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.
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee on
Refrigeration & Air-Conditioning Equipment of Standardization (SAC/TC238).
Responsible drafting organizations of this Standard. Zhejiang Dunan Artificial
Environment Co., Ltd., and Hefei General Machinery Research Institute.
Participating drafting organizations of this Standard. Zhejiang Hongsen Machinery Co.,
Ltd., and Zhejiang Hengsen Industry Group Co., Ltd.
Main drafters of this Standard. Li Weicao, Chen Huafeng, Zhang Mingsheng, Zhou
Shuigen, and He Yongshui.

Solenoid Valve for Refrigeration Equipment
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.

3  Terms and definitions 
Following terms and definitions apply to this document.
3.1
Solenoid valve for refrigeration equipment
The valve that utilizes the electromagnetic force generated by the coil energized excitation
to drive the valve element to open or close.
3.2
Direct action-type solenoid valve
The valve that is opened and closed by utilizing the electromagnetic force generated by
coil energized excitation to directly drive the valve element to realize open-close.
3.3
Pilot-type solenoid valve
The valve that utilizes the electromagnetic force generated by the coil energized excitation
to drive pilot valve; then through the pilot pressure, open and close the main valve by the
pressure differential of upper-lower parts of valve element.
3.4
Normally closed solenoid valve
The valve that is closed when coil is not energized, and opened when coil is energized.
3.5
Normally open solenoid valve
The valve that that is opened when coil is not energized, and closed when coil is
energized.
