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
