Product Name: Cw617n Wog Standard Pn16 Electric Actuator Brass Ball Valve Application: Industrial Usage Standard: GB Temperature: Normal Temperature Function: Flow Type: Floating Ball Valve Structure: Floating Ball Valve Channel: Straight Through Type Nominal Pressure: PN1.0-32.0MPa Driving Mode: Electric Connection Form: Thread Material: Brass Media: Wog Ball: Iron Trademark: TKFM Transport Package: Box Specification: 170g Origin: China Product Description SR202 electric two-way valveconsists of SR202 actuator and SR202 brass valve, used incontrolling the cold or hot water pipe on or off in air conditioning system, for the purpose of controlling room temperature. valve is driven byhysteresis synchronous motor, returned by spring. When the valve does not work, it's in normally closed state, when it works, A opening signal is provided by thermostat, to make the electric valve connect AC power and become opening state, cold water or hot water flows into the fan coil, to provide cool air or hot air for room; once the room temperature reaches the setting point of thermostat, the thermostat will shut down the power of electric valve and the spring will return to make the valve closed, thus cutting off the flow of water into the fan coil. As the valve closed or open, room temperature is alwaysmaintained at the thermostat setting temperature range.SR202 series has two forms :two-way normally closed valve and three-way split valve, the sizes of valve threads areDN15, DN20, DN25three type.SR202 electric valve'sactuator and valve itself are installed by threaded sleeve, So, the actuator can be installed after the valve is installed.MaterialDescription:Bodymaterial:ForgedBrassStemmaterial:stainlesssteel(304)Actuatorbase:die-castaluminumActuatorcover:highstrengthfireretardantengineeringplastics(ABS)Sealingmaterials: EPDNTechnical Parameters:Valve size: DN15, DN20, DN25Connection: threaded connectionValve structure: two-way, three-wayMedia: hot / cold waterPressure: PN16Close differential pressure: 0.18 ~ 0.22MpaPower supply voltage: AC220V ± 10%, 50 / 60HZconsumable power: <6.5WRun mode: On or OffValve action time: Opening time: ≤18S Closing Time: ≤7SModelandsizemodelSize(mm)ABDN15two-wayvalve55123DN15three-wayvalve55128DN20two-wayvalve66124DN20three-wayvalve66137DN25two-wayvalve90129DN25three-wayvalve90145SpecificationModelFlowCoefficient(KV)ThreadDifferentialpressureMediumMediumTempAmbientTempPNpowerDN15two-wayvalve1.0(1.5)1/2''0.25Water/Hotwater2-94ºC0-60ºC1.6AC24VAC110VAC220V50/60HzDN15three-wayvalve1.0(1.5)1/2''0.25DN20two-wayvalve2.5(3.5)3/4''0.12DN20three-wayvalve2.5(3.5)3/4''0.12DN25two-wayvalve4.0(4.8)1''0.08DN25three-wayvalve4.0(4.8)1''0.08
