Flap damper for clean or charged fluids.
A cost-effective backflow prevention check valve.
Beyond the valve
Flap swing check valves are made as a welded assembly construction and usually used to be installed on end of line and anchored to concrete wall. The design prevents reversal of flow in piping systems, which makes a ideal solution when backflow could potentially cause damage to pumps, filters, or process equipments.
Flange drilling can be made according to customer request or PARAVALVES standard. The seat make direct contact with the disc as an unidirectional or bidirectional design, and can be taylored to fit customer specifications for seat level or design pressures and temperatures.
A compact solution
Designed to prevent backflow.
Our stack damper valves have a lightweight and compact design. As a result, our dampers are particularly suitable for air conditioning systems and industrial ancillary applications, with significant savings in space and investment costs of the installation.
Articulated disc system
To allow or prevent the passage of flow.
Thanks to our hinged disc design, our flap valves do not require actuators for proper operation. The valve uses the force of the fluid to actuate, thus saving on maintenance costs and facilitating installation.
