V15 valves are designed for use on M-15 and M-25 positive displacement flowmeters; V-30 valves are for use on M30, M40, and M60 positive displacement flowmeters.
V15 & V30 valve operation is smooth and easy regardless of the line pressure since the vector forces are directed at right angles to the valve opening mechanism and are never in opposition to it. 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.
Liquid Controls valves are designed for a wide range of applications and flow rates and have minimum head loss. Careful engineering and construction ensure smooth, accurate, and controlled operation.
