Middle and low pressure valves The standard line of VAPTECH Butterfly valves cover a diameter range from 300 to 1400 mm and pressure ratings pf 6, 10, 16 and 25 bar. The standard valve actuation is realized with a hydraulic cylinder and is closed by counter weight. Outside of VAPTECHs’ standard product, butterfly valves are developed with specific pressure ratings of up to 40 bar and diameter up to 5000 mm. Depending on the relation between the inlet diameter, pressure and water speed, the rotor is designed as a disk or as a lattice. The valve function can be alternatively realized with a double acting hydraulic cylinder, an electrical actuator or manualy with a hand-wheel. Additionally the valve can be equipped with upstream and downstream pipes, bypass systems, hydraulic pressure units, aerating - deaerating devices, penstock rupture devices, and digital control systems.
