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

This valve adopts a wafer-type mounting design, which allows it to be directly sandwiched between a pair of pipeline flanges without requiring additional extended installation space. In contrast to flange-connected check valves, this configuration substantially reduces the spatial footprint of the entire piping system, rendering it particularly suitable for narrow or constrained installation environments.

Wafer Check Valve Characteristics
Advantages
Easy Installation
Adopting a clip-on installation method (wafer design), it can be easily installed between two pipeline flanges, saving space, reducing the overall weight of the system, and facilitating installation in narrow spaces.
Good Fluid Performance
The valve disc adopts a lightweight design and is equipped with low friction bearings, offering low opening pressure, low fluid resistance, and smooth flow channels to reduce energy consumption of pumps and compressors.
Excellent Sealing Performance
The double valve disc is precision machined with a smooth sealing surface, forming a double sealing barrier with an elastic valve seat. It closes rapidly when medium flows back to ensure zero leakage.
Check Valve Advantages
Packing & Delivery
Standard export wooden case packaging
Standard Export Packing
Application Scenarios
This valve finds extensive use in pipeline networks for industries ranging from water supply, sewage disposal and fire safety systems to petroleum refining, chemical manufacturing, power engineering and metallurgical operations. It is particularly effective where installation space is restricted.

? Frequently Asked Questions
Q What is a wafer check valve and how does it differ from a flanged one?
A wafer check valve is designed to be sandwiched between two pipeline flanges using bolts. Unlike flanged check valves, the wafer design significantly reduces face-to-face dimensions, saving space and reducing overall system weight.
Q What standards does this valve comply with?
This valve is manufactured in compliance with BS5153, ensuring consistent quality, dimensional accuracy, and reliable performance for international pipeline systems.
Q What is the operating temperature range?
This wafer check valve is rated for operating temperatures between -20°C and 120°C, making it suitable for a wide range of industrial fluid handling applications.
Q How does the double disc design improve sealing?
The double disc structure features precision-machined surfaces and an elastic seat to create a dual sealing barrier. This allows for rapid closure upon flow reversal, preventing backflow effectively.
Q Which industries commonly use this valve?
It is widely used in water supply, sewage treatment, fire protection, petroleum, chemical processing, and power generation, especially where pipeline space is limited.
Q How is the product protected during export shipping?
All valves are packaged in standard export wooden cases to provide robust protection against moisture, impact, and vibration during international transit.
