COUPLINGS

Erre.Di. Ltd. founded in 1961, deals with the production of VR Camlock fittings and hose assembly.

The experience gained in the field, the regular investment and continuous innovation, have enabled us to reach a leading position of trust and prominence on the national and international, aimed at industry, steel, chemical, petrochemical, cement, food manufacturers systems and engineering company.

The effort in recent years, aimed at developing a corporate structure able to ensure production quality standards, has allowed us to obtain quality certifications (ISO 9001, PED, ATEX) certify and confirm that an increasing product reliability.

The business skills, technical and engineering allow us to support our customers choices in deployment and implementation of both large facilities and special needs related to existing facilities and suggested the best solution that ensures the most convenient ratio between price and quality.
 

VR CAMLOCK


OPERATION
The quick connections VR were studied to obtain a quick and safe connection between two pipes: it is sufficient to insert the male part in female in a manner that the border rests on the sealing gasket lodged in the lower part of the female. At this point just lower the eccentric lever and the quick connector is locked.

TECHNICAL
Vr couplings can be supplied threaded, flanged, welded or shank suitable for rubber hoses. The types of threads and flanges are in accordance with Italian and international standards, but if necessary can be built on specific customer requirements.

BALL QUICK COUPLING

"AS" QUICK DISCONNECT COUPLINGS

"AS" quick disconnect coupling are suitable for installation on hydraulic and pneumatic plants.

They have a check valve incorporated both in the adaptor and in the coopler.

When the "AS" in disconnected, the valves are closed. This avoids the leakage of fluids.

RAPID SCREW COUPLING

Rapid screw coupling are made both in Carbon Steel and Stainless Steel (AISI 316)

The standard threaded is BSPP but NPT threaded is available on request.

Gaskets are available in Viton or PTFE.

Generally used for high pressure.

FLAT-FACE COUPLING

The flat face couplings are made to avoid the leakage during the operations of connection and disconnection (no-drop).
For this reason they are mainly used in those applications where the fluid passage is particularly dangerous, fine, or must not come into contact with external agents.

The connection of the two parts, can be done by simply pushing the male part on the female part, while the disconnection happens by retraction of the movable ring placed on the female part.

The standard seals are O-ring on Viton and are assembled on:
- Piston-pin on the female part (which acts as obturator)
- Male part inwardly, in touch with female part during connection
- Female part inwardly, in order to prevent any fluid leakage
- Threaded fittings

Other seals can be fitted on request: NBR, EPDM, Silicone, Karlez, FEP, PTFE.


Diameters: 3/8 "- ½" - ¾ "- 1" - 1 "1/4

Materials: AISI 316

Thread: BSPP standard, others on request NPT, UNF, BSP JIC

Working pressure:
200 bar for 3/8 "
170 bar for ½ "
140 bar for ¾ "and 1"
110 bar for 1 1/4 "

SWIVEL JOINT

The swivel joints are used in systems where is required a torsional rotation between two lines.

TANKWAGEN COUPLING

Non-symmetric coupling, well known as “Tankwagen Coupling”

The coupling of the female and male part is functional by pushing both part of the same size into each other.

Then the locking ring is turned to fix the coupling. This locking ring also prevent loosing through vibration,

These coupling are available in two version:

- International DIN 28450

- Italian Type

The two type are not interchangeable.
 

NO DROP

Connection specific to the chemical industry, which provides a high degree of safety.

The detachment of the coupling halves in conditions of open passage due to mishandling, is impossible, since it can not be detached without the sending automatic closure, and this guarantees the absolute safety.

The limited rotation allows a quick and easy attachment even under difficult maneuver.

For these features is particularly suitable for use in the field of aggressive and polluting and where you want to ensure a safe connection between the tank and pump station.

HAMMER - LUG UNION

They are mainly amploued in "OFF-SHORE" applications, to connect flexible hoses between platform and tank ship. They assure a perfet seal with high pressure and allow a quick and easy disconnection. Hammer-lug unions are available in carbon steel and in stainless steel, in size from 1" up to 12". ...
