catalogue contains technical data and notes over valves to the regulation and
shut-off position of liquids, fixed substances, gases and steams. We met in this
catalogue only one selection, can you however at any time a complete
documentation over certain valves and measuring instruments send.
valve can operate satisfyingly only if it were selected on its intended purpose.
Please you address us with technical further inquiries, because we want in a
close contact with you, in order to ensure a satisfying function of the valves.
We give you security that the selected type is really the best and most rational

stop valve, in which the locking off section is taken off by means of a spindle
from the seat or put on these, whereby the spindle axle is located in a right
angle on one level, which is formed by the seat.
the spindle thread on the inside the thread from the other side is
situated to the stem guide within the upper section of the housing, with the external
spindle thread is the thread from the other side in the wall of the upper
normally consist of a symmetrical body with each other opposite links. The
spindle axle forms a right angle with an axle put by both links. With oblique-seated
valves this angle amounts to approx. 45°. With angle valves the
links are to each other in a right angle.
of the stop valves takes place via a screw mechanism with groove by means of
handwheel or drive (electrically, pneumatically, hydraulically)
valve, which the return flow by a setback mechanism prevents. The passage is
opened effected via the current, reasoning with a back-up by the weight of the
mechanism or via a current reversal.
preventing the return flow is used with a check valve around an axle
tiltable hung up flap.
a check valve the setback mechanism is formed by a spring-tensioned plate,
piston or a ball present at an axle.
foot valve is at lower suction tube end and is often equipped with a
filter. The check valve is usually used in pipings, in which by pumps or
gravitation moved media flow.
return flow preventing a diaphragm which is situated on a guidance body
is opened or the return flow is prevented. The selection of the suitable model
or the correct size depends on a number of parameters, like operating pressure,
operating temperature, rate, admissible friction loss etc.. Check valves are
normally used in smaller pipings with diameters to DN 100 and even for higher
shutoff device that permits the free flow of a current. The links are situated
themselves opposite in an axle, which locking off section (wedge or disk) moved
between the seat faces by a spindle, whose axle is situated in a right angle for
flow direction. Slidegate valve gives it in the remarks spindle thread on the
inside and external.
the emergency shut-down slidegate valve, designed for fast opening and
reasoning, the locking off section is moved by lever force by means of a hand
wedge-type slide valve is a shutoff device, with which reasoning takes
place via wedge effect between locking off section and the seats. The wedge
consists of a not flexible material or however with a core of inelastic
the parallel slide valve the locking off section consists two disks of
or. These disks slide between parallel seats, a close termination with the
pressure of the flowing medium are obtained, which firmly presses the disk which
is situated in the diverting direction against your seat. Slidegate valves are
not suitable for throttle functions; they should be quite closed either
completely up or. The one-piece shut-off wedge is substantial executed, can in
operation neither swing nor rattle, so that the wear is small.
valve, which delivers a part of the flowable medium in it automatically outward,
in order to avoid the exceeding of a determined maximum printing. It is used
generally for all media, which make a fast relieving of positive pressure
necessary. In the usual execution the shutting is loaded by directly a feather/spring
sitting on it.
regulations valid after AD specifications require the fact that relief valves
are to be attached at all receivers so that is guaranteed that your highest
design pressure cannot be exceeded. With the full stroke safety valve the
stroke is supported with the escaping pressure. They are fixed adjusted to a
adjustable positive pressure.
which discharge a part of the flowing material automatically, in order to let no
positive pressure develop. It is used generally for not compressable materials (liquids
such as water, oil, etc.). Direct full discharge is not necessary, since already
a small discharge lowers the printing. With directly working overflow valves the
locking off section opens automatically by the direct load on the locking off
section over a feather/spring. Auxiliary controlled overflow valves have max.
flowing through power with full passage, require however when closing or opening
an additional control or control valve. Overflow valves are adjustable. Overflow
valves keep the printing before the valve constant.
valves cause the reduction of a higher form to a constant rear printing. If no
auxiliary energy is needed, then a pressure-reducing valve is called direct
working. Pressure-reducing valves keep the printing behind the valve
device with one perforate ball. By turn of the ball the current can become
released or closed. Ball valves are in such a way designed, which is as small as
possible the friction with the rotation of the ball and an optimal sealing is
ensured in the passage and in the stem guide. The ball to DN 80 mostly is
swimming stored. With a quarter-turn the ball valve is closed or opened. During
full passage the current almost takes place via the cock without resistance.
Under normal conditions the ball valve is not to be used as throttle valve.
shutoff device, whose mobile section consists of a disk, which is swivelling in
axially arranged bearings. Metallically or soft seals can be both in the housing
and on the locking off flap put or let in. Butterfly valves to be able can be
used both for a close termination as well as for gradual throttling (butterfly
valves) or for a combination of these purposes.
stop valve, whose locking off section consists either of a ductile diaphragm or
is enclosed by it. The diaphragm causes the termination and serves at the same
time as seal between the operating mechanism and the flowing through medium. The
diaphragm locks thereby the mechanism of the upper section against the liquid.
Housings and diaphragms are available in a very large area of most diverse
