The Arveon TSK Synchro Check Valves, which are widely used in waste and drinking water systems to prevent water and flap impacts. Water hammer is caused, among other things, by the use of non-suitable non-return valves. If these do not close at the same time with the standstill of the pressurized water column, the water flows back to the pump, which causes the flap to pop with and a strong impact. This process is prevented by using the Arveon TSK Synchro Check Valves. These adapt very precisely to the liquid flow, whereby minimal backflow can occur. As a result, the check valve does not work and there are no harmful pressure waves. Since there is no backflow, no large amounts of water must be brought to a standstill and the flap can operate independently and fail-safe without hydraulic or pneumatic equipment. The advantages at a glance: Low resistance 100% free flow Little pressure waves in the line Low maintenance and a user-friendly, large inspection opening Horizontal and vertical installation possible Also available in underwater version No oil consumption Low purchase price Locking characteristic adjustable on the outside
