Product Description
SR202 HVAC used AC24V electric Two-way solenoid valve 1/2'' 3/4'' 1''
Product description:
SR202 electric two-way valve consists of SR202 actuator and SR202 brass valve, used in controlling the cold or hot water pipe on or off in air conditioning system, for the purpose of controlling room temperature. valve is driven by hysteresis synchronous motor, returned by spring. When the valve does not work, it’s in normally closed state, when it works, A opening signal is provided by thermostat, to make the electric valve connect AC power and become opening state, cold water or hot water flows into the fan coil, to provide cool air or hot air for room; once the room temperature reaches the setting point of thermostat, the thermostat will shut down the power of electric valve and the spring will return to make the valve closed, thus cutting off the flow of water into the fan coil. As the valve closed or open, room temperature is always maintained at the thermostat setting temperature range.
SR202 series has two forms : two-way normally closed valve and three-way split valve, the sizes of valve threads are DN15, DN20, DN25 three type.
SR202 electric valve’s actuator and valve itself are installed by threaded sleeve, So, the actuator can be installed after the valve is installed.

CERTIFICATION: ISO, TS, API, GOST, CE....etc
We pay much attention in Test process:
(1) Shell Hydrostatic Test
ANSI B 16.34 Section 7.1 | |||||||
Valve Size NPS | Test pressure | Test Time. Sce | |||||
Below DN50 | 1:5 times the 100°F | 15 Sce | |||||
DN65~DN200 | Rating of ANSI Class | 60 Sce | |||||
Up DN250 | Max. Operating Pressure | 180 Sce | |||||
Test pressure should be above 1.5 times than the valve's Max work pressure (100F) |
(2) Seal Hydrostatic Test
The pressure should be more 1.1 times than working pressure by seal hydrastatic test
ANSI B 16.34 Section 7.2 | |||||||
Valve Size NPS | Test pressure | Test Time. Sce | |||||
below DN50 | 1:1 times the 100°F | 15 Sce | |||||
DN65~DN200 | Rating of ANSI Class | 30 Sce | |||||
above DN250 | Max. Operating Pressure | 60 Sce | |||||
Test pressure should be more 1.5 times than the valve's Max work pressure (100F) | 180Sce |
(3) Seal Air Test
Seal air leakage test is based on 80PSIG(6kgf/cm2) inert-gas or the air reach the test pressure, then close the valve. after that check the valve whether it is leakage or not.
