Product Description
Series A73 & A74 High performance butterfly valves provide cost-effective solution for a wide range of applications where bubble-tight shut-off is required. Utilizing an eccentric disc and offset shaft, the design incorporates the flexible-lip sealing system into a lightweight, compact body. The result is that in many cases the valve can replace globe valve and gate valve with easier operation, longer lasting and lower cost.
Significant performance makes the valve widely used in many applications such as Airport refueling, Hydrocarbon processing, HVAC, Air treatment, Chemical processing, Purified gas, Steam and vacuum services, Potable water, Powder and pulp processing, etc.
