Electrical Position Indicators

We offer a wide range ofelectrical position indicators to monitor linear and quarter turn valves. Micro switches or proximity switches are available, depending on the type of device. They enable reliable end position feedback and can be equipped with an optinal field bus connection (e.g. AS-Interface, DeviceNet etc.). The new generation is self-learning. The devices recognize the valve end positions from the manual or automatic end position programming during initialization. There’s no more manual setting of micro switches or proximity switches. For additional product information, visit the manufacturer’s website.

Intelligent Positioners

We offer a range of GEMÜ sposition and process controllers for process automation. The product range includes three-point controllers to control the position of motorized valves, electro-pneumatic positioners for pneumatic valves with quarter turn and linear actuators, as well as industrial controllers for the precise regulation of temperature, pressure, flow and levels. For additional product information, visit the manufacturer’s website.

Actuators

We offer GEMÜ linear and quarter-turn actuators for adaptation to valve bodies from other manufacturers. This allows high-quality valve actuators to be fitted to many butterfly and ball valve bodies using connection flanges according to ISO 5211. There is also a suitable actuator in the range for globe and diaphragm valves. For additional product information, visit the manufacturer’s website.

Pressure Gauges, Transmitters & Sensors

The GEMÜ C30 Hydra-Gauge is equipped with a PFA transmitter and a pressure gauge. The body is made from PFA and can be directly integrated into the pipe system by common flare unions. A PFA double diaphragm prevents contamination of the working medium. Only the PFA body and the PFA diaphragm are wetted. For more product information, visit the manufacturer’s website.

Flow Transmitters

We offer several flow transmitting technologies. GEMÜ 3020 and 3021 turbine flowmeters offer a high degree of accuracy for both inert and corrosive liquid media.  These turbine meters can be configured to offer either pulse or analog feedback, high and low alarms, totalizing and batch function.  GEMÜ 3030 is an insertion magnetic flow meter with many programmable features and is a highly accurate measurement technology. For more product information, visit the manufacturer’s website.

Flow Meters

Variable Area (VA) meters are a cost-effective solution for flow indication of liquids and gases.  The thermoplastic variable area flow meters ensure measurement repeatability with plus or minus 1% of end value and plus or minus 3% measured value.  A wide range of GEMÜ standard and special scales are offered to match your process requirements. For more product information, visit the manufacturer’s website.

Limit Switches and Instrument Sensors

We offer bistable reed switches for GEMÜ variable area flowmeters.  GEMÜ 1251-1252 and 1256-1257 limit switches attach to the dovetail on the side of the flowmeters.  These can be positioned anywhere along the scale to provide reliable minimum and maximum alarm feed back.  GEMÜ 1270-1271 and 1272-1273 instrument sensors provide continuous feedback of the entire scale via reed contacts and 2-wire measuring transducers.
