Product Description

Product Specifications
Valve Type: Wafer check valve Structure: Double disc
Standard: BS5153 Workmanship: Investment casting
Sealing direction: Single-directional Sealing grade: Zero leakage
Temperature: -20°C < T < 120°C Operation: Self-starting
Characteristics
Adopting a clamp type structure, it can be directly clamped between two pipeline flanges without the need for additional long-distance installation space. Compared with flange connected check valves, it greatly reduces the overall space occupied by the pipeline system, especially suitable for narrow installation conditions.
Wafer Check Valve Characteristics
Key Advantages
01
Low Fluid Resistance
The valve body flow channel is designed with a streamlined approach. The lightweight valve disc requires minimal medium thrust for opening, reducing turbulence loss and energy consumption of power equipment.
02
Sensitive Opening & Closing
Relying on medium pressure difference for automatic operation. Fast response prevents backflow and effectively avoids water hammer impact damage to equipment.
03
Stable Sealing Performance
Utilizes elastic materials (NBR, FKM) or metal hard seals. Dual seal designs adapt to various media, achieving zero leakage in both low and high-pressure conditions.
Wafer Check Valve Advantage
Packaging & Export
Standard export wooden case packaging ensures safety during international transportation.
Packaging
Application Scenarios
Widely used in pipeline systems in industries such as water supply, sewage treatment, fire protection, petroleum, chemical, power, metallurgy, etc.

Frequently Asked Questions
What is a wafer check valve and how does it work?
A wafer check valve is a type of non-return valve that uses a clamp-type structure to fit between two pipeline flanges. It operates automatically using the pressure difference of the flowing medium — opening with forward flow and closing immediately when backflow is detected.
What standard does this wafer check valve comply with?
This wafer check valve is manufactured in compliance with the BS5153 standard, ensuring consistent quality, dimensional accuracy, and reliable performance across industrial pipeline applications.
What is the operating temperature range?
The valve is designed to operate within a temperature range of -20°C to 120°C, making it suitable for water, sewage, petroleum products, and chemical fluids within this range.
What industries are these valves commonly used in?
They are widely applied in water supply, sewage treatment, fire protection, petroleum refining, chemical processing, and power generation, especially where installation space is limited.
What sealing materials are used in this valve?
Seats are typically made from elastic materials like nitrile rubber (NBR) or fluororubber (FKM), or metal hard sealing structures, often achieving zero leakage performance.
How is the valve packaged for export?
All valves are packaged in standard export wooden cases, designed to protect the products during international shipping and meet global handling requirements.
