VSU quick-release couplings

Product catalog summary
Overview: The document provides detailed information about the VSU quick-release couplings, highlighting their features, applications, and technical specifications. These couplings are designed for use in various industries, including refueling and cooling systems.
Key Features:
  • Symmetrical Design: The VSU 38 coupling is symmetrical, eliminating the need for male/female differentiation, allowing connections from either end without error.
  • Quick and Safe Connection: The lug system ensures quick, simple, and secure locking.
  • Full Flow: A spherical valve ensures optimal flow rate and pressure drop ratio.
  • Ergonomic and Lightweight: Made from aluminum, the coupling is lightweight and easy to handle, with a rotating shutoff to prevent stress under pressure.
  • Drain Function: Allows for easy draining of hoses using an interlock mechanism.
  • Shock Protection: Features a shock protection ring for durability.
  • Safety Features: The circuit can only be opened when both parts are connected, and disconnection is only possible when valves are closed.
Applications:
  • Refueling and petroleum industry logistics, including equipment for refueling vehicles and distribution systems.
  • Cooling systems for electronics, motors, and water chillers.
Technical Specifications:
  • Construction materials include aluminum and stainless steel, with options for different seals (Fluorocarbon, Fluorosilicone, EPDM).
  • Nominal diameters available: 25, 38, 50 mm.
  • Maximum allowable pressure: 10 bar.
  • Temperature ranges vary based on seal type, from -32°C to +120°C.
  • Weight varies by model, with coupling weights ranging from 400g to 2400g.
Additional Options:
  • Protective caps with leak-tight seals are available.
  • Visual identification options include blue and red grips.
  • Safety lock options to prevent accidental closure.
Performance and Reliability: The VSU couplings are manufactured with high precision and quality control, ensuring reliability and traceability. They can be supplied with a Certificate of Conformity.
Ordering Information: When ordering, ensure to order pairs of connectors and consider additional options like protective caps and safety features.

Return the valves to their original positions to unlock the connection and close the circuit. Safe disconnection Simply rotate to release the lugs and separate the two parts. It is now no longer possible to open the circuit. Operation valid for both parts, depending on the side chosen for the drain. With the two parts disconnected, simultaneously pull back the interlock under the coupling and operate the valve: the valve opens and the fluid drains out. 1 - Pull the interlock backwards and hold it in this position This operation can be carried out on both parts, depending on the side chosen for...
