Swing Check Valves have a disc that is free floating or swings inside the shaft. The swinging of the disc in the forward direction allows for the flow and when closed the disc swings back into place and blocks the reverse flow. The Swing Check Valves Flanged and non flanged are in use. The flanged valves have flanged ends that can connect to flanged pipe ends. These ensure maximum tightness with the pipes to avoid leakages. There are different types of swing check valves. The Api 6d Swing Check Valves can range in size from 2 inches to 24 inches and more. Based on the application requirements the material grade changes as well. The applications include water, wastewater, oil and gas, chemical, food processing and power plant feeder line operations.
Stainless Steel Swing Check Valve
ASTM A351 cf8m wafer Check Valves
A351 CF8 304 inline check valve
The bonnet and disc design allows easy access and maintenance. The steel insert disc is fully vulcanized with special rubber called EPDM. The dimensions vary up to DN300. The Brass Swing Check Valves and other material types are available for different material types to flow through. Depending on the corrosive nature, temperature and pressure of the materials passed through the pipelines. The 3 Brass Swing Check Valves have light weight discs and they require minimum force to open and close. The head loss is also low due to the full bore design.
