14 Valves Liquid Controls valves are designed for a wide range of applications, flow rates, and minimum head loss. Careful engineering and construction ensure smooth, accurate, and controlled operation. LC valves offer the important advantages of time-tested reliability and leak-tight shutoff.

Accessories valves V- and VS-Series piston valves for refined petroleum products and industrial liquids The V-Series mechanically actuated piston valves are available in 2" through 4" sizes and are designed for mounting on the meter outlet to provide tight shutoff with smooth and easy operation regardless of system line pressure. Valves may be manually operated or connected via a mechanical linkage to a preset counter on the meter for single stage closure, or two-stage closure to eliminate hydraulic shock. Valves are indexable in 90° increments for up, down, or side facing outlet. E-7 solenoid operated control valve with flow switch for refined petroleum products The E-7 Series solenoid-operated control valves are installed at the meter outlet and are designed especially for use with Liquid Controls LectroCount3, LCR, and LCR-II electronic registers. These solenoid operated piston valves can be applied for either single or twostage closure. The flow control switch switches the pump between low bypass and high bypass mode. Valves provide compact installation and are indexable in 90° increments for up, down, or side facing outlet.
