This valve is a design upgrade from Canton Racing’s prior Accusump valve. The machined billet body improves weight and durability while also providing a more appealing look. The design of this valve improves upon the rubber diaphragm design by utilizing a piston design instead.
This valve also decreases it’s installed length due to it’s body over previous models. The valve also offers improved refill timing by slowing the refill rate when the pressure is low.
