Glossary of TermsPressure Terminology1. Maximum operating pressure differentialThe maximum pressure differential (the difference betweenthe inlet and outlet pressure) which is allowed for operation,with the valve closed or open. When the downstreampressure is 0 MPa, this becomes the maximum operatingpressure.2. Minimum operating pressure differentialThe minimum pressure differential (differential between theinlet pressure and the outlet pressure) required to keep themain valve fully opened.3. Maximum system pressureThe maximum pressure that can be applied inside thepipelines (line pressure).(The pressure differential of the solenoid valve unit must beless than the maximum operating pressure differential.)4. Withstand pressureThe pressure which must be withstood without a drop inperformance after returning to the operating pressure range.(value under the prescribed conditions)Electrical Terminology1. Apparent power (VA)Volt-ampere is the product of voltage (V) and current (A).Power dissipation (W): For AC , W V.A cosθ. For DC, W V.A.(Note) cosθ shows power factor. cosθ 0.62. Surge voltageA high voltage which is momentarily generated in the shut-offunit by shutting off the power.3. Degree of protectionA degree defined in the “JIS C 0920: Waterproof test ofelectric machinery/appliance and the degree of protectionagainst the intrusion of solid foreign objects”.IP65: Dust-tight, Low jetproof type“Low jetproof type” means that no water intrudes inside theequipment that could hinder it from operating normally bymeans of discharging water for 3 minutes in the prescribedmanner. Take appropriate protection measures, since adevice is not usable in an environment where a water drop issplashed.Front matter 9Others1.
