As a specialized manufacturer with a strong focus on marine applications, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine High Pressure Gate Valve, engineered for PN64 rating. Established in 2016, our commitment to precision and durability is embedded in every valve we produce, supported by our ISO9001-certified quality management system. This valve is specifically designed to meet the rigorous demands of shipboard hydraulic and high-pressure gas systems, offering reliable shut-off performance in critical marine environments. With an annual export value reaching up to US$1.5 million, our products have earned trust across global markets, including North America, Europe, Southeast Asia, and beyond.
Our Marine High Pressure Gate Valve is built to deliver exceptional performance and longevity. Below are its key features and specifications:
- Robust Construction: Manufactured from high-grade carbon steel with optional stainless steel variants, this valve is built to withstand corrosive marine atmospheres and high-pressure surges.
- Superior Sealing: Features a precision-engineered metal-to-metal seat design that ensures a bubble-tight seal, preventing leaks in both hydraulic fluid and high-pressure gas lines.
- High-Pressure Capability: Rated for PN64 (64 bar), it is suitable for the most demanding high-pressure applications onboard ships.
- Versatile Operation: Standard manual operation via a handwheel is provided for easy control. For larger sizes or automated systems, gearbox operation or actuator mounting options are available upon request.
- Wide Size Range: Available in port sizes from DN15 to DN300 (½" to 12"), allowing for integration into various pipeline diameters.
- Temperature Resilience: Operates effectively within a standard temperature range of -20°C to 200°C, suitable for diverse climatic conditions and fluid temperatures.

Frequently Asked Questions (FAQ)
-
Q: Is this gate valve suitable for both hydraulic oil and high-pressure gas?
A: Yes, it is specifically designed for use in ship hydraulic systems and high-pressure gas systems, such as inert gas or compressed air lines, thanks to its metal-to-metal sealing. -
Q: What does PN64 rating mean?
A: PN64 indicates a nominal pressure rating of 64 bar. This valve is designed to safely handle working pressures up to this level at the specified temperature range. -
Q: Can I get this valve in stainless steel?
A: Absolutely. While carbon steel (WCB) is standard, we offer stainless steel (CF8/CF8M) as an optional material for enhanced corrosion resistance. -
Q: Are actuators available for automated operation?
A: Yes. The valve can be furnished with mounting pads for pneumatic or electric actuators. Please specify your automation requirements when inquiring. -
Q: What flange standards do you support?
A: We typically supply valves with standard raised face (RF), ring type joint (RTJ), or flat face (FF) flanges per common standards like ANSI/ASME or DIN. Specific standards can be accommodated. -
Q: What is the lead time for an order?
A: Lead time depends on the size, material, and quantity. For standard configurations in moderate quantities, typical lead time is 4-6 weeks. We provide precise timelines upon order confirmation. -
Q: Do you provide documentation and certifications?
A: Yes. Along with the valve, we provide a material test certificate, product data sheet, and can provide documentation confirming compliance with our ISO9001 QMS. -
Q: What are your main export markets?
A: We export globally, with significant presence in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and across Asia and Europe.
