Opening Time: 200ms up to 1500ms , Closing Time: 500ms up to 2000ms

Max Viscosity: 38 cSt or mm2/s

Features

Maximum Allowable Pressure or Design Pressure: 24 bar (ESV 100 Series), 18 Bar (ESV 101 Series)

Minimum operating differential pressure : 0,35 Bar (For 1/8” up to 1”) and 0,5 Bar (For 11/4” up to 2”), (internal exhaust system (for ESV 101 Series)

Valve has sealing o-rings

Suitable AC and DC voltage, high voltage tolerance

Coil interchangeable without dismantling the valve (don’t matter AC or DC)

High flow rate, high reliability,high mechanical strength

Various flow rate options, wide range of orifice options

Mounting position, optional any position but preferably solenoid coil vertical on top

The fluid passing through the valve must be filtered

Flow rate (Q) can be usually calculated as a function of pressure, density and flow coefficient

According 97/23/EC Pressure Equipment Directive (PED), 2006/95/EEC Low Voltage Directive (LVD) and 2004/108/EC Electromagnetic Compatibility Directive (EMC)
