2.2 Valve description
The spindle valve (non-rotating) can be opened by pneumatic and manual release
mechanism. The release pressure of the pneumatic release mechanism has to be
min. 30 bar up to max. 240 bar.
When using a stick-on lever (to be secured with a safety pin), the valve can be
activated manually.
The valve is equipped with a bursting device (burst pressure acc. to customers'
specification). When using inert gases, the bursting device can be replaced by a
closing plug.
Material: brass, nickel or chrome plating on request
Flow area: 110mm
2
(nominal diameter ø12mm)
Cv value : 3,5m³/h (standard flow rate Qn acc. to ISO 6358)
Cylinder thread: 25E acc. to EN 629-1 or 1“ – 11 ½“ NGT
Outlet: W21,8 x 1/14“ acc. to DIN 477-1 No. 6 for type K85-50.0
W24,32 x 1/14“ acc. to DIN 477 No. 10 for type K85-13.0
Pneumatic cylinder: 2 X G3/8“ (on both sides)
2.3 Working pressure / Test pressure
The nominal working pressure for the extinguishing gases Argon, Argonite, FM200,
Novec 1230 and Inergen 52.40.08 is 200 bar at an ambient temperature of 15°C .
The test pressure of the valves for the mentioned inert gases is 240 bar.
The test pressure of valves for CO2 is depending on the mounted bursting device,
it is max. 250 bar.
Option for installing pressure
gauges or pressure switches
with flat-sealing thread
(torque10-15 Nm)
Please replace o-ring after
every change of the
pressure measuring
device!
!
Caution:
Flat sealing!!
No sealing cone!

2.4 Life cycle
The valves are not subjected to constructive restrictions in their life cycle.
A leak test should be effected at least twice a year.
After each release (in case of fire or test release) the setting screw must be
calibrated with 10 to 11 Nm.
2.5 Handling
Before the valves will be installed on pressure gas cylinders, they have to be handled
and transported with care. Reason for this is to avoid damages of the lever group
and threads (inlet and outlet). A falling down of the valve, that would cause a
damage of the material or even an injury to persons, has to be prevented.
3 Mounting Instruction
3.1 General
Screw the valves into approved steel cylinders with a torque of:
160 to 180 Nm into 25E acc. to EN 629-1
160 to 180 Nm into 1“ – 11 ½“ NGT

3.3 Filling Instruction
1) After the cylinder has been safeguarded against falling down, remove the closing
nut and apply the filling adapter to the outlet thread of the valve. Only now
remove the transport safety device. Slowly open the valve by using the stick-on
lever.
Caution: A cylinder in use still might be filled or might contain residual pressure.
Lift the spindle with a suitable tool slightly from valve seat (picture "B",
detail "D")
Attention: do not lift the spindle through the valve outlet! The valve seat
might get damaged, risk of leakage!
2) Start the filling procedure
3) After finishing the filling procedure close the valve (pic. "C”). Do not adjust the
hexagonal setting-screw unless the valve is completely closed!
4) Put the transport safety device into the bore hole “X” and secure it against slipping
out. This can be done e.g. by using a plombing wire (max.ø 0,5/0,3 DIN1367):
insert plombing wire through bore hole of safety pin, recurve and where
appropriate seal.
5) Calibrate the hexagonal setting-screw with 10 – 11 Nm by using a calibrated
torque wrench.
6) Leakage test in closed position, as shown in pic. "A" (e.g. by means of a leakage
detection spray).
7) Screw on a closing nut (is not necessarily included in the delivery of valves)

Attention: Please make sure that the filled cylinder is equipped with a
closing nut at the valve outlet and a suitable “protection cap
for transport” !
3.4 Initial operation
Secure the filled cylinders in an upright position with an adequate fixing device. The
fixation can be coupled with a weight controlling system.
Attach the outlet tube for the extinguishing agent onto the valve outlet thread.
Attention: the lever must seat on the piston.
If it does not, press down the lever.
Pull out the transport safety pin. In case the safety pin
cannot be pulled out easily (because it is bent) an incorrect
effort to open the valve with mounted safety device has
occurred priliminary.
3.5 Test release
Recommended execution:
Secure the valve type K85-50.0 against accidental opening by a transport safety
device. Remove the outlet tube from the valve outlet connection, close the outlet
connection (thread W21,8 x 1/14") with a suitable closing nut.
Remove the transport safety device.
Charge the pneumatic release device with pressure. Effect the release by the
operation centre or by external pressure.

Attention:
Do not carry out the test release when the transport safety device is inserted!
Please make sure to pull it out before starting the test release!
After the test release and the leak control re-connect the tubes to the valve outlet.
A test release should not be effected more than twice a year.
Calibrate the setting screw after each release with a torque of 10 to 11 Nm.
3.6 Replacement of bursting device
Attention:
Only qualified personnel is allowed to replace the bursting device.
Only use original parts. In case of replacement the new bursting device has to show
the same burst pressure as the previous one.
Mounting instruction:
1) Fit bursting cap (pos. 1) to housing (pos. 2)
2) Screw the housing (pos.2) into the mounting hole of the valve body until it blocks
3) Tighten the screw connection with a torque of 30 – 35 Nm
4) Mount indication disc (pos. 3)
