PUMP DESIGN FEATURES

ES-4212 HYDRAULIC CHECK BUTTERFLY VALVE

 

Valve body and flaps are designed to show minimum resistance. Sealing is provided by a tee-section sealing ring, which is circumferentially fixed by the pressure ring on the flap edge. Since the sealing ring of the damper presses the conical machined body seat in the closed position, absolute sealing is provided in both directions. The sealing ring can be easily changed without the need to disassemble the clapper. Since the seat surface is manufactured as hard Chrome or AISI 316 stainless steel weld filler, the seat surface is resistant to wear and corrosion. Our butterfly valves are manufactured as double eccentric. The purpose of the first eccentric is to reduce the pressure on the rubber sealing ring during the opening of the valve, to eliminate the abrasive effect and to obtain a continuous contact between the sealing ring and the body seat. During the opening process of the valve, the rubber sealing ring is easily separated from the body seat surface with the help of the second eccentric. There is a double-piece shaft design that increases the cross section inside the valve. Shaft sealing, on the other hand, provides a longer service life of the valves without the need for maintenance, with the O-ring system made on the self-lubricating bushings made of bronze and delrin. The quarter turn required by the gearboxes butterfly valves.
