As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding industrial and marine applications. Our Marine High Pressure Gate Valve, PN64 Rating, is engineered to meet the rigorous challenges of offshore and shipboard environments, offering exceptional sealing performance, durability, and ease of operation under high-pressure conditions. With years of expertise and a commitment to quality, we ensure every valve delivers consistent performance, enhancing the safety and efficiency of your critical piping systems.
This valve is designed for precise isolation in pipelines carrying water, oil, gas, and other media. Its robust construction and high-pressure rating make it an indispensable component for:
- Marine Vessels: Ballast systems, bilge lines, fuel oil lines, and seawater cooling systems.
- Offshore Platforms: Production manifolds, water injection lines, and utility services.
- Industrial Plants: High-pressure steam lines, process water, and other critical services requiring tight shut-off.
Key Features and Technical Advantages:
Our Marine High Pressure Gate Valve incorporates several design features that set it apart from standard valves:
- Rising Stem Design (OS&Y): Provides clear visual indication of the valve position (open or closed), a critical safety feature for marine applications where space is confined and operational status must be instantly verifiable.
- Flanged Connection: Ensures a secure, leak-proof connection to the pipeline, facilitating easy installation, maintenance, and replacement. Flanges are machined to international standards for perfect alignment.
- High-Pressure Integrity: Rated for PN64 (Class 400), the valve body is designed with ample wall thickness and reinforced structures to withstand internal pressures and external loads encountered in marine service.
- Superior Sealing: Features precision-machined wedge and seat rings. Options include metal-to-metal sealing for high-temperature applications or resilient seated designs for bubble-tight shut-off.
- Corrosion Resistance: Available in various material grades, including carbon steel with protective coatings, stainless steel (CF8M/316), and duplex steel, to combat corrosion from seawater and harsh chemicals.
- Multiple Operation Options: Standard handwheel operation is suitable for most applications. For larger sizes or high-torque requirements, bevel gear operators or pneumatic/hydraulic/electric actuators can be fitted.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a rising stem design in a marine gate valve?
A: The rising stem (Outside Screw & Yoke) design provides a clear, visual indication of whether the valve is fully open or closed. This is a critical safety feature in marine environments, allowing crew to quickly verify valve status in tight engine rooms or piping spaces, preventing accidental operation. -
Q: Can this PN64 valve be used for services other than seawater?
A: Absolutely. While designed for marine corrosion resistance, this valve is suitable for a wide range of high-pressure fluids including oil, gas, steam, and process chemicals, provided the selected body and trim materials are compatible with the service media. -
Q: What flange facing types are available?
A: We typically supply valves with Raised Face (RF) flanges as standard. Ring Type Joint (RTJ) flanges are also available upon request to match specific pipeline requirements. -
Q: Is the valve suitable for both above-deck and below-deck installation?
A: Yes. The valve's robust construction and material options (e.g., corrosion-resistant coatings or stainless steel) make it suitable for various shipboard locations. For exposed above-deck installations, specific material and coating selections are recommended to withstand weather and salt spray. -
Q: Do you offer actuated versions of this valve?
A: Yes. The valve can be equipped with pneumatic, hydraulic, or electric actuators for remote or automated operation. We can provide the complete assembly, tested and ready for installation. -
Q: What is your standard delivery time for these valves?
A: For standard sizes and materials, delivery typically takes 4-8 weeks. Lead times for customized orders or large quantities may vary. We provide accurate timelines upon receipt of your detailed inquiry. -
Q: What quality tests are performed on each valve?
A> Every valve undergoes a rigorous battery of tests, including shell test (body strength), seat leak test (sealing performance), and backseat test. Tests are conducted per API 598 or ISO 5208 standards, and certified test reports are available. -
Q: Can you provide valves with specific national standards, like ANSI or JIS?
A: Yes. As an exporter to global markets, we regularly manufacture valves to ANSI/ASME (American), DIN/EN (European), JIS (Japanese), and other international standards. Please specify your required standard when inquiring.
