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 size
2)material, stainless steel or PVC ?
3)working voltage DC12-24v?
4)thread BSP or NPT or no thread?
5)quantity?
6)cable length, 0.5m is OK for you?
