ASCO Valves

What model numbers of ASCO valves have folks had luck with. For almost $300, there seems like there has to be a cheaper option than the 8210g37.

Thanks.

How about something closer to $40? I’m in email discussions with a company in China right now.

Here’s what they are quoting:
2 port Motorized ball valve CWX-15Q
1/2" full port NPT stainless 2 wires CR04 (normally closed when power off) AC/DC 9-24V,
Female on both ends
