Fisher Electric Actuators

The Baumann NV electric control valve series is specifically designed for Baumann sliding-stem control valves. It is used for temperature and humidity control for HVAC (hot and chilled water, steam, glycol, etc.), semiconductor manufacturing (clean rooms, make-up air handlers, recirculation air handlers, humidification, chillers, jackets, and glycol systems) and for many more industrial environments (textiles, food and beverage, and tire manufacturing). Actuator Multi-Function Technology (MFT) provides standard auto calibration and signal select ability at the factory or in the field Valve failure modes available - close, open, and last position Choice of power supply: 24VAC or 24VDC Stem position feedback transmitter available Valve High quality S21800 SST and S31600 SST internal valve trim parts are standard; S41600 trim and PTFE seating options are available Dual stem and plug guiding provides increased stability during plug travel Available equal percentage and linear characterized trims to match process loop dynamics

Baumann MV-1020 and VA-1020 electronic modulating valve actuators feature state-of-the-art stepper motor technology to provide unrestricted, continuous modulation and exacting position control. Performance of these actuators rivals the power of our pneumatic diaphragm sliding-stem designs.   Integral Servo Amplifier/Positioner; AC or DC pulse (optional):Accepts 4-20 mA, 0-5 VDC, or 0-10 VDC input signal as standard; split range 4-12 and 12-20 mA; dry contact closure Wide Ambient Temperature Operating Range: -40 to 65°C (-40 to 150°F) Motor Enclosure: Standard: CSA explosion-proof for Class I, Div 1, Groups C & D; Dust-ignition-proof for Class II, Div 1, Groups E, F, G. Also rated NEMA 4, 7, & 9 (IP65) indoor/outdoor; Optional: Group B and ATEX (for 24VDC & 120/240 VAC only) Excellent Positioning Accuracy: +/- 1% of full range Stepper Motor Technology: Unrestricted continuous modulating duty Fits Baumann 24000 Series sliding-stem valve designs: Baumann 24000 series family of bronze, carbon steel, stainless steel, and special alloy designs Top-Mounted Manual Override: Permits manual operation with loss of power Bui

The Fisher D3 and D4 with easy-Drive electric actuator offer an electric globe valve specifically designed for the rigors of upstream applications. Easy-to-use, low power, solar compatible actuators are directly coupled to field proven D3 and D4 valves to provide reliable field operation with reduced maintenance costs. Field gas usage is eliminated: Electric actuator usage eliminates maintenance arising from wet and dirty field gas. Low Power: 12/24 VDC operation and low quiescent power draw suitable for solar powered installations. Flexible Control: Accepts 4-20mA, 1-5V, single and dual dry contact (on/off mode) and Modbus RTU controls signals. Easy-to-use: Calibration is done by opening and closing the valve - no switches to set or move out of position. Fully Integrated: Valve and actuator are fully assembled and tested for single source reliability.
