Please observe the following notes if the
equipment is to be used in explosion-risk areas:
The equipment can be used in zones
(surrounding atmosphere acc. to Directive
1999/92/EC) 0, 1, 2, 20, 21 and 22 (ATEX
Directive 94/9/EC).
The equipment does not have its own potential
source of ignition and is therefore not subject to the
ATEX Directive 94/9/EC.
The equipment is not Ex marked.
Purpose and function
Purpose
The equipment is designed for shutting off
pipelines.
In addition, equipment DN 15 up to DN 100 can
also throttle the flowrate.
Function
The equipment is designed for shutting off
pipelines. For this purpose equipment types DN 125
and DN 150 are fitted with a disk-type plug.
Equipment of size DN 15 up to DN 100 can also
throttle the flowrate. For this purpose the equipment
is fitted with a throttling plug.
By turning the handwheel the stem is lifted or
lowered continuously. As a consequence, the plug
connected to the stem increases or decreases the
flow area.
You can lock the handwheel in the desired position.
The bellows seals off the valve stem.
Even if the bellows seal leaks, the stuffing box will
prevent any fluid from escaping. The stuffing-box
packing is slightly tightened when delivered.
Storing and transporting the
equipment
Attention!
Equipment can be damaged if stored or
transported improperly.
Close all openings with the sealing
plugs or covers supplied with the
equipment or use similar sealing
covers.
Protect the equipment against
moisture and corrosive atmospheres.
Please contact the manufacturer if the
specified transport and/or storage
requirements cannot be met.
