Product Specifications
The company offers VR type and quick disconnect couplings for medium and high-pressure applications, available in materials like stainless steel, carbon steel, bronze, aluminum, polypropylene, and hastelloy, with sizes from 1/2” to 8”.
Applications
These products are used in industries such as chemical, petrochemical, pharmaceutical, paper mills, cement factories, and iron metallurgy.
Production Range
The range includes VR quick couplings, rotating splice couplings, 90° revolving couplings, screw couplings, quick disconnect couplings with safety valves, flexible PTFE and metal hoses, dilatation compensators, composite hoses, rubber flexible hoses, and specialized couplings.
Technical Characteristics
VR quick couplings are designed for quick and secure connections, available with threaded, flanged, or welded ends, and comply with Italian and international standards.
Pressure and Temperature Ratings
Pressure ratings vary by size, with smaller sizes rated at 40 kg/cm² and larger sizes at 10 kg/cm². Temperature resistance depends on gasket material, with options like Buna, Dutral, Viton, and PTFE.
Gasket Materials
- BUNA: Suitable for petroleum derivatives, operational from -40°C to 120°C.

Testing and Quality Assurance
Products undergo rigorous testing for reliability and effectiveness, with detailed dimension charts and pressure test results included.
Innovations
New safety systems have been integrated into female couplings to prevent accidental disconnection.
Specifications
Stainless steel (SS316) with surface hardness treatment is available, with various connection types and chemical resistance highlighted.
Materials and Gaskets
A detailed table of chemical resistance for materials and gaskets is provided, including aluminum, bronze, stainless steel, and polypropylene.
PTFE Flexible Hoses
Suitable for transporting chemicals and solvents at high temperatures and pressures, characterized by low friction and high resistance.
Flexible Metal Hoses
Made from stainless steel, these hoses are used in various industries and can withstand temperatures from -269°C to +600°C.
Technical Data
Includes specifications for hose diameters, bending radii, and pressure ratings, noting that burst pressure is four times the maximum working pressure.
Installation Recommendations
Avoid bending hoses beyond minimum radii and prevent torsional stresses during installation and operation.
Axial Tension and Typical Installations
Pipes must be supported to bear weight and avoid external damage. Compression or axial tension should be avoided.
Dilatation Compensators
Metal bellows absorb pipe expansion due to thermal changes, with single-plate and multi-sheet types available.
Composite Hoses
Made from polypropylene and polyester, these hoses are flexible and lightweight, suitable for chemical and varnish industries.

RACCORDI RAPIDI FUNZIONAMENTO Gli attacchi rapidi VR sono stati studiati per ottenere un collegamento rapido e sicuro tra due tubazioni: è sufficiente inserire la parte maschio nella femnina in maniera che il bordo appoggi sulla guarnizione di tenuta alloggiata nella parte inferiore della femmina. A questo punto abbassando le leve eccentriche il raccordo rapido è bloccato. CARATTERISTICHE TECNICHE Le estremità degli attacchi rapidi possono essere fornite filettate, flangiate, a saldare o con codulo idoneo per tubi in gomma. Le filettature e i tipi di flange sono in accordo alle varie norme italiane...

QUICK CONNECTIONS WORKING VR quick couplings have been studied to obtain a quick and safe connection between two lines: it is sufficient to insert the adator into the coupler so that the gasket is in contact with the edge of the adaptor. Now, press the cam levers down and VR is blocked. Tipo E - Maschio per tubi flessibili Type E - Hose shank adaptor TECHNICAL CHARACTERISTICS The ends of VR quick couplings can be independently supplied threaded, flanged, for welding or to be fitted in rubber hoses. Usually threads and flanges are in compliance with the italian and international standards, but...

RACCORDI VALVOLATI A SFERA AS ACCIAIO CARBONIO ATTACCHI RAPIDI A SFERA “AS” Gli attacchi rapidi AS sono particolarmente idonei per installazioni su impianti oleodinamici e pneumatici. La loro particolarità consiste nell’avere incorporata sia nella parte maschio che nella parte femmina una valvola di ritegno. Ne deriva che ad attacco rapido disinnestato le due valvole di ritegno risultano chiuse evitando la fuoriuscita del fluido.
