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.

Operating pressure:

Max. 12 bar

Medium and ambient temperature:

-20 °C to +80 °C

Flow rate:

1900 l/min (at Δp = 0.5 bar)

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!

Locking:

Connection is pressureless; the plug is simply pressed into the coupling.
The sliding nozzle is only accessible when the plug is locked and the unlocking sleeve is pushed back.

Pressure build-up:

Pressure is built up via the sliding sleeve.

Air relief:

The air relief process starts when the sliding sleeve is moved into its home position.

Unlocking:

The plug can be removed by actuating the unlocking sleeve.

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:
1400 l/min
