FAQ What is the cracking pressure of this Gestra valve?The cracking pressure for Gestra DISCO valves is very low by design to minimize pressure drop. The exact value depends on the installation orientation (horizontal vs. vertical) but is typically in the millibar range. Is this valve suitable for vertical pipeline installation with upward flow?Yes, the spring-assisted design ensures positive closure in any installation position, including vertical pipelines with upward or downward flow. What materials are the main components made from?While specific configurations vary, a common construction for this series is a carbon steel body (P240GH / 1.0460) with stainless steel internals (plate, spring) for durability and corrosion resistance. profideals is not an authorized distributor, reseller, or representative of the products featured on this website.
