Valve catalogue guide: applications and materials

A guide to choose the right valve

Made in Italy production only

All valves by Maran e Peracini are manufactured in Italy. Our tests and checks on processes and component suppliers are rigorous so that we can provide our customers with valves of Made in Italy highest quality, in a sector where the reliability and the durability of the installed base are critical. Why choose a cast iron valve.

Gate valves

We manufacture cast iron gate valves (grey and spheroidal cast iron, depending on the model) with flat or oval body. They are available in the series PN10 and PN16 with different seal types: brass, bronze, stainless steel, cast iron, rubber wedge.

Check valves

We produce swing check valves PN16 grey in cast iron, with different types of sealing: rubber, brass, bronze, steel.

Our product portfolio includes also:

Foot valves

Made of grey cast iron, PN16, they allow the drainage of particles and the fluid return block function does not need manual action.

Cast iron filters

They are also called impurity collectors; they are PN16, and have a drain plug.

The right resistance

To prevent corrosion the internal surfaces of the valves, which come into contact with the fluids, must be protected with appropriate coating. To have a general indication on the corrosion resistance of the different valves in our catalog with respect to the different fluids, we have created a reference table.

APPLICATIONS

In the plants where our valves are used, excellent quality products because complex installations and difficult access make troubleshooting, extraordinary maintenance and replacements not easy: they could require unplanned plant shutdown and affect operating costs.

The features of our valves make them suitable for applications in multiple sectors:

Food industry (dairies, sugar factories, ...)
Water treatment plants
Waste water plants
Sea water
Saline
Irrigation systems
Heating, air conditioning and refrigeration systems (HVAC)
Fire sprinkler systems
Pulp and paper
Mining and processing of raw materials
Utility systems in industrial plants in general
Tanks
Fuels and transformer oil
Naval sector.

Depending on application, requirements vary in terms of maximum temperature and operating pressure, and of the materials of the different components.

Our catalogue can be browsed by applying the search filters and includes valves suitable for high temperatures (max 150 ° C), PN 10 and PN 16. For each valve a detailed sheet shows all the specific features, fields of application, available variants and compliance with different standards (ISO / EN / ANSI / BS) and PED (Pressure Equipment Directive).
