VSU - Symmetrical coupling
1 / 8Pagine

Count on our technology... Applications Refuelling and petroleum industry logistics: - Equipment of refuelling vehicles, motor-pumps group, distribution systems and collapsible storage tanks - Fast connection of fuel supply hoses Cooling of: - Electronics - Motors - Water chillers 2 perfectly symmetrical parts The VSU 38 is a symmetrical quick-release coupling. There is therefore no male/female differential on the hoses to be connected as they are fitted with identical mating halves. Hoses can be connected from either end with no risk of error. Quick and simple connection The system of lugs...

... for improved ease of use! A choice of two protective caps • Black metal protective seal cap Leak-tight protective cap that can be used under pressure. With the same locking lugs as the coupling, this protective cap provides a leak-tight seal even if the valve is opened. Shock protection To give this product optimum durability, both parts have a shock protection ring. Totally safe operation • The circuit can only be opened if both parts are connected. • The two parts cannot be disconnected until both valves are closed. Drain function The hose can be drained using the interlock under the...

1. Easy connection Line up the lugs and rotate to connect them. 2. Opening the circuit Turn each valve a quarter turn to lock the connection and open the circuit. 3. Closing the circuit Return the valves to their original positions to unlock the connection and close the circuit. 4. Safe disconnection Simply rotate to release the lugs and separate the two parts. It is now no longer possible to open the circuit. 5. Draining the hose 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. This...

Construction • Metal components: aluminium and stainless steel • Protective ring: Fluorocarbon • Protective caps: - Metal: aluminium and stainless steel - Plastic: POM (Delrin) • A choice of seals: Fluorocarbon (JV) or Fluorosilicone (JS3)
