Applications
Compact, state-of-the-art control valve and actuator system designed to
control a wide range of process liquids, gases, and vapors. Capable of
air supply pressures to 6.0 bar (87 psig), allowing valve shutoff at high
pressure drops. Live-loaded PTFE packing is standard.
easy-e Heavy-duty general service for controlling liquids and gases,
including viscous and other hard-to-handle fluids. UOP applications
