2 Liquid Control is accomplished by using line pressure or an external pressure source for actuation of the Compact Design and Mechanical Simplicity - Lower maintenance costs. In-Line Serviceability - Reduced maintenance time. Drip-Tight Closure - Positive valve shut-off. No External Packing Gland - Reduced chance of leakage to Application Notes Suitable for horizontal or vertical applications. Maximum ViscosityAll Valves will operate satisfactorily up to 200 SSU (45 mPa s)1 viscosity. For operation on higher viscosity products, consult the factory.

Provides electrically-actuated, two-stage closure when operating in conjunction with positive displacement meters equipped with electro-mechanical preset counters. Meter protection against overspeed is provided by a flow-limiting pilot sensing pressure drop across a valve inlet-mounted orifice with Thermal ReliefThe check features prevents reverse flow should valve outlet pressure exceed inlet pressure.
