The patented Hansen Sealed Motor Valve is a unique industrial grade motor operated valve which eliminates the most common concern of other motor operated valves - valve stem seal leakage. The hermetic design has eliminated refrigerant leakage through stem seals because the non-electric rotor is enclosed in a stainless steel can which contains the fluid pressure. The electric stator is located outside the stainless steel can, and is isolated from the fluid in the valve. The outer enclosure provides secondary pressure containment further reducing the potential for refrigerant leaks. The Sealed Motor Valve is unaffected by frost or ice buildup. The V-port or throttling plug is precisely controlled and positioned by the powerful motor. Whether controlling level, temperature or pressure, the Sealed Motor Valve is superior to any valve on the market. The 4-20mA signal allows the customer to control the valve utilizing their own PLC or computer. No proprietary interfaces or controllers are necessary. Available in 7/32" through 4" (5mm through 100mm).

The 32mm Operator angle body valve is the smallest construction of this type, and covers 3/8", " and " pipe sizes. It provides excellent flow and pressure capabilities in an extremely small package.The 8290 Proportional Valve incorporates compact positioner technology to provide you with proportional control of fluids. Available for NC entry under disc, 50mm through .The HS2, 3 and 4 Linear Position Indicators can be supplied with two mechanical or Viper switches and mounts on top of the 8290 valve operator in place of the standard visual indicator. These indicators can be used with the 50mm NC and 63mm thru 125mm NO & NC valves. A wiring box with conduit connections is provided. HS2 and HS3 indicators are suitable for hazardous locations while the HS4 indicator is suitable for non-hazardous locations.Optional ASi and DeviceNet communications are available.
