Check Valve
Check Valve Manufacturer in Africa supplying non-return valves for water, oil, gas, power, and industrial systems
Check valves are designed to allow fluid flow in one direction while automatically preventing reverse flow when the flow direction changes. Different closure mechanisms, including swing, wafer, dual-plate and non-slam designs, can be selected according to pipeline configuration and operating conditions. Check Valve Supplier in South Africa offer solutions for pumping stations, water transmission, oil & gas pipelines, power plants, mining systems and industrial process lines.
Check Valve Features
- Automatic closure when reverse flow is detected
- Disc, piston, swing or dual-plate closing mechanisms
- Wafer and flanged configurations
- Low cracking-pressure options for selected designs
- Non-slam designs for reduced pressure surges
- Suitable for horizontal and vertical installations depending on design
- Corrosion-resistant trim options for demanding services
