Smith MeterValves

Model 215 Wafer Sphere3"-12" Digital Control Valve

The Smith MeterModel 215 Digital Control Valveisa high-performance, wafer-sphere valve with a solenoid-

controlled pneumatic/hydraulic actuator.When used in conjunction with one of the Smith MeterElectronic Valve Controllers (e.g., Model SS1, Accu-Load, or MiniLoad), a Model 215 Valve provides precise,trouble-free, low pressure drop, preset loading, and/orflow control of virtually any flowing liquid. The Model215 is particularly well suited for applications on heavyfuel oils or lube oils where viscosity limits the use ofhydraulic valves.

Features

Operation is independent of fluid viscosity andpressureto assure proper control under virtually alloperating conditions.

Wide fluid compatibilitycan be assured by properselection of valve-wetted materials.

Fail-safe operationsince valves are spring-loadedfail-to-close.

Pre-wired, explosion-proof junction boxsuppliedas standard.

Main valve meets NACE MR-01-75 requirements.

Figure 1 Model 215 Valve Schematic

Operation

The valve schematic in Figure 1illustrates the simplicityof the solenoid-controlled actuator system of the Model215 Valve. The normally closed (N.C.) and normallyopen (N.O.) solenoids, located on the pressure andrelief lines (respectively) of the actuator, control theoperation of the valve. Opening the pressure line andclosing the relief line, by energizing both solenoids,allows high pressure air or hydraulic fluid to enter theactuator, pushing the diaphragm and opening the valve.Conversely, de-energizing both solenoids allows thehigh pressure in the actuator to relieve to atmosphereor back to the hydraulic reservoir, permitting the actuatorspring to close the valve. Closing off both the pressureand relief lines (energizing the N.O. solenoid only) locksthe valve in place. The needle valve settings control thevalve opening and closing speeds.
