Acetylene blow-off valve is small and
effective
This special device from Witt Gas has been developed to vent acetylene in combination with manifold pressure regulators as per DIN EN ISO 7291
The direct acting spring-loaded safety valve protects pressure regulators from damage due to excess pressure When the preset opening pressure is reached, the component, which is only 91 mm long, releases excess gas

Stable gas pressure makes for quality applications
The new low pressure regulator from Witt Gasetechnik now makes it possible to obtain industrial quality, maintenance-free oxygen regulators with constant flow in the low pressure part of the range
Control even tiny increases in pressure
Until now, finding a reliable low pressure safety valve (mbar range) has been a problem for operators of gas systems: safety valve type AV619 by Witt-Gasetechnik fills this gap
The valve is available with six different opening pressures of 0.75 to 2.5bar and nominal flow capacities of up to 90m3/hour.
The new Witt valve is particularly easy to install.
This model can be installed in any orientation and is protected from contamination by means of a protective cap.
It is suitable for working temperatures ranging from -40 to +80C.
Importantly, every single unit is inspected and certified by TUV before it is dispatched - a service not many suppliers offer.
In addition to the safety benefits, users will find that this is beneficial if they are seeking to obtain approval for their own machinery.
Witt relies on brass for its housings since brass has a higher resistance in corrosive environments.
The internal compression spring is made of stainless steel, and the valve seal of EPDM.
Both the inlet, with a dimension of G 1/2 male - sealed via an O ring - and the outlet - an M24 x 1 female type bolted connection - are standardised.
Several adapters are available to connect to the vent-off line.
"AV815" is the latest addition to the wide Witt range of safety valves, available for nearly all technical gases, which have been in demand around the world for decades.
As an ISO-certified manufacturer, Witt also produces safety equipment for the protection of individual cylinders, discharge points and pipe systems from gas regression and deflagration.
