gate valve

[Delphinus]

PVC gate valves are insanely hard to find in Calgary. Don't know why. Western Pump didn't used to have them, what they had that they called "gate" valves were in fact "knife" valves. Don't know if that's still true nowadays but I'd be surprised. I think Red Coral is about your only bet for a proper gate valve. Before Red Coral came along I always had to mail-order for gate valves. Ocean Aquatics and Bulk Reef Supply and J&L are places that will have them. Maybe mops.ca.
