产品描述
The Type-2000 Pneumatic and Electro-Pneumatic Valve Positioners are designed to provide stable and accurate control of rotary and linear valves. These force balanced devices are operated with cam characterized air pressure control utilizing a low friction spool valve to accurately drive rotary and linear pneumatic actuators.
Pilot operated, multi-stage 1:1 relay with positive and negative biasing adjustment capability.
Reliability for fail in place applications of control valves when air supply drops below acceptable pressure levels.
Utilizes a signal pressure to produce an output pressure with high flow capacity, that can be amplified. Signal to output ratio's available include 1:1, 1:2, 1:3 and 1:6.
Signal operated regulator that provides an output pressure that is the sum of the input signal pressure plus a preset adjustable bias. Used to convert a low flow signal to the higher flow (up to 50 scfm) requirements of an operating system.
High flow capacity in a rugged casing.
Rapid Stroke Capability in a Rugged Aluminum or Stainless Steel Casing.
Trips to vent one control signal while simultaneously locking up another.
Automatically selects the higher or lower of two input signals.
Combines a Mite 70 with a precision 3-way valve
Compact unit that supplies precise air pressure regulation for applications where space is limited. This unit allows large regulator performance in a small package.
