Introduction

This standard is based on the development of household and similar bistable solenoid valve R & D and production requirements for household and similar purposes bistable The basic standard detection methods state solenoid valve products. Bistable solenoid valve is a refrigerator refrigeration system for controlling fluid flow of refrigerant and off Important parts of the switch. Energy saving refrigeration machine is more commonly used key components, its performance directly affects the relative performance of the machine. General detection methods covered by this standard bistable solenoid valve, through the standard indicators of the performance component testing methods, such independence Li parts can be unified product testing, product certification to promote the unity of the supervision and quality control methods, in line with our actual production, Help standardize and improve the quality of the production and testing. Household and similar bistable solenoid valve Universal Detection
