Unclouded joy at the Prague zoo
The Prague zoo belongs to the world’s most beautiful animal parks. Through a glass wall in the inner basin, visitors can watch hippopotamuses under water there. An effective water treatment plant ensures unclouded joy and clear water. Eight VAG ZETA® Knife Gate Valves with pneumatic actuators provide help. They were installed in a machine room located below the hippopotamus pavilion. VAG ZETA® Knife Gate Valves seal on both sides and are equipped with an integrated scraper system to ensure perfect leak tightness and reliable function.
