Pressure Volume Controller
APPLICATION
• For applications requiring extremely
fine pressure adjustment
FEATURES
• Precisely set a pressure in a closed
pneumatic system
• Pneumatic Volume controller
• Vacuum - 1,000 or 3000psi
• Piston/cylinder device provides fine
adjustment in closed pneumatic
Ashcroft®Pressure Volume Controllers
provide an easy-to-use means of rapidly
and accurately adjusting pressure in a
closed system. These pressure controllers
provide the ability to precisely adjust pressure within 0.00025 psi. When used with
digital pressure gauges, dial gauges,
ransducers, pressure switches, air dead-
t
weight testers, manometers and other similar devices they provide a fast and accurate means for setting a precise pressure.
