VAPTECH has delivered three sets of spherical valves DN700 PN42 for a greenfield hydropower project in Himachal Pradesh, India.
Outside of VAPTECH’ 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.
Advantages for the project:
In-house functional (pressure and water) tests
