Digital electropneumatic positioner for integrated mounting on process control valves

Compact positioner for integrated mounting on pneumatically controlled process control valves. The set-point value setting default occurs via standard signal 4 - 20 mA and/or via AS interface. A sensor element with contactless function records the valve spindle position. Simple start-up via aut

2/2 way diaphragm valve with pneumatic position- actuator (Type Classic)

The externally controlled diaphragm valves, Type 2730 and 2731, consist of a pneumatically operated piston actuator, a built-in positioner, a diaphragm and a 2 way valve housing. The proven and robust actuator with plastic housing ensures use under hygienic or aggressive environmental condition

2/2-way Bellow Control Valve

The bellow control valve is a pneumatically operated process valve with a single-acting diaphragm actuator. A PTFE bellow ensures the separation between medium and actuator. The materials used and the design of the media space allow the use under hygienic or aggressive conditions. It has a good

Adapters for hygienic process valves

Optimised for hygienic process technology in the beverage, food and pharmaceutical industry, control heads, positioners and process controllers can be combined with all types of pneumatically actuated process valves. In terms of automation concept and field equipment selection this enables comp

Low Cost, Low Noise, CMOS Rail-to-Rail Output Operational Amplifiers

GENERAL DESCRIPTION The AD8691, AD8692, and AD8694 are low cost, single, dual, and quad rail-to-rail output, single-supply amplifiers featuring low offset and input voltages, low current noise, and wide signal bandwidth. The combination of low offset, low noise, very low input bias currents, and
