As a dedicated manufacturer with a strong foothold in the global valve industry since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding marine applications. Our High Temperature Gate Valve is engineered specifically for the critical task of managing heating media within cargo tank systems on vessels, where operational safety and system integrity are paramount. Designed to withstand continuous service at temperatures up to 425°C, this valve ensures precise flow control and secure isolation, contributing to the efficient and safe operation of your vessel's heating circuits.
This valve is a cornerstone for systems that prevent cargo solidification or maintain specific viscosities, commonly used for oil, chemical, and other temperature-sensitive liquid cargos.
Key Features & Technical Advantages:
- Exceptional High-Temperature Resilience: The valve body, gate, and seat are constructed from carefully selected materials such as forged carbon steel (WCB, WCC), stainless steel (CF8, CF8M), or other specialized alloys to maintain structural integrity and sealing performance at the rated 425°C.
- Superior Sealing Performance: Features a metal-to-metal seated design. The precision-machined gate and seat create a bubble-tight seal in the closed position, minimizing leakage even under extreme thermal cycling and pressure differentials.
- Robust & Low-Maintenance Design: The simple yet sturdy gate valve design offers minimal flow resistance when fully open and provides a straight-through flow path, reducing pressure drop. Its design emphasizes durability and ease of maintenance under harsh marine conditions.
- Versatile Operation & Configuration: Available in various configurations to suit different operational requirements and automation levels onboard.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for steam service at 425°C?
A: Yes, it is designed for high-temperature services including steam. However, the specific material grade (e.g., choice between carbon steel and alloy steel) must be selected based on the exact pressure-temperature combination per relevant standards like ASME B16.34. -
Q: Can this valve be supplied with an actuator for remote operation?
A: Absolutely. We offer optional pneumatic (air-to-open/close) or electric actuators. Please specify your required fail-safe mode (spring-return or double-acting) and control signal (on/off, modulating) when inquiring. -
Q: What is the typical delivery lead time for a DN150, PN25 valve?
A: For standard configurations, lead times are generally 4-6 weeks. Customized orders (special materials, actuators, certifications) may require additional time. We provide accurate timelines upon receipt of detailed specifications. -
Q: Do you provide testing certificates with the valves?
A: Yes. Standard delivery includes a manufacturer's test report (shell test, seat test). Additional certifications like NACE MR0175, NORSOK, or specific classification society approvals (ABS, DNV, LR, etc.) are available upon request. -
Q: How does the metal seat perform regarding leakage rates?
A: Our metal-seated gate valves are designed and tested to achieve low leakage rates, typically conforming to API 598 or equivalent standards for metal-seated valves (e.g., Class IV or V). They are suitable for isolation applications where minor leakage is acceptable when closed. -
Q: What maintenance is recommended for these valves in marine service?
A: Recommended maintenance includes periodic operational checks (ensuring smooth opening/closing), visual inspection for external corrosion, and monitoring for any signs of stem packing leakage. The robust design requires minimal intrusive maintenance under normal conditions. -
Q: Are spare parts like gland packing and gaskets readily available?
A: Yes. We maintain an inventory of common spare parts and can supply maintenance kits. We recommend purchasing a set of critical spares with your initial order to minimize vessel downtime. -
Q: Can you customize the valve for a specific pressure class not listed?
A: Yes, customization is a core strength. We can engineer valves for non-standard pressure ratings, special trim materials, extended bonnets, or other unique requirements specific to your cargo tank heating system design.
