I never knew I needed such precise pressure control until I got my hands (or rather, feet) on this aluminum alloy pedal valve. The G1/4 threading ensures a secure connection and the non-slip design is a nice touch for added safety. It's a shame it doesn't come with installation instructions, but once you figure it out it's a breeze to operate. In no time, I was switching between flows with ease. Overall, a great addition to any industrial setup.
