As a specialized manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is dedicated to providing robust and reliable fluid control solutions for the global energy sector. Our GB/T Compliant Fuel Oil Gate Valves, available from DN50 to DN200, are engineered specifically for the demanding requirements of fuel oil handling systems. We understand that reliability in fuel transfer and isolation is paramount, which is why each valve is backed by a comprehensive Mill Test Report, ensuring traceability and verified material integrity from the very start of the manufacturing process.
This product line represents our commitment to combining stringent national standards with practical, high-performance design. By choosing our valves, you secure a critical component that offers durable sealing, smooth operation, and enhanced safety for your pipelines, contributing directly to operational efficiency and reduced maintenance downtime.
Core Features & Technical Advantages:
- Precision Engineered for Fuel Oil: The internal components and sealing surfaces are designed to handle the specific viscosity and potential corrosive elements found in various fuel oils, ensuring long-term performance without leakage.
- Full-Bore Design: Provides minimal flow resistance when fully open, allowing for efficient fuel transfer and reducing pressure drop across the valve, which is crucial for pump efficiency.
- Robust Construction: The valve body and gate are typically manufactured from high-grade carbon steel or cast steel, offering excellent mechanical strength and resistance to the pressures encountered in fuel oil systems.
- Reliable Sealing Mechanism: Utilizes a parallel gate or wedge gate design with precision-machined seats (often stainless steel or alloy steel) to achieve a bubble-tight seal in both directions, essential for safe isolation.
- Easy Operation & Maintenance: Designed with an ergonomic handwheel or optional gearbox for easier operation under higher pressures. The design often allows for in-line maintenance, reducing service time and costs.
- Comprehensive Documentation: Each valve is supplied with a Mill Test Report (MTR), providing verified chemical and mechanical properties of the materials used, a critical document for quality assurance and compliance audits.

Frequently Asked Questions (FAQ):
-
Q: What does "GB/T Compliant" mean for my international project?
A: GB/T is the Chinese National Standard system. Compliance ensures the valve is manufactured to a recognized, rigorous set of technical specifications for dimensions, materials, pressure ratings, and testing. It is widely accepted in many global markets, and we provide cross-reference to other standards like ANSI/ASME upon request. -
Q: Is the Mill Test Report (MTR) provided for every single valve?
A: Yes. A material-specific MTR, detailing the chemical composition and mechanical properties (yield strength, tensile strength, etc.) of the primary castings or forgings used, is a standard document provided with each valve or batch, ensuring full traceability. -
Q: Can these valves handle other fluids besides fuel oil?
A: While designed and tested for fuel oil service, the robust construction makes them suitable for other non-corrosive or mildly corrosive liquids (water, oil) in similar pressure and temperature ranges. Consultation for specific media is recommended. -
Q: What are the typical lead times for DN150 and DN200 sizes?
A: Lead times vary based on material selection and order quantity. Generally, standard configurations in carbon steel (WCB) have shorter lead times. We maintain strategic inventory for common sizes to expedite delivery. -
Q: Do you offer valves with different end connections, like threaded ends?
A: Our standard offering for the DN50-DN200 range is flanged connections, which are most common in industrial fuel oil piping. Threaded ends are typically for smaller diameters (below DN50). Special connections can be evaluated as a custom order. -
Q: What is the main advantage of a gate valve over other valve types for fuel isolation?
A: Gate valves offer a straight-through, full-port flow path with very low pressure drop when open. They provide a tight, metal-to-metal seal when closed, making them ideal for infrequent, positive isolation applications rather than frequent throttling. -
Q: Are your manufacturing processes certified?
A: Our production facility operates under an ISO9001 Quality Management System, which governs our design, manufacturing, inspection, and testing processes to ensure consistent product quality. -
Q: What are the main export ports, and how does that benefit shipping?
A: We ship primarily from Shanghai, Guangzhou, Hong Kong, and Beijing. This multi-port flexibility allows us to optimize logistics, choose the most efficient route for your destination, and potentially reduce shipping costs and times.
