16000 Series Stainless Steel Shielded Gate Valves


The HVA 16000 Series Shielded Gate Valve features a travelling shield that moves with the gate to protect it from debris. These valves are used in extremely aggressive applications where reoccuring down time is not an option. The Shield greatly reduces particulate migration and prolongs the sealing integrity of the gate O-ring. The body material is 304 stainless steel, which can be changed to other high temperature, non corrosive materials for exceptionally aggressive applications. Alternative elastomer O-rings are also available.
