Safety couplings DN 7.6

High-quality, robust and durable, one-hand quick disconnect safety couplings, fully automatic for high flow rates.
The coupling is released in two steps:
Air is relieved from the coupling before it is completely disconnected, to minimise the risk of injury
to the operator from hose ends flying around (whiplash effect).
The effortless connection technique and the reduced noise level during disconnection ensure safe and pleasant working.
The safety version conforms to ISO Standard 4414 and EN 983.

Safety couplings DN 7.4
- Pushbutton type -

High-quality, robust and durable, one-hand quick disconnect safety couplings, fully automatic for high flow rates.
The air is relieved by pressing the pushbutton twice.
When it is pressed for the first time, air is relieved from the coupling but the
plug in the coupling remains locked.
The plug is only disconnected when the pushbutton is pressed for the second time.
The dreaded "whiplash effect" is avoided and the risk of injury to the operator
virtually eliminated.
The safety version conforms to ISO Standard 4414.

Operating pressure Max. 12 bar
Medium and ambient temperature -20°C to +70°C
Flow rate 1800 l/min (at 6 bar with connector fitted)
Housing Aluminium
Pushbutton and valve Hardened, galvanised steel
Valve trim Stainless steel
Fitting Nickel-plated brass
Seal NBR

Safety couplings DN 7.8
Bi-Tec type

Patented safety air relief couplings for gaseous media.
Combination of a sliding valve and a quick disconnect coupling!

Connection is pressureless. Only a low spring force has to be overcome. Pressure only builds up when the blue sleeve is pushed forward. It is impossible to disconnect the hose either intentionally or inadvertently in this position. When the sliding sleeve is moved back into its home position, two things happen: The air is relieved from the hose and the coupling can be disconnected.

Operating pressure:

Max. 20 bar

Medium and ambient temperature:

Max. 100°C

Fitting and valve body:

Nickel-plated brass

Unlocking sleeve:

Hardened, nickel-plated steel

Sliding sleeve:

Anodised aluminium

Springs and ball:

Stainless steel

Seal:

Perbunan
Flow rate (air)
p = 6 bar / Δp = 0.5 bar:
