Description

Middle and low pressure valves The standard line of VAPTECH Spherical valves is designed for diameter range from 300 to 1000 mm and pressure ratings 40, 63 and 100 bar. The valve actuation is with a hydraulic cylinder and closing is with a counter weight. The seal of the rotor to the valve body is realized by a movable stainless steel sealing that is actuated through a water-oil pressure system. Outside of VAPTECHs’ standard product, spherical valves are developed with specific pressure ratings of up to 100 bar and diameter up to 3000 mm. The sealing system can be optionally equipped with an additional maintenance seal that, when activated, allows for inspection of the main seal without draining of the penstock water. 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.
