Butterfly Valve

"rs" butterfly valves have been used since 1993 and possess many advantages over gate,globe,plug and ball valves in varity of installation,particularly in the larger sizes. Savings in weight,space and cost obvious advantages compared to the traditional valves. Maintenance costs are low since there is minimum number of moving parts and there are no pockets to trap fluids.
The control of butterfl valves is very easy and simple becauce a mere rotation of a qurter of the manoeuvering shaft is required to operate to it. Operation quick and easy because a 90-degree rotation of handle moves the flow control element from the fully closed to the fully opened position.
