PRODUCT DESCRIPTION

The HONGSEN HV Series consists of refrigeration solenoid valves designed for one-way flow control in liquid, suction-gas and hot-gas lines used in refrigeration, cold-storage and air-conditioning systems.

The series includes direct-operated and servo-operated designs. HV3 models are direct-operated and can open with zero pressure differential, while HV8 and larger models use a servo-operated structure and require the specified minimum pressure differential.

SAE flare and ODF solder connection versions are available. Models ending in T identify the ODF solder version. Valve assemblies can be supplied complete with a coil, while valve bodies and compatible coils may also be ordered separately.

Our currently listed valve assemblies are supplied with an AC 220 V coil. Confirm the model, connection size, refrigerant, operating conditions and required coil voltage before ordering.

TECHNICAL SPECIFICATIONS

CONFIRMED MODEL SELECTION

Kv definition: Water flow in m³/h at a pressure differential of 100 kPa and water density of 1 t/m³.

MODEL NOTES

• Models without the T suffix use SAE flare connections.
• Models ending in T use ODF solder connections.
• HV3 models are direct-operated.
• HV8 and larger models are servo-operated.
• The two 1/2-inch ODF models are not duplicates:
  • HV8M4T: Kv 0.80 m³/h
  • HV10M4T: Kv 1.90 m³/h
• Final valve sizing must be based on refrigerant, line function, capacity, temperature and pressure conditions.

APPLICATIONS

• Walk-in coolers and freezer rooms
• Commercial refrigeration systems
• Cold-storage equipment
• Refrigerated warehouses
• Condensing units
• Liquid refrigerant lines
• Suction-gas lines
• Hot-gas lines
• Air-conditioning equipment
