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, brass or stainless steel ?
3)working voltage DC9-24v?
4)thread BSP or NPT?
6)cable length, 0.5m is OK for you?
7)signal control 4-20mA? 0-5v?  0-10v?
