Simply
release pressure

Safe as
a result, easy to use: Spring-return  bunging valves from KIESELMANN can
be precisely and continuously adjusted to the desired  opening pressure.
The valves open and close extremely sensitively even at low differential
pressures.

Our
bunging valves are available in both open and closed versions  with piping
connection. The open design is ideal for free blowing off of CO2. With the closed version,
the excess CO2 can be
collected.

KIESELMANN
bunging valves ensure a constant bung pressure throughout the fermentation
process. They ensure that the required CO2-Saturation is maintained during storage, thus
ensuring consistent quality.

This can
be relied on. This is assured to you by numerous breweries and cider producers,
who already control their processes with the help of our spring-loaded valves.

Bunging
valves in our 6254 and 6255 ranges,  and also the nominal diameters DN 15
and DN 25 in the 6268 range, can also be used as safety valves. However, the
safety function is only possible for the maximum pressure of the respective
setting range. Thus, the use of a bunging valve with the setting range 0.5 -
3.0 bar is permissible as a safety valve with a response pressure of 3.0 bar.
For the setting range 0.2 - 2.2, the response pressure is limited to 2.0. 

• With water seal for detecting gas leaks (optional)

• Small tolerance range

• Use as safety valve only possible to a limited extent

• CO2 return (closed version)

• Suitable for all gases used in the production process

• Type examination for the safety function under the supervision
of TÜV Süd
