ENGİNE CONTROLLED DOUBLE ECCENTRIC BUTTERFLY VALVE

ES-4212 HYDRAULIC CHECK BUTTERFLY VALVE

These are products which allow liquid to flow at flow direction and used for preventing flow at reverse direction. It prevents fluid back flow when pump is out of service in pump plants. Ball is closed by its own weight or counter force. Check valves are mounted considering the fluid flow direction. Ball system deforms late with respect to flap system. In the event that it is deformed , upper cover is opened and ball is removed and new one is installed and maintenance of checkvalve is made easily. It can be used easily in drinking water plants and fluids which are free of acid.

These valves have closure system in screen form by means of slide and connected to pipe lines and used for stopping fluid inside pipe. Screwed shaft which is mounted inside housing moves slide up and down and performs open and close operation for valve. Sealing is maintained by gasket which is coated over slide. They are used liquids which do not have abrasive property and in liquid fuel installations. They are not used for controlling and flow adjustment.

Air accumulations which occur particularly in pump outlets when water is delivered to pump outlets and pipe lines and makes water flow area narrower and causes decrease in capacity. Double ball vacuum lifters are used for preventing this adverse issue and in locations where high efficiency is required. Air which occurs when water is delivered to system firstly fills into vacuum lifter and discharged through holes which are located at inner side covers. Then water fills into vacuum lifter and lifts ball up and holes are closed and sealing is maintained.
