Features

• Don’t require differential pressure, internal exhaust system (for ESV 101 Series)
• Compact design
• 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)
• Low flow loss, low power loss
• Various flow rate options, wide range of pressure ratings, 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).
