discharging and dosing
The TS cycle lock (photo) is used
whenever the discharge from silos,
weighing containers, filter systems or
big bags and the feeding into downstream
production processes, such
as vacuum reactors, screening machines,
mixers or packaging systems,
cannot be realized with standard
valves. The TS cycle lock is available
with nominal diameters from DN 50
to DN 1200. Its chamber volume,
as well as the geometry of the filling
pipe, can be customized. Installation
is simple. As a rule, it is sufficient to
connect the TS cycle lock to the vessel
or the pipeline. Capacitive sensors
or, for simpler media, vibrating-rod
limit switches are available for monitoring
the filling level. Furthermore, the
opening of the inlet and outlet valve
can also be time-controlled. TS cycle
locks are gas-tight and ATEX-certified.
They are therefore suitable as a
safe solution for use as passive explosion
decoupling systems with nominal
diameter from DN 50 to DN 600 in
plants with differential pressures of up
to 10 bar. - Ebro Armaturen Gebr.

A butterfly valve designed for
CSP power plants
The Valtek TX3 Molten Salt tripleoffset
butterfly valve (photo) was designed
to provide concentrated solar
power (CSP) plant operators with reliable
performance, tight shut-off and
minimized maintenance in moltensalt
applications. Eliminating leakage
in the demanding conditions required
for thermal energy storage for
industrial processes is a top priority.

reduce
evaporation losses
The Model 12E (photo) and Model
12F weight-loaded pressure/vacuum
relief valves (PVRV) are said to
achieve both superior sealing performance
and industry-leading flowrates,
while allowing users to reach
the required flow with a potentially
smaller-sized valve. The Model 12E
and 12F weight-loaded PVRVs feature
10% overpressure technology
allowing users to set their valves
closer to flowing pressures, minimizing
product losses and maximizing
profit. Made from aluminum, carbon
steel and stainless steel, Models 12E
and 12F are available in sizes from 2
through 12 in. (DN 50-300), in pressure
settings from 0.866 to 41.5 in.

and vacuum settings of 0.803-41.5
in. water column (2.00-103.4 mbars).
Tightness exceeds API 2000 leak
requirements, the company says. -

Position sensors eliminate
failures in valve control
This company's linear variable displacement
transducers (LVDTs) are
designed with an isolation-tube format
(photo) to ensure reliable displacement
feedback of hydraulic/
non-hydraulic pumps and valves.
The isolation tube protects the LVDT
core from pressurized environments
and fluids when the sensor measures
pump flow or valve position
(open/closed). The position sensor
provides electronic feedback as part
of a process control system. In the
isolation-tube configuration, only the
LVDT core lies inside the harsh area
or media. Constructed of metal, the
core can withstand exposure to a variety
of fluids and pressures so that
the chance of LVDT core failure is virtually
nonexistent. With sensor windings
in near ambient conditions, there
is a low risk of unit failure. - NewTek
