As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our robust Marine High Pressure Gate Valve, engineered for the demanding environments of ship hydraulic and high-pressure gas systems. Since our establishment in 2016, we have dedicated ourselves to producing reliable flow control solutions for the global marine industry. This PN64-rated valve is a testament to our commitment to quality and performance, designed to ensure safe and efficient operation under extreme pressures.
Our valve is constructed to meet the rigorous standards required for marine applications, offering superior shut-off capabilities and long service life. We understand the critical nature of onboard systems, and our product is built to provide the reliability that ship operators and engineers depend on. With an annual export value reflecting our global reach across markets from North America to Southeast Asia, our valves are trusted worldwide.
The core value of this high-pressure gate valve lies in its ability to maintain a tight seal and withstand the corrosive marine atmosphere, ensuring system integrity and operational safety. It is an essential component for controlling the flow of high-pressure fluids and gases in various shipboard systems.
Detailed Product Features & Technical Specifications:
- Robust Pressure Handling: Specifically designed for a nominal pressure rating of PN64 (64 bar), making it suitable for high-pressure hydraulic circuits and gas systems onboard vessels.
- Durable Construction: Typically manufactured from high-grade cast steel or stainless steel (specific grades available upon request) to resist corrosion from seawater and harsh marine environments.
- Reliable Sealing: Features a metal-to-metal seated design, ensuring a bubble-tight seal even after prolonged use and exposure to high-pressure cycles. This minimizes leakage risks.
- Versatile Operation: Available in standard handwheel operation or with optional gear operation for valves with larger diameters or higher torque requirements, facilitating easier manual control.
- Flexible Connections: Can be supplied with flanged ends (to common standards like ANSI, JIS, DIN) or threaded ends (NPT, BSP) to seamlessly integrate into existing shipboard piping systems.
- Optimized Flow Path: The full-bore design offers minimal flow resistance and pressure drop when fully open, contributing to system efficiency.

Frequently Asked Questions (FAQ):
-
Q: Is this valve suitable for seawater service?
A: The standard materials (like cast steel WCB) offer good general corrosion resistance. For direct, continuous seawater exposure, we recommend specifying stainless steel grades (e.g., CF8M/316) for enhanced protection. Please consult our team for the best material selection based on your specific medium. -
Q: What is the lead time for a typical order?
A: Lead times vary based on order quantity, specific material, and connection requirements. Standard configurations typically have shorter lead times. We provide accurate delivery schedules upon receipt of your detailed inquiry. -
Q: Can you provide valves with different pressure ratings, like PN100 or higher?
A: Yes, our manufacturing capabilities allow us to produce gate valves for a range of pressure classes. PN64 is a common rating, but we can discuss requirements for PN100, Class 600, or other specifications based on your system design. -
Q: Do you offer any actuation options beyond manual operation?
A: Absolutely. While manual operation is standard, we can supply valves prepared for the installation of electric, pneumatic, or hydraulic actuators. Please indicate your automation needs when requesting a quote. -
Q: Are test reports or certifications provided with the valves?
A: Yes, we can provide standard factory test reports (e.g., hydrostatic shell test, seat leak test). Material certificates are available upon request. Our production is governed by an ISO9001 quality system. -
Q: What are the main differences between flanged and threaded versions?
A: Flanged valves are typically used for larger pipe sizes and higher-pressure applications where a bolted, gasketed connection is preferred for strength and ease of maintenance. Threaded valves are common for smaller line sizes and offer a compact connection method. Our team can advise on the best choice for your piping layout. -
Q: How do I determine the correct valve size for my application?
A: The valve size (DN/ NPS) should match your pipeline size. Please provide the nominal pipe diameter, required pressure rating, and the fluid/gas type. Our technical support can help verify the suitability and recommend the appropriate size and trim. -
Q: What is your packaging standard for export?
A: Valves are securely packaged in wooden crates or plywood boxes suitable for long-distance ocean freight, with protective coatings to prevent rust during transit. Custom packaging requirements can be accommodated.
