As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and durable marine-grade valves. Our Marine Gate Valve is engineered specifically for demanding shipboard HVAC applications, offering robust performance and long service life in corrosive marine environments. With an annual export value ranging from US$1 million to US$1.5 million, we have established trust with clients across North America, South America, Europe, Asia, Africa, and Oceania, supplying components that meet rigorous international standards.
This valve is designed to provide a tight shut-off for fluids in heating, ventilation, and air conditioning systems onboard vessels. Its construction ensures minimal pressure drop when fully open and reliable isolation when closed, which is critical for system efficiency and maintenance safety.
Key Product Features & Technical Advantages:
- Marine-Grade Construction: Manufactured from high-quality cast steel or stainless steel, the valve body offers superior resistance to saltwater corrosion, ensuring longevity and reliability in harsh offshore conditions.
- Flexible Operation: Available in both manual handwheel and gear-operated configurations. The gear operator provides mechanical advantage, making the valve easier to open and close, especially for larger sizes (DN150, DN200) or in high-pressure systems.
- Wide Size Range: Covers DN80, DN100, DN125, DN150, and DN200, providing a comprehensive solution for various pipeline diameters within shipboard HVAC networks.
- Robust Sealing: Features a metal wedge or a resilient seated design (optional) that ensures a bubble-tight seal, preventing leakage and maintaining system integrity.
- Standard Compliance: Designed and manufactured in accordance with international standards such as ISO, DIN, JIS, and ANSI, facilitating global compatibility and installation.
- Low Maintenance: The simple, robust design requires minimal maintenance. Stainless steel trim options further reduce corrosion and wear.
- Versatile Application: Primarily designed for HVAC systems, it is also suitable for general service isolation in other shipboard piping systems carrying water, oil, or air.

Frequently Asked Questions (FAQ)
-
Q: What is the primary application of this Marine Gate Valve?
A: This valve is specifically designed for shipboard Heating, Ventilation, and Air Conditioning (HVAC) systems. It acts as an isolation valve to control or completely shut off the flow of water or other media within the piping network for maintenance or system control purposes. -
Q: Why are there two operation types (Manual and Gear Operated)?
A: Manual handwheel operation is suitable for smaller sizes (DN80, DN100) and lower differential pressures where operation is easy. Gear operation is recommended for larger valve sizes (DN150, DN200) or in systems with higher pressure, as it provides a mechanical advantage, reducing the required operating torque and making it easier for personnel to operate. -
Q: What materials are typically used, and how do I choose?
A: The main body is commonly cast steel (WCB) for general service or stainless steel (CF8/CF8M) for enhanced corrosion resistance. The choice depends on the fluid media and the specific environmental conditions (e.g., high salinity). Our technical team can advise based on your application details. -
Q: Are these valves suitable for other fluids besides water in HVAC systems?
A: Yes, depending on the material selection and seat type, they can handle other compatible fluids such as oil, air, or mild chemicals within the specified temperature and pressure limits. Please consult our specifications for compatibility. -
Q: What standards do your Marine Gate Valves conform to?
A: Our valves are designed to meet common international standards such as ISO, DIN, JIS, and ANSI for dimensions, pressure ratings, and testing. Our manufacturing facility is ISO9001 certified, ensuring consistent quality control. -
Q: Can you provide custom flanges or pressure ratings outside PN16/PN25?
A: Yes, customization is available. We can manufacture valves with different flange standards (e.g., JIS 10K, ANSI 150) and higher pressure ratings upon request. Please provide your detailed requirements for a quote. -
Q: What is the lead time for an order of DN150 valves?
A: Lead times vary based on order quantity, material, and configuration. Standard materials and configurations typically have shorter lead times. We provide accurate delivery estimates upon receipt of your formal inquiry or purchase order. -
Q: Do you offer any warranty or after-sales support?
A: We offer a standard warranty on our products against manufacturing defects. Furthermore, we provide comprehensive after-sales support, including technical documentation, installation guidance, and spare parts availability.
