Pls confirm below different versions of actuators
Valve Actuator gear
our A20 actuator gear is brass(biggest gear) + stainless steel
Our electronic components are basically imported, all choose the better quality of the accessories, such as switches, we use better quality Taiwan switch.
When you inquiry the valve, pls confirm the detail technical data :
1)valve size2)material, brass or stainless steel?
3)thread BSP or NPT?
4)quantity?
