As a professional manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding global industries. Our Marine High Pressure Gate Valve, PN64 Rating, is engineered specifically for critical marine and offshore applications where uncompromising performance under extreme pressure is paramount. Built from forged steel for superior strength and integrity, this valve series offers exceptional durability and leak-tight sealing, ensuring the safety and efficiency of your high-pressure piping systems. We combine advanced manufacturing expertise with stringent testing protocols to deliver valves that meet the rigorous standards required by international marine operations.
This valve is designed to handle the challenging conditions found in shipboard service, offshore platforms, and other high-pressure industrial environments. Its robust construction and precise engineering make it an ideal choice for isolating flow in pipelines carrying seawater, fuel oil, lubricating oil, and other demanding media.
Key Features & Technical Advantages:
- Superior Forged Steel Construction: The body and bonnet are forged from high-quality carbon steel or alloy steel, providing enhanced mechanical strength, impact resistance, and reliability compared to cast alternatives. This forging process eliminates internal defects, ensuring a homogeneous structure ideal for high-pressure service.
- High Pressure Integrity (PN64/Class 400): Rated for PN64 pressure nominal (equivalent to ASME Class 400), this valve is built to withstand significant pressure surges and maintain a bubble-tight seal, crucial for safety in marine applications.
- Wide Size & Configuration Range: Available in a comprehensive range from DN15 (1/2") to DN100 (4"), offering flexibility for various pipeline diameters. Standard end connections are flanged to common international standards (ASME, DIN, JIS), with threaded ends available upon request.
- Robust Stem & Disc Assembly: Features a rising stem design with a non-rotating stem for clear visual indication of valve position. The wedge disc is precision-machined and can be supplied in materials like stainless steel or surface-hardened alloys to resist wear, galling, and corrosion.
- Flexible Seating Options: Depending on service conditions, valves can be furnished with resilient seated or metal-to-metal seated designs. This allows optimization for either superior sealing with some compressibility or extreme temperature and pressure tolerance.
- Multiple Actuation Choices: Standard operation is via a handwheel. For larger sizes or high-differential pressure applications, bevel gear operators or electric/pneumatic actuators can be supplied as optional accessories, facilitating remote or automated control.
- Extended Service Life: Critical wear parts are designed for easy replacement, minimizing downtime during maintenance. Proper material selection and hardening treatments on seats and stems enhance longevity even in abrasive or corrosive media.

Frequently Asked Questions (FAQ)
-
Q: What is the primary advantage of a forged steel body over a cast steel body for this valve?
A: Forged steel offers superior mechanical properties, including higher tensile strength, better impact resistance, and a more homogeneous, defect-free grain structure. This makes it the preferred choice for high-pressure, high-integrity applications like marine service where safety is critical. -
Q: Can this PN64 valve be used for services other than marine applications?
A: Absolutely. While designed with marine specifications in mind, this high-pressure gate valve is suitable for any industrial application requiring PN64/Class 400 pressure rating, including power generation, oil & gas processing, chemical plants, and high-pressure water systems. -
Q: Are these valves suitable for cryogenic service or temperatures above 425°C?
A: The standard temperature range is -29°C to 425°C. For cryogenic applications (below -29°C) or higher temperature services, special material selections, extended bonnet designs, and different sealing arrangements can be provided. Please consult our engineering team for custom requirements. -
Q: What types of flange standards and face finishes do you offer?
A> We typically supply valves with Raised Face (RF) flanges per ASME B16.5 Series A/B, EN1092-1 (PN/DIN), or JIS B2220 standards. Other types like Ring Type Joint (RTJ) or flat face can be manufactured upon request. Surface finish complies with relevant standard specifications. -
Q: Is the valve fire-safe design available?
A: Yes, fire-safe design per API 607/API 6FA standards is available as an option. This includes secondary metal seals that maintain sealing capability in the event of a fire, which is a crucial safety feature for offshore and marine hydrocarbon services. -
Q: Do you provide actuation packages, and can valves be supplied locked in a specific position?
A: We can supply valves equipped with electric or pneumatic actuators from reputable brands or provide a mounting kit for your preferred actuator. Valves can also be supplied with a locking device on the handwheel or gearbox to secure them in the open or closed position as required. -
Q: What is your standard painting/coating for marine environments?
A> Standard external coating is a high-quality epoxy paint suitable for general marine atmosphere. For more severe splash zone or submerged service, specialized coatings like zinc-rich primers, multi-layer epoxy systems, or even rubber lining can be applied. Coating specifications can be customized. -
Q: What documentation and testing reports are provided with the valves?
A> Each valve undergoes rigorous hydrostatic shell and seat tests per API 598. We provide a comprehensive test report, material certificates (3.1 or 3.2 as applicable), and a full set of dimensional drawings. Additional documentation like NDE reports (UT, MPI) can be supplied upon request.
