Non-Return Valves are the special kind of plumbing units that are widely used to allow the flow of the fluid within one direction only. These highly rigid fittings are commonly used in medium to large scale hydraulic systems to prevent the damages due to back pressure to the installations within the system for longer service life. The offered range of Non-Return Valves are available in many different types such as ball and plate type. High quality polyvinylidene difluoride and poly propylene are used for the manufacturing of these component parts which make them capable to withstand impacts of corrosive liquids which includes acid, alkalis and various other solvent.
