Product Description

Zhejiang Sanhua LPF Series Electronic Expansion Valve Use in Air Conditioning or Refrigeration Systems or Heat Pumps

Product Description:
LPF series Electronic Expansion Valves are especially designed for use in refrigeration systems. Thanks to the soft-sealing seat design, it can be as tight as a solenoid valve once it is completely shut off thus to prevent liquid refrigerant migrate to evaporator or compressor.

Features: 
• EXTREMELY HIGH INTERNAL TIGHTNESS, WHICH IS AS GOOD AS WITH SOLENOID VALVES(<1ML/MIN) • EQUAL PERCENTAGE FLOW DESIGN FOR BETTER FLOW REGULATION
• SNAP-ON COIL FOR EASIER INSTALLATION
• COIL WITH IP67 WORKS SAFELY IN EXTREMELY ENVIRONMENT

• APPLICABLE FOR OIL-FREE SYSTEM
• BUILT-IN STRAINER AT INLET •FLOWDIRECTION: BI-FLOW
• LPF...D : 60BAR DESIGN FOR R744 APPLICATION
 

GENERAL SPECIFICATIONS
