3" and 4" Steel Valves For MS-, MSAA- and MSA Series Meters.
Positive Displacement Meter - VS-Series Valves
VS-Series preset valves are designed to function with a mechanical preset to effectively shut down the flow after a predetermined amount of product is delivered. The preset allows this valve to be mechanically shut down in a single stage or in two-stages. Single stage shut downs are generally utilized with slower flow rates or with more viscous products where hydraulic shock is less of an issue. A two-stage shutdown allows for a slowing of the flow rate before the final positive shutdown, thus avoiding hydraulic shock.
