Thank you for your inputs. A small solenoid valve with a low current consumption like this would be optimal: https://xhnotion.en.made-in-china.com/product/HeXxObDArjas/China-Latching-Solenoid-Valve.html

  This valve would be quite optimal, because it has outer thread ports: http://www.bonavalve.com/showprod.php?prodid=699&backid=0&page=2 I would only need 3/4 inch threads instead of the 1/2 inch threads. Can you find such a valve. I want DIRECT links to the manufacturers like the one above. The solenoid voltage can be up to 6V, but up to 5V would actually be better.

  After thorough evaluation, i found out many of this companies only have an inquiry box and do not stipulate the exact price. I have a list of 8 manufacturers/suppliers/wholesalers, please check my latest entry for the list. I hope it pleases you. Thanks

  But from my research, XHNOTION is one of the most visible suppliers from China for this product
