The SRV6 is a direct acting sanitary stainless steel pressure regulator designed to reduce pressure in clean and pure steam, liquid and gas systems. Available in 1″, 1-1/2″ and 2″ sizes, the SRV6 is manufactured in 316/316L stainless steel, with all wetted parts mechanically polished to 20 microinches Ra, then electropolished. The angle pattern of the sanitary pressure regulator design ensures that the valve is self draining, while Tri-Clamp® compatible connections ease removal and ensure cleanliness. Diaphragm restraints and valve travel stop, which are standard features, prevents excessive diaphragm movement under vacuum conditions, which extends service life and reduces maintenance costs.

Downstream pressure is set by compressing the control spring. On start-up, flow passes through the main valve resulting in a downstream pressure buildup. As the downstream pressure begins to rise it acts on the underside of the diaphragm, opposing the spring force and causing the main valve to move closer to its seat. This movement throttles the flow, ensuring that the downstream pressure is accurately controlled at the desired set point.
