Safety couplings

	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:		1400 l/min
