Products

Check valves

Check valves, also called non-return valves, allow fluids to flow in a single direction. You can find them at the outlet of the hydraulic system, where fluid return has to be avoided, no matter whether domestic hot water, air, or industrial, discharge and drainage liquids. Check valves work automatically and according to the difference in pressure between the section upstream and downstream of the stem.

Available types of check valve:

The valves can be spring loaded, disc, ball, wafer disc, double disc wafer, swing, wafer swing and foot flanged according to the closing system. They can be made of AISI 304 and AISI 316 steel, brass, cast iron and plastic. The stainless steel check valves produced by Mondeo – Idria, Small, Glovalve and Floy – guarantee contained load loss and better system efficiency thanks to their special shape.

Check valve applications:

Check valves cover a wide range of applications: working pressures from 6 bar to 350 bar and temperatures from -25 to +250 °C. Their versatility makes them perfect for various applications. They are suitable for both industrial and domestic use, in water and industrial liquid treatment plants, in pump groups for civil and industrial water, for compressed air, liquid waste and sewers.

Manifolds

Manifolds are generally used to connect different segments of a hydraulic system, or to connect two pump units to obtain a higher flow rate. Mondeo manifolds are made of stainless steel. Thanks to their slimness, which increases the inner flow surface of the fluid, and TIG-welded threaded parts, load losses are reduced to a minimum. In addition to their optimal hydraulic efficiency, another strong point of our manifolds is that both their size and their configuration can be personalized.

Hydraulic manifold applications:
These manifolds are suitable for transferring domestic hot water, in heating systems, for drinking water. In addition to the plumbing and drainage sector, they are used in water purification systems or for treating industrial water. They can be used in buildings for floor heating, for connecting water meters and for battery connecting water meters. To make pump group assembly easier, kits with the support bases for the pumps, the manifolds, the support for the electric panel, the valves and all the necessary accessories are available.

Pneumatic valves

Motorized valves are ball and butterfly interception valves, with an apparatus that permits remote closing and opening by way of an electric or pneumatic actuator. The pneumatic actuator transmits movement to the valve using compressed air as the movement fluid. Pneumatic actuators can be double or single effect: in the first case it is the air that opens and closes, while in the other case closing is controlled by a spring.

Hydraulic filters

Steel hydraulic filters for water and other liquids

Filters eliminate the impurities in the liquids that circulate inside a hydraulic system. They can be installed at the inlet point and inside the system to prevent the solid particles in suspension from damaging pumps, sensors and measuring instruments. They are available in stainless steel, brass and galvanised steel with diameters from ¼’ to 4’ and larger.
They can be used in both domestic and industrial environments where the maximum pressure reaches 16 bar and the maximum temperature 200 °C.
