Motorized Control Valves by HANSEN Technologies

Hansen’s new ¾” thru 2” Motorized Control Valve is a direct motor actuated valve designed for operation in Dx, liquid makeup, temperature, pressure and level control applications.


Description

Hansen’s new ¾” thru 2” Motorized Control Valve is a direct motor actuated valve designed for operation in Dx, liquid makeup, temperature, pressure and level control applications. The Motorized Control Valve has no valve stem seal because the non-electric rotor is enclosed in a stainless steel cartridge, which contains the ­fluid pressure. The electric stator is outside the stainless steel can, and is isolated from the ­fluid in the valve.


Technical Specifications

  • Suitable for use with ammonia, CO2 (up to 800 psi welded) ,water
  • One high-torque motor fits all
  • 3/4"- 2"valves (20 to 50mm)
  • Self-Calibrating: Automatic calibration on power-up
  • Safe Working Pressure:
           -800 psig (SWP) for weld-in-line valves upon request 

           -400 psig (SWP) for flanged valves

  • Max. Operating pressure differential: 800 psid
  • Wide temperature range

           -Ambient: -40°F - 122°F
           -Refrigerant: -75°F - 240°F

  • Low voltage power input 24 Volt AC or DC
  • Various Input Control Signal Choices:0-20 mA, 4-20 mA, 0-5 V, 0-10 V, 1-6 V, and dry contact
  • Built-in Digital Readout 4-20 mA output signal

Advantages

  • Quick and hassle free installation ensured by Factory Set, plug-and-play logic
  • Rugged design delivers highest rated SWP and MOPDProven reliability with over 80,000 hours in the field and 10 years of accelerated life
  • No pressure drop is required to operate
  • Relay, current, or voltage input for direct connection to plant PLC or computer.
  • All moving parts sealed so that frost will not a‑ect operation.
  • Tight closing Te­on seat.
  • Canned rotor eliminates valve stem seal leakage.
  • Controlled opening and closing minimizes liquid velocity shock, “water hammer.”
  • Valve is more compact and light weight than other motor operated valves.
  • Same ­angles and spacing as Hansen HA4A/ HS4A pressure regulators and solenoid valves.
  • Available with optional Power-Backup feature.
  • Available with weld-in connections.
  • The Motorized Control Valve does not require stem shaft

Applications

  • Liquid Make-up to Accumulator
  • Liquid Injection to Compressors
  • DX Evaporators
  • Temperature or Pressure Control
  • Low or High Side Level Control
  • Slow Opening and Closing: Suction Stop Valve
  • No Pressure Drop: Gravity Drain
  • 4-20 mA or Floating Point Control
