Motor Operated Valve
Model MCV
INTRODUCTION
The Hansen Motorized Control Valve is a truly unique
motor operated valve which eliminates the most common
concern of other motor operated valves—valve stem
seal leakage. 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.
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
Modulating or Slow Open/Close Solenoid Operation
ADDITIONAL FEATURES
• Self Calibrating
• Relay, current, or voltage input for direct
connection to plant PLC or computer.
• All moving parts are sealed so that
frost will not affect operation.
• Tight closing Teflon seat.
• Canned rotor eliminates valve stem seal leakage.
• Controlled opening and closing minimizes
liquid velocity shock, “liquid hammer.”
• Valve is more compact and light weight
than other motor operated valves.
• Same flanges and spacing as Hansen HA4A/
HS4A pressure regulators and solenoid valves.
• Suitable for use with ammonia, R22, R134a,
CO2 (up to 800 psi welded) glycol, water,
brines, and other approved refrigerants.
• Available with optional Power-Backup feature.
• Valve position indicator display included.
• Available with weld-in connections.
