Valves VS 100, VS 110, VS 120 and Two Valve Manifolds VS 200
Isolating valves are used to shut off the supply of pressured
medium to the pressure sensor. In addition, the valve type with
a small deaeration valve (VS 100, VS 120) allows discharge of
mud or deaeration of the impulse piping. VS 120 valve, thanks
to the side screwing, allows connection of other equipment to
pressure medium. Individual types of the valves are designed
for direct installation on a pressure sensor or for installation
between the impulse piping.
The two valve manifold VS 200 is used to shut off the supply
of pressured medium to the pressure sensor, allows discharge
of mud or deaeration of the impulse piping and possibly serves
to connect other equipment to pressure medium. The manifold
is designed for direct installation on a pressure sensor or for
installation between the impulse piping.
3.2 Description
All parts of the valve is made of stainless steel 1.4541 except
the sealing ball and spindle gland. As a sealing element of the
valve is used a ball, embedded into the valve spindle face and
closing the through seat with diameter 4 mm. Material of the
sealing ball is optional; it could be made of quenched stainless
steel 1.4125, ceramics Si3N4 or plastic PTFE 325. The valve
spindle of the standard version is sealed using a FPM (Viton)
or EPDM O-ring; in both cases with two Teflon supporting rings.
In case of valves with gland packing adjuster it is possible to
choose the sealing material PTFE, Graphite or PEEK. The
wide range of dimensions of the input and output screwing
allows installation of the valve into a welded on piece, on a
sleeve with a transition connection, into a sensor screwing or
connection of the impulse piping using a welding on nipple,
welding on plow or single cutting ring for piping diameters 8, 10
mm, or double cutting ring for piping diameters 12 or 14 mm.

4. Installation, operation and maintenanceu
4.1 Installation and commissioning
4.1.1 General
The shut off valve is fixed using a connecting screwing,
between the impulse piping or directly on the pressure
sensor. The impulse piping with diameter 12 or 14 mm
is connected by welding to the plow or nipple, see Fig. 2. To
ensure correct position of the nipple or plow, after installation it
shall be welded together with the shut off valve.
Before installation, the impulse piping shall be cleaned from all
dirt. After welding it shall be disconnected from the manifold
and purged to remove any possible dirt from welding.
Piping with outer diameter 8, 10, 12 or 14 mm can be also
connected by using a cutting ring. The minimum length of the
impulse piping to the first bend shall be 33 mm from the pipe
face. The pipe face shall be cut off perpendicularly and the inner
and outer edges shall be deburred. To prevent penetration of
any possible dirt between the contact surfaces, all part shall be
properly cleaned before installation.
Before connection of the sensor it is recommended to test correctness of connection (welding) of the shut off valve by pressurization of the impulse piping.
When both connections of threaded parts are made of
stainless steel, there is danger of galling (formation of
cold weld). This can also occur during ordinary screwing by hand without using tightening key. If the cold weld is
made, the thread is then damaged and parts are unusable. Before first screwing, it is therefore necessary to check whether
threads are free of impurities (and clean if needed) and then
treat the threads against galling (formation of cold weld) by
appropriate lubricant. For example use paste G-Rapid plus or
Lukosan M11 (in case of connection for oxygen). For tapered
threads is usually used Teflon tape. Threads with silver covered
surface do not have to be lubricated against galling.
4.1.2 Commissioning
After connection or welding of the impulse piping the shut
offvalve is ready for operation.
After installation of a shut off valve into piping it is necessary to
carry out deaeration of the piping. Deaeration for shut off valve
VS 100 and VS 120 can be done by deaeration screw M6. In
another case the deaeration is done by releasing of air bubbles
by knocking on the piping. The whole system can be flooded
by condensate when the thermal circuit is shut down and the
valve is closed.
In case of a leakage of the spindle gland with valve having
gland packing adjuster, the leakage can be eliminated by
tightening the adjuster screw and the lock nut.
4.1.3 Cleaning the manifold
Clogged manifold may be cleaned only if pressure
medium in the impulse piping is completely disconnected.
Before cleaning of a clogged fitting, screw out the small
valve(s) from the basic body. First remove the valve lock
pin, then screw out the valve and clean the interconnection
channels eventually the valve seat. When cleaning the fitting,
pay attention to the seating (sealing) edge of the valve to
prevent its damage.
Before installation of the valve into the fitting body it is
necessary to screw in the valve spindle up to the stop into the
valve body. To improve tightening and sealing of the valve in the
fitting it is recommended to apply a Teflon tape or a liquid Teflon
compound on the seating surface behind the valve threads.
Tighten the valve to 55 Nm and then press in the locking pin.
In case of cleaning of a manifold designed for use with
oxygen, avoid staining of individual parts of the manifold
with grease. The threads and sealing joints may be
lubricated only by a paste approved for use with oxygen.

4.6 Operation and maintenance
The device is attendance- and maintenance-free.
Only in case of a leakage of the spindle gland (version with
gland packing adjuster), the leakage can be eliminated by
tightening the adjuster screw (position 4). Before tightening
the screw loosen the lock nut (position 5). Tightening torque of
gland packing adjuster is 15 Nm. After tightening the adjuster
retighten the lock nut.

5.3 Operation conditions
The manifolds are designed and manufactured for operation
in environment defined by conditions IE36 according to the
standard EN 60721-3-3 and technical regulation PT 500026.
Pressure and temperature characteristics
The operating characteristics of a manifold are given by
pressure and temperature, see Fig. 1. These characteristics
determine conditions for use of the manifold. The operating
variables pressure and temperature are in particular given
by the material used for the basic body, by valve and by
material of sealing elements of the valve seat and spindle.
When selecting material of sealing elements, it is needed to
take into account also condition of the operating fluid and its
corrosiveness with regard to the sealing materials and material
of the manifold. For steam is mostly used sealing of seat by
a steel ball (1.4125) with a graphite gland. A ceramic ball of
Si3N4 is used for corrosive chemicals and a soft ball of PTFE
325 is used for gases. Chemical resistances of gland sealing
materials see Table 1.
