Clearance type butterfly valve

Series - 7100

Series 7100 are basically seatless Butterfly valves. The valves are used For applications where leakage is Acceptable. They require substantially Reduced operating torques due to Absence of seat and therefore remain Very effective for control applications. These valves are well suited for high Temperature and low pressure Applications. They are even suitable For regulating services in high 0 Temperature gas lines up to +800oc
