Noise Control-
Pulsco Silencers
|
PULSO
blowdown Vent Silencers and Line Silencers provide the
solution to high intensity, broadband noise associated
with pressure relief systems and gas/steam line
turbulence. The PULSCO design reduces low frequency
noise by converting it to high frequency waves through
multiple expansions and contractions pressurized
diffuser and plenum sections. High frequency noise is
then easily absorbed by the acoustic packing in the
tube module.

Noise Control-
Design V260 Control Valves
|
The
Design V260 is a full bore pipeline control valve
designed for optimized pressure and flow control for
ANSI 300 and 600 applications. An integral drilled
attenuator controls noise and vibration from
high-pressure drop liquids and gases. The splined
shaft connection to the actuator eliminates lost
motion allowing for precise control. The Design V260A
with Aerodome attenuator, V260B with Hydrodome, and
V260C Ball Control Valves combine the efficiency of a
rotary valve with the energy-dissipating capability of
a special trim to provide improved performance for
demanding capabilities. The valve is available with
single, dual or dual block-and-speed seal options. The
Design V260 full-bore ball valve is available with
composition or metal seals, and process type stem
packing for improved life. The preferred actuator for
Design V260 is the 1061. The Bettis Scotch Yoke
actuator is used when spring return capability is
needed.
