A passive isolation valve for
explosion safety
The Ventex Passive Explosion Isolation
Valve (photo) isolates interconnected
equipment to prohibit the propagation
of an explosion. It has a very robust
design that is certified to handle
organic dusts, metal dusts, hybrid
mixtures and gases with one-way or
two-way acting systems. The function
of this passive isolation valve is
very simple. During normal operation,
air flows through the valve and passes
around the poppet on the inside. During
an explosion, the poppet is forced
shut by the explosion pressure wave
and locked into place. This creates a
seal in the process line and effectively
prevents the spread of flames and
pressure. Additionally, there are signaling
devices included on all valves to
indicate an explosion has occurred. -

Modular diaphragm valve with
flexible connection system
The new P600S multi-port valve block
(photo) allows for flexible combination
of standardized single components.
The new modular system therefore
offers advantages regarding procurement
and inventory-keeping, while
simultaneously ensuring achievement
of highly individual actuator travel
and flow paths. P600S is available
in various plastics, as well as stainless
steels. With the plastic series, the
company provides a multi-functional
solution for blending, diverting, draining
or feeding chemically corrosive
media. The modular M-block diaphragm
valve is available in materials
PP-H and PVC, and in nominal sizes
DN 8 to DN 25. Spigots, threaded
sockets and union ends on the basic
body can be adapted to individual requirements
via the flexible connection
system. The stainless-steel series is
suitable for blending, diverting, draining
or feeding demanding media in
the pharmaceutical, biotechnology
and food industries. The modular Mblock
diaphragm valve is available in
various stainless-steel materials, and
in nominal sizes DN 20 to DN 25 -
other versions are available on request.
Spigots, flanges and clamps
on the basic body can be adapted to
individual requirements via the flexible
connection system. - GEMÜ Gebr.

A valve to improve hydraulic
fracturing performance
This company has proven in field trials
that its new V3 valve (photo) significantly
increases performance hours in
high-pressure hydraulic fracturing operations.
GD Redline valves and seats
are designed for maximum performance
and reliability, with the full-open,
bonded design providing optimal flow
efficiency and maximum sealing. The
V3 valve has undergone a complete
redesign to improve metallurgy and
heat treatment resulting in enhanced
wear resistance and strength. During
field trials in the Eagle Ford, Permian
and Marcellus shale plays, increased
performance of up to 46% over the
leading competitor was observed. In
the Permian basin, performance of the
V2 and V3 could be compared, with
an increase in performance of 81%
witnessed. - Gardner Denver High

All types of check valves to
match the application
This company offers a variety of
check valves (photo) to meet the
needs of a given application - from
potable water to abrasive slurries and
corrosive chemicals. A wide range of
metallurgies, seating materials and
accessories are available. The importance
of slamming characteristics,
headloss and maintenance needs
have been taken into consideration
when designing these check valves,
which are highly engineered to provide
long life and trouble-free performance,
the company says. All check
valves are certified NSF/ANSI 61 for
drinking water and NSF/ANSI 372
Lead-Free. - Val-Matic Valve and
