I'll just chime in as a satisfied buyer - I've been very happy with these valves in my setup. Perfect valve to use for controlling the flow off a pump when you're running a HERMS or RIMS, or for fly sparging.
Unlike ball valves, they can be CIP'd. I tore mine down after the first wash, and they were spotless.
They're a little oversized for regular march pumps, which just means you need a fine touch to dial in low flow rates. But, if your brew system is ever going to grow, these would easily handle the flow rates you'd be seeing even from multi-barrel sized systems.
