We are a family-run business producing over the last 50 years exclusively in Italy cast iron gate valves, check valves, foot valves and strainers for the international market.

Our aim is to provide a highly accurate reliable and long-lasting product building long-term trusted relationships with our clients.

For this reason we produce exclusively in Italy and perform rigorous checks on processes and component suppliers, which are all European ISO 9001 certified companies.

We use cast iron and ductile iron castings to produce gate valves, check valves, foot valves and strainers, ranging from DN40 to DN300 and suitable for operating pressures PN 10 and PN 16, in compliance with ISO/EN/ANSI/BS standards.

We are ISO 9001:2015 certified for the design and manufacture of our products, which have the PED Certificate of conformity.

We have achieved important results also thanks to the relationship we have been able to create with the territory in which we operate, strong in unique riches in terms of industrial and artisan traditions, skills and work commitment and, last but not least, the ability to take risks and undertake, expression of a forward-looking and resilient entrepreneurship. This marked vocation to the common good is also the product of our culture. A special relationship with our employees, a direct relationship with the territory and the protection of its natural environment allow us to create special products.

Manufacturing process

Since 1993 the manufacturing process in our plant has been monitored by an integrated and constantly updated hardware/software system.

An internal network of industrial terminals connected to the manufacturing machines allows the supervision of all the production stages and gathers real-time data.

This system allows not only production supervision but also quality control.

Every stage of the checking process, including size measurements, is recorded centrally.

We are therefore able to guarantee the traceability of every manufactured valve, starting from the production batch.

The documentation of every supplied product includes:

chemical analysis and mechanical properties of the materials (with EN 10204-3.1 certification)
inspections of all components upon receipt;
results of the process quality control;
final hydraulic test according to EN 12266-1.

After the assembly stage every valve undergoes the hydraulic leakage test (EN 12266-1), followed by a coating stage, which can be customized.
