Butterfly Valves

M&H Butterfly Valves have an innovative and efficient design that offers reliable service with a bubble-tight closure. Our Butterfly Valves are available in both CL150B and CL250B, and they meet or exceed AWWA Standard C-504, latest revision. M&H’s design with the EPDM seat located on the vane and mating with a 316 Stainless Steel Body Ring is time proven, and it assures 100 percent bubble-tight sealing for the life of the valve. In addition, our Traveling Nut Operator has a demonstrated durability that is capable of withstanding an overload input torque of 450 ft-lbs at the full-open or full-closed position without damage to the valve operator.
