JB/T 4119-2013Solenoid valves for refrigeration (English PDF)

Foreword

This Standard is drafted according to the rules specified in GB/T 1.1-2009. This Standard replaces GB/T 4119-1991 "Solenoid Valve For Refrigeration Equipment". Compared with GB/T 4119-1991, main technical changes are as follows.

- Revise the rang of application (see chapter 1, chapter 1 in edition 1991);

- Revise terms and definitions (see chapter 3, chapter 3 in edition 1991);

- Revise the basic parameters of solenoid valve;

- Increase the requirements on dimension, material, appearance, level of protection, high temperature resistance, low temperature resistance, corrosion resistance, cleanliness, noise, breaking strength;

- Revise the requirements on tightness, maximum opening pressure differential, internal leakage rate, insulation resistance, electrical strength, heat and humidity resistance, vibration resistance, durability and flow rate;

- Revise the tightness, maximum opening pressure differential, internal leakage rate, insulation resistance, insulation resistance, electrical strength, heat and humidity resistance, durability and flow rate test method.

1 Scope

This Standard specifies terms and definitions, types, models and basic parameters, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of solenoid valve for refrigeration equipment (hereinafter referred to as "solenoid valve").

This Standard applies to solenoid valve, of which the nominal diameter is not greater than 40 mm, and of which the pipes, high-and-low pressure steam pipes use R22, R134a, R404A, R407C and R410A as the refrigerants. Solenoid valves of using other refrigerants may reference to this Standard for use.
