AVK RECOIL CHECK VALVE, SINGLE DOOR, DN 350-500, PN 16
Gunmetal Seat Ring, AISI431 Hing Pin, EP250
Variant: 641/11-001 - The recoil check valve is a high performance, fast acting, non-slam check valve used to prevent flow reversal. Mechanical assistance is given by a combination of inertia reduction, concentration of mass and ideal suspension of the moving elements. Hydraulic assistance is given by the novel provision for forward and backward water streams within the body and around the valve door.
