The Controlpres is a new version of the Mascontrol, which has all of the same features as the original with the addition of a built-in pressure-reducing valve, allowing for downstream pressure adjustments according to system requirements. The Controlpres provides for an adjustable downstream pressure between 36 psi and 100 psi. It features all-stainless steel construction. It has a built-in check valve and run-dry sensor and can be used on virtually all pumps. Controlpres, Card No. 35
