For home use, you have three types to choose from: CWX, A100, and A20.
What Do They Look Like?
The most obvious differences between these are torque force.
CWX max torque force is 1.7 NM(That's why it can only operate small valves)
A100 max torque force is 10 NM
A20 max torque force is 2 NM.
The open/close time has differences as well. The time of CWX and A20 is the same, 3-5S approximately. The A100 open/close time is about 13-15S.
Because of actuators" different torsion, the applicable valve body is different.
A20 actuators offer more torque than CWX. Fit 2-way brass valve (1 1/4" or less), 2-way stainless steel valve (1" or less), and 3-way brass Valve (1/2", 3/4", and 1").
A100 actuators offer more torque than A20. Well fit bigger valves like 2-way stainless steel valve (1 1/4", 1 1/2", and 2") and 3-way stainless steel L-port valve.(What is T Port and L Port for 3 Way Valve?)
CWX may be used in 1/2" 2-way and 3-way T-port valve. If you need a
3/4" and 1" 2-way valve, we will use a valve body with reduced bore size (3/4"=15mm bore size, 1"=20mm bore size)(What's Reduced Bore and Full Bore?). So, if you want a full bore size valve, we highly recommend you select the A20 actuator.
Manual Switch and Indicator
Manual Switch Only for Voltage Under 36V
CWX:No for Both
A20: Yes for Both
Can I replace the valve body myself?
Why not? As Long As socket fit and torsion is enough.
A lot of customers question description in manual
"Limit Switches Inside, Cut Off Power Automatically When F.O or F.C"
I tested myself and below is my research result. I believe A20 consume 10-25% more power than CWX.
What else do you have?
Water Leak Protection
My application need more powerful and industrial Grade Actuator
We have a Series Called "TCN/R SMART", Using industrial interface, die-cast aluminum housing (N) or ABS / PC + PET Housing(R). Torque UP to 2000NM. The volume is 1/10 of Traditional industrial grade valve.
