OEM One Way Valve Ductile/ Cast Iron Body CF8 Disc Factories, Factory
Product Description
Technical 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
With a wafer-type structure, it can be directly clamped between two pipeline flanges, eliminating the need for extra installation clearance. Compared with flange-end check valves, it significantly minimizes the overall footprint of the piping system, making it ideal for space-restricted applications.
Advantages
Partial clamp check valves are equipped with buffering mechanisms or damping devices, which can reduce the impact force when the valve disc is closed, weaken the influence of water hammer effect, reduce the noise and vibration during valve opening and closing, and protect the safe operation of pipelines and downstream equipment.
The structure has a high degree of modularity, and vulnerable parts such as valve discs and seats can be quickly disassembled and replaced without the need to dismantle the valve as a whole; The inner wall of the flow channel is smooth and not easy to accumulate impurities, making daily cleaning and maintenance convenient and reducing downtime for maintenance.
The valve body can be made of ductile iron, cast steel, stainless steel and other materials. The valve disc and seat can be matched with stainless steel, copper alloy or wear-resistant rubber according to the characteristics of the medium, which can adapt to various working conditions such as water, sewage, oil, acid and alkali media, and meet the anti-corrosion and wear-resistant needs of different industries.
Packing
Standard export wooden case packaging
Application Scenarios
It is widely applied in piping systems across diverse sectors including water supply, wastewater treatment, fire protection, petroleum, chemical processing, power generation and metallurgy, with exceptional adaptability to space-constrained installations.
