Product Name:    Brass 1/2'' Motorized Valve, 2 Way Electric Shut-off Valve, 1.0Mpa, On/Off 5sec, 2/3/5 Wires.TF20-B2-A.

Technical Parameters:

Question 1: How to identify the model of TF Automated Valve?

For Example:  TF25-B2 -C. 

TF=Our Company Name; 

25=Valve Size, DN15=1/2'', DN20=3/4'', DN25=1'' etc.

B =Brass; S =Stainless Steel; 

2 =2 way valve; (3=3 way valve);

C= On/off valve woth position indicator (we have A/B/C series valve for selection)

Question 2: What is TF motorized valve's advantage compare to other valves?

1) Float sealing struction,No Leak,can be suitable for various water treatment,even high-fouling area.
2) Integrated design of valve body and electic actuator,small size and light weight,very suitable for small equipment.
3) Can replace the solenoid valve in the conditions that the solenoid valve can not be worked.
4) Valve bore full port design, do not lose any flow.
5) Long serving life,approx 100,000 open/close times
6) High reliable working performance & price ratio,you have NOT worries at afterservice and reselling.
7) Low current ≤80MA  (500 mA shown on the lable means the minimum current of external power), suitable for battery driving.
8) Open/close time approx 3~5 seconds,fast response&action.

9) Actuators are sealed to IP67 specifications to prevent water ingress,ideal for indoor or outdoor installation.

Question 3: How do I order valves from TF?

The following factors is important when you ask for the valve price from us:

1. Your Pipe Size = Our Valve Size

2. Your Wokr Voltage:  DC Power: DC5V, DC12V, DC24V?  AC Power: AC12V, AC24V or AC110V-230V

3. Valve Material: Brass Valve or Stainless Steel Valve ?

4. Control Metod: After the voltage confirmed, we can guide you to find suitable control method from our wiring diagrams. Usually, the wires option should be same as your controller or equipment design.

Question 4: How about the quality control of TF brand motorized ball valve?

1, Actuator housing use high quality engineering plastic for prevent aging and UV;

2, Metal gear system can guarantee the valve operation steady and long life working;

3, 200 times electronic performance testing before sending out, each valve should open/closed 200 times by power in this testing;

4, Type ID number to each batch valves;

5, The protection class is also IP67, all actuators are fully sealed to IP67 specifications to prevent water ingress;

6, Floating seal structure, no leak, suitable for heavy dirt or long time working. No leaking, high protection class, NEMA 6 equivalent;

7, Most of other supplier offer reduce port only. TF series motorized valve features a full port ball valve, the valve do not lose any water flow or pressure on the working.

8, Offer NPT thread valve for America and Canada market, and offer BSP thread valve for other country.

9, Different wiring control methods for option which include 2/3/5 wires control, normal open/closed, signal feedback etc.

10. Acquired CE certification and ISO certification.

Most of our old clients used TF brand motorized valve for water applications as bellow:

1. Automated Leak Detection & Water Shut-off System

2. Water heater&boiler system

3. Centre heating system

4. Water treatment, water reclying, water purification

5. Electric Brewing system

6. Smart water meters, solar water systems.

7. Drinking water equipment, washing machine

8. Chemical process, water softener

9. HVAC, central air conditioning, fan coil

10. Water saving irrigation, automatic control system, industrial mini automatic control equipment.
