As a professional manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance valve engineered to meet the rigorous GB/T1855 standard. This product is designed to provide reliable and long-lasting service in demanding industrial environments where corrosion resistance and durability are critical. With an annual export value between US$1 Million and US$1.5 Million, our products have gained trust across diverse global markets, including North America, Europe, Asia, and Africa. Our commitment to quality, backed by our ISO9001 certification, ensures that every valve delivers consistent performance and value.
This valve is specifically constructed to address the challenges of corrosive media and harsh operating conditions. The application of a high-grade epoxy coating is a cornerstone of its design, providing a robust barrier against chemical attack, moisture, and atmospheric corrosion. This feature significantly extends the valve's service life, reduces maintenance frequency, and lowers the total cost of ownership for your operations. Whether installed in chemical processing plants, water treatment facilities, marine applications, or offshore platforms, this valve offers a dependable solution for controlling the flow of various fluids.
Key Features and Technical Advantages:
- Superior Corrosion Protection: The specialized epoxy coating is uniformly applied and cured to form a dense, inert layer that resists a wide range of acids, alkalis, salts, and solvents, protecting the valve body and internal components.
- Compliance with GB/T1855: Manufactured in strict adherence to the GB/T1855 Chinese national standard, ensuring dimensional accuracy, material specifications, pressure ratings, and performance benchmarks are met for reliable interoperability.
- Extended Service Life: The combination of quality base materials and the protective coating drastically reduces wear from corrosion and erosion, leading to fewer replacements and downtime.
- Versatile Applications: Suitable for use in industries such as petrochemical, power generation, pharmaceutical, food and beverage (with appropriate coating certifications), shipbuilding, and irrigation.
- Reliable Sealing Performance: Engineered with precision-machined sealing surfaces and compatible sealing elements to ensure tight shut-off and minimal leakage, enhancing system efficiency and safety.
- Robust Construction: The valve body is typically crafted from durable materials like ductile iron or carbon steel, providing structural integrity to withstand pipeline stresses and pressure fluctuations.

Frequently Asked Questions (FAQ):
-
Q: What specific advantages does the epoxy coating offer compared to standard paint or galvanization?
A: Epoxy coating provides a more chemically resistant, adherent, and durable barrier. It offers superior protection against a broader spectrum of corrosive chemicals and has excellent adhesion to metal, reducing the risk of coating failure, peeling, or blistering common with standard paints, especially in wet or submerged conditions.
-
Q: Is this valve suitable for potable water applications?
A: While the epoxy coating provides excellent corrosion resistance, suitability for potable water requires specific certifications for the coating material (e.g., NSF/ANSI 61). Please inquire with our sales team regarding available coating options that comply with drinking water standards for your region.
-
Q: Can you provide valves in sizes or pressure ratings not listed in the standard table?
A: Yes, as a manufacturer, we have the capability for customization. We can produce valves in non-standard sizes, higher pressure classes, or with specific material grades upon request. Please share your detailed specifications for a tailored quotation.
-
Q: What does the 12-month warranty cover?
A: Our warranty covers defects in materials and workmanship under normal use and service conditions as specified. It includes repair or replacement of the faulty valve. The warranty period starts from the date of shipment. Specific terms and conditions are provided with the commercial documentation.
-
Q: How does compliance with GB/T1855 benefit international buyers outside China?
A: GB/T1855 is a recognized standard that defines precise technical requirements. Compliance ensures the valve has predictable dimensions, performance, and material properties, facilitating easy integration into systems and providing a reliable benchmark for quality. It is often accepted or referenced in international projects, especially those with Chinese equipment or engineering involvement.
-
Q: What is your typical lead time for an order of these valves?
A: Lead time depends on the order quantity, specific size, and configuration. For standard sizes and configurations, we generally maintain stock for faster delivery. For large or customized orders, a production schedule will be confirmed upon order placement. Our multiple port options allow for flexible logistics planning.
-
Q: Are test reports or certifications provided with the shipment?
A: Yes, we can provide standard factory test reports (such as shell test, seat test) upon request. Our company holds ISO9001 certification, which governs our quality assurance processes. Specific product certifications for the coating can be discussed based on your project requirements.
-
Q: What steps should I take for proper installation and maintenance to maximize the valve's life?
A: We recommend following standard piping installation practices, ensuring proper support and alignment to avoid stress. Avoid mechanical damage to the epoxy coating during handling. Regular visual inspection for any coating damage and periodic operational checks are advised. Detailed installation and maintenance manuals are available.
