| D400
– Valve Accessories and Controls
is pleased to announce the release of our D400 Digital
positioner. The D400 is a low air consumption digital
positioner that uses the combination of an I/P and
poppet valves to achieve its accurate control. The
D400 is a microprocessor based, “intelligent”
positioner that can be mounted to rotary or linear
pneumatic actuators for accurate positioner control.
It is available in standard 4 to 20mA, Hart, Profibus
PA, and Foundation Fieldbus; and the different housings
offer the right hazardous area classification that
are required. Please give us a call for an accurate
quote. |

DAMPER
CONTROL – In the previous
Product News from VAC we discussed damper control,
in doing so we thought it would be a good idea to
offer the V100 with a special damper control option.
The damper control option is basically a restriction
in the spool valve, and since speed is not a critical
component to damper control, this will help but
not solve issues due to isolation or hunting. Actuator
sizing is critical in providing good control. Typical
sizing is often increased as much as 3Xs due to
the unusual operating conditions. |

| V200
– A friendly reminder that
the V200 is available in Explosion Proof. The same
Control Air I/P is used and mounted with a bracket
from the V200, all the air is passed inside the
V200 so an extra supply to the I/P is NOT needed.
Check out more information about the V200 at www.vacaccessories.com/v200html.

| Price
Increase – After six years
of working hard to maintain our initial price, we
will have a price increase after the first of the
year. While this is never good news, we have all
been associated with what is happening in our industry
and across industry in general. Raw material prices
from stainless to aluminum and even soft goods (o-rings-seals,
etc.) have gone up. A few items will increase more
than others, but in general the increase will be
3%. |
