatic actuator upon request; also available in bronze or stainless steel disc as needed.

Frequently Asked Questions
-
Q: Is this valve suitable for seawater service?
A: This valve is designed for freshwater service. For seawater, we recommend our bronze or nickel-aluminum bronze globe valves with seawater-resistant coatings. Please consult our sales team for appropriate alternatives. -
Q: What is the temperature range of this globe valve?
A: The cast iron body with epoxy coating is suitable for temperatures from -10°C to +120°C for freshwater. For higher temperature applications, please specify when ordering. -
Q: Are the flanges drilled according to JIS B2220 5K?
A: Yes, our flanges are drilled in accordance with JIS B2220 5K standard. The bolt hole pattern and flange facing are as per the standard; please verify your mating flange dimensions. -
Q: Can the valve be supplied with a gearbox or electric actuator?
A: Yes, we offer optional gear-operated and electric actuator configurations for DN80 and above. Please contact us with your torque and control signal requirements. -
Q: What is the lead time for standard sizes?
A: For DN50 to DN100, standard lead time is 15-20 working days. For larger sizes (DN125-DN200), it is 25-30 working days. Rush orders can be arranged upon request. -
Q: Do you provide a test certificate?
A: Yes, a hydrostatic pressure test certificate is included with each valve. Third-party inspection (e.g., Bureau Veritas, DNV, Lloyds) is available at an additional cost – please indicate when ordering. -
Q: Is the epoxy coating FDA approved or potable water safe?
A: The standard epoxy coating is for industrial freshwater applications. For potable water, we offer a food-grade epoxy lining that complies with WRAS or NSF61. Please specify if needed. -
Q: How long is the warranty period?
A: We offer a standard 12-month warranty from the date of shipment against manufacturing defects. Extended warranty up to 24 months is available upon negotiation.
