Industrial Stop Check Valve
Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016, is a professional manufacturer dedicated to producing high-quality industrial valves. Our Industrial Stop Check Valve, manufactured in Stainless Steel per the GB/T1855 standard, is engineered for reliable performance in demanding steam and water line applications. This valve combines the functions of a stop valve and a check valve, offering superior flow control and backflow prevention, making it a critical component for system safety and efficiency in various industrial settings.
This valve is designed to meet the rigorous requirements of industrial fluid handling. Key features include:
- Dual Function Design: Acts as both a shut-off (stop) valve and a non-return (check) valve, simplifying piping layouts and reducing the need for multiple components.
- Robust Construction: Made from selected Stainless Steel, providing excellent resistance to corrosion, erosion, and high temperatures, ensuring long service life even in harsh environments involving steam and hot water.
- Precision Manufacturing: Produced in compliance with the GB/T1855 standard, ensuring dimensional accuracy, reliable sealing performance, and consistent quality.
- Enhanced Safety: The check valve function automatically prevents reverse flow, protecting upstream equipment from potential damage caused by backflow.
- Versatile Application: Suitable for a wide range of industrial steam and water systems, including boiler feed lines, steam distribution networks, heating systems, and process water lines.
Detailed technical specifications and configurations are outlined below. Specific parameters like pressure rating and port size can be customized to match your project requirements.

Frequently Asked Questions (FAQ)
-
What is the main purpose of a Stop Check Valve?
It serves two primary purposes: to manually or automatically shut off flow (stop function) and to automatically prevent flow reversal (check function), combining two valve types into one unit. -
Why is Stainless Steel used for this valve?
Stainless Steel offers high resistance to corrosion and scaling, which is common in steam and water applications. It also maintains strength at elevated temperatures, ensuring valve integrity. -
What does "per GB/T1855" mean?
It indicates that the valve is designed and manufactured according to the Chinese national standard GB/T1855, which specifies requirements for certain types of valves, ensuring standardized dimensions, performance, and testing criteria. -
Can this valve be used for other fluids besides steam and water?
While optimized for steam and water, its Stainless Steel construction may suit other non-aggressive liquids or gases. Consult with our engineers for specific fluid compatibility. -
What pressure ratings are available?
Pressure ratings are customizable based on your system requirements. We can produce valves for low, medium, or high-pressure applications upon request. -
How is the valve operated?
The stop valve portion typically uses a handwheel, gearbox, or can be fitted with an actuator for remote operation. The check valve portion operates automatically based on flow direction and pressure. -
Are different connection ends available?
Yes. We can provide flanged ends (raised face or flat face) or threaded ends (like NPT or BSP) according to your piping connection standards. -
What is the typical delivery time?
Delivery time depends on order quantity, customization level, and current production schedule. Standard configurations generally have shorter lead times. Please inquire for an estimated timeline.
