Thank you for interest in our valves,Firstly,I will let you know China TOFINE advantage valves as below:
More detaisl please visit our website: www.flow-controls.com, Email: sales@flow-controls.com,

So far the Timer control motorized ball valve in Brass could be 1/4",3/8",1/2",3/4",1" and 1-1/4",and Stainless is available in 1/2",3/4" and 1".

* For Stainless steel valve body ,if no special demand,we will provide stainless steel 304, Meanwhile, Stainless steel 316 needs minimum order quantity (MOQ) 60 PCS.
* Actuator housing color can be availabe in Blank,blue and grey.

Then,I will show you what the labels and part number will be :

First,China TOFINE mini motorized ball valves use different actuators,one is A20,the other is A100,their main difference is listed below:

A20 actuator is smaller than A100,see below picture for example:
A20 actuator price is much lower than A100,
For the voltage 5V,12V,24V,A20 can be with manual override and visual indicator,A100 can not be with manual override but can be with visual indicator,

Brass available sizes: 1/4",3/8",1/2",3/4",1",1-1/4"   Using A20 actuator
Stainless steel available sizes: 1/4",3/8",1/2",3/4",1" Using A20 actuator, and 1-1/4",1-1/2",2"  Using A100 actuator

Model: TOFINE-THA20T,  2-way Motorized ball valve from 1/4" to 2"
Serial No.A20:   from 1/4" to 1"
Serial No. A100: from 1-1/4" to 2"

Model: TOFINE-THA20T, 3-way Motorized ball valves in Brass from 1/2" to 1"
Serial No.A20

Model: TOFINE-THA100T  3-way Motorized ball valves in Stainless from 1/2" to 1"
Serial No.A100

Model: TOFINE-TCM30P  2-way Motorized ball valves with Timer control, 1/2" to 1-1/4"
Serial No, A20  



Let's take below specs for example.

A20-T15-S2-B   
A20: Serial No.,  T15: Size-DN15(1/2"),  S2: 2-way Stainless steel,  B: With manual override,with visual indicator

A20-T20-B2-C
A20: Serial No.,  T20: Size-DC20(3/4"),  B2: 2-way Brass,  C: no manual override,with visual indicator

A20-T25-S2-A
A20: Serial No.,  T25: Size-DN25 (1"),   S2: 2-way Stainless, A: no manual override,no visual indicator

A100-T20-S3-C
A100: Serial No.,  T20: Size-DN20(3/4"), S3: 3-way Stainless, C: no manual override, with visual indicator

For example:
if you need to buy the 2-way motorized ball valves in 1/2",Stainless steel,with manual override and with visual indicator,the part number will be: A20-T15-S2-B(" S" means Stainless steel,"B" means With manual override and with visual indicator)

If you need to buy the 2-way motorized ball valves in 3/4",Brass,Without manual override and with visual indicator,the part number will be: A20-T20-B2-C ("B" means Brass, "C" means No manual override and with visual indicator)

If you need to buy the 2-way motorized ball valves in 1" Stainless steel,without manual override and without visual visual indicator,the part number will be :A20-T25-S2-A ("S" means Stainless steel, "A" means No manual override and no visual indicator)

If you need to buy the 3-way motorized ball valves in 1/2" Stainless steel,without manual override and with visual indicator,the part number will be: A100-T15-S3-C  (for 3-way valve the serious code will be A100)

If you need to buy the 2-way motorized ball valve in 1-1/2" Stainless steel,without manual override and with visual indicator,the part number will be: A100-T40-S2-C (for bigger size 1-1/4" to 2" the serious code will be A100)

Besides 2-way or 3-way,Size,Material,Manual override options,the lable also shows the Wiring,Voltage and the Batch number,batch numbers guarantee valves to be tracked in case any problems,

2-way in 1/4" to 1" please refer to A20 Wiring diagram,1-1/4" to 2" please refer to A100 wiring diagram.
3-way in 1/2" to 1",if  Brass valve please refer to A20 wiring diagram,if Stainless steel valve please refer to A100 wiring diagram.
