Metal-sealed clapet check valves are one-way operating devices, that is, they prevent the return of pressurized fluid. They find natural use in domestic water systems, water superelevation, firefighting, heating systems, thermal power plants, solar systems, industrial and agricultural water systems in general. Internal hydraulic sealing is carried out by means of the forces exerted by the mass of a tilting plug and the pressure of the liquid above a gasket that implements the seal even at minimal back pressures. Since these valves operate by means of the gravitational force acting on the rocker plug (clapet or clapper), they have no universal characteristic as far as positioning is concerned. The advantage of these valves is the low pressure drop possessed due to the rounded shape of the body and the large cross-sectional area obtained by the swinging of the poppet; these elements also make them very quiet.
Clapet check valves can be installed horizontally or vertically respecting the direction of flow indicated by the arrow stamped on the valve body. In the horizontal position the valve must be installed with the inspection cap facing upward, otherwise the valve cannot operate. In the vertical position, the valve operates only with the upward flow direction. Installation on pipes is done by threads, using normal plumbing practices.
Check the valve periodically, depending on the frequency of use and working conditions. If there are any leaks at the seal, these may be caused by deposits or foreign matter. If this is the case, it is possible to disassemble the inspection cap located on the top of the valve so that the condition of the shutter can be checked and the gasket can be cleaned by removing all impurities with compressed air or mechanical action. This operation can be carried out having previously drained the affected area of the plant.
