As a specialized manufacturer with years of experience in the valve industry, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our Fire-Safe Design Single Disc Wedge Gate Valve, engineered specifically for the demanding conditions of offshore applications. This valve is designed to provide reliable shut-off performance even under extreme fire scenarios, a critical requirement for safety and asset protection on offshore platforms, FPSOs, and subsea installations. Our commitment to quality, backed by ISO9001 certification, ensures that every valve meets the stringent standards expected by the global energy sector.
The offshore environment presents unique challenges, including corrosive seawater, high pressures, and the ever-present risk of fire. Our Fire-Safe Gate Valve addresses these challenges head-on with a robust design and carefully selected materials. The core value of this product lies in its dual functionality: providing excellent flow control during normal operations and maintaining a tight seal to prevent catastrophic fluid release in the event of a fire. This capability is not just a feature; it is a fundamental safety requirement for modern offshore operations, helping operators manage risk and comply with international safety regulations.
Key Product Features & Technical Advantages:
- Fire-Safe Design Philosophy: The valve is engineered in compliance with fire-safe testing standards such as API 607 and API 6FA. Key components, including the seat and seal materials, are selected and designed to maintain sealing integrity after exposure to high temperatures, preventing the escalation of a fire event.
- Robust Single Disc Wedge Construction: Utilizing a single disc wedge design provides a strong, uniform sealing force. The wedge is often of a flexible or solid design, allowing it to compensate for minor pipeline misalignments and seat wear, ensuring a bubble-tight shut-off over a long service life.
- Corrosion Resistance for Offshore Use: Materials are specifically chosen to withstand harsh offshore conditions. Standard bodies are typically made from carbon steel with appropriate coatings, while stainless steel (316/316L) or other alloys are available for more corrosive services.
- Versatile End Connections and Pressure Ratings: To integrate seamlessly into various offshore piping systems, the valve is offered with a range of end connections, including raised face (RF) and ring-type joint (RTJ) flanges, as well as butt-weld ends. Pressure ratings cover from ANSI Class 150 up to Class 2500, accommodating diverse system requirements.
- Multiple Operation Methods: Depending on the valve size and application needs, operation can be via a standard handwheel, a bevel gear operator for high-torque applications, or automated with electric, pneumatic, or hydraulic actuators for remote control, which is common in offshore settings.
- Low Maintenance and High Reliability: The simple yet robust design minimizes potential failure points. The rising stem design provides a clear visual indication of the valve position (open or closed), which is crucial for operational safety.

Frequently Asked Questions (FAQ)
-
What exactly does "Fire-Safe Design" mean for this gate valve?
Fire-safe design means the valve is constructed and tested to maintain a seal and prevent leakage of flammable fluids for a specified period (typically 30 minutes) when exposed to direct flame, as per standards like API 607. This involves using specific seat and seal materials that resist burning or maintain sealing force even when softened by heat. -
Why is a single disc wedge preferred for offshore applications over other designs?
The single disc wedge offers a robust and simple design with high structural integrity. It provides excellent sealing force, handles pressure well, and its design is less prone to collecting debris in the seat area compared to some double disc designs, which is advantageous in offshore services where sand or other particulates may be present. -
Can this valve be supplied with actuators for remote operation?
Yes, absolutely. We can provide the valve configured for manual operation (handwheel or gear) or pre-fitted with electric, pneumatic, or hydraulic actuators. Actuator selection depends on available power sources, required fail-safe mode (spring return or double-acting), and control system integration requirements on your platform. -
What materials do you recommend for seawater cooling or injection service?
For seawater or other highly corrosive services common offshore, we typically recommend super duplex stainless steel (e.g., UNS S32750), 6% Molybdenum austenitic stainless steel, or Nickel-Aluminum Bronze (C95800) for both body and trim. Material selection is critical and should be based on a detailed analysis of the service conditions. -
Do you provide documentation like Material Test Reports (MTRs) and Fire Safe Certificates?
We provide full traceability documentation. Material Test Reports (MTRs) for pressure-retaining parts are standard. Formal fire-safe certification from an independent laboratory is available upon request for specific project requirements, though our design is inherently compliant with the relevant API standards. -
What is your lead time for large-size, high-pressure class valves?
Lead times vary based on size, material, pressure class, and order quantity. Standard configurations may have shorter lead times, while customized or large-bore (e.g., 24" and above), high-pressure (Class 1500/2500) valves require more manufacturing time. We provide accurate lead time estimates with every quotation. -
How do you handle painting and coating for offshore corrosion protection?
We apply industry-standard coating systems suitable for offshore C5-M environments. This typically involves abrasive blasting to a specified surface profile (e.g., Sa 2.5) followed by application of a high-performance epoxy primer and topcoat. Specific coating standards (e.g., NORSOK M-501) can be followed upon request. -
Can you supply valves according to specific project standards like NORSOK or DNV?
Yes, we are experienced in manufacturing valves to meet various international and operator-specific standards, including NORSOK (for the Norwegian Continental Shelf), DNV, Shell DEPs, and others. Please provide the detailed standard requirements during the inquiry stage for accurate compliance.
