Non Return/Check Valve

Non Return Check Valve are planned and Manufactured allowing to BS1868.Check Valves as usually well-known in the Piping System in all fields are reflected very critical in the situation application. Purpose of Check Valve is to prevent the reverse flow of fluid in situation of failure or sudden shut-down of Piping System.Check valves, or non-return valves, are installed in pipeline systems to allow flow in one direction only.
Swing check valves produce relatively high resistance to flow in the open position, due to the weight of the disc. In addition, they create turbulence, because the flap 'floats' on the fluid str
