Product Name: Plastic Non Return Cartridge Check Valve for Sprayer Ov10 Model NO.: OV10 Application: Household Usage Standard: ANSI Flow Direction: Reversing Sealing Form: Seals Function: only Allows Water to Flow in One Direction and Pre Pressure: Low Pressure Structure: Tubular Connection Form: Cartridge Material: Plastic Temperature: Low Temperature Media: Water Size: 10mm Seal Material: EPDM Spring: SS304 Trademark: XHnotion Transport Package: Plastic Bag Specification: ROHS, REACH, CE, ACS, FDA Origin: China HS Code: 8481804090 Product Description Cartridge Check ValvesCartridge check valves(also called non-return valves)are designed for simple installation and offer outstanding performance inside mating housing. Theyarevalveswhichonlyallows water to flow in one direction and prevents backflow.XHnotion cartridge check valves are not only for water, also for air now.Applications include faucets, showers, valves and heating systems for residential or commercial installations, as well as pumps,All themodels are 100% tested during production for drip tight operation. Maximum temperature and pressure rating is for most models 200F(90C)/230psi. The average cracking (opening) pressure of most valves is between 0.25and 0.33of a psi.Working PrinciplesIn static conditions (no flow)The check valve is normally closed. The spring tension forces the plunger into itsseat keeping the check valve closed.In dynamic conditions (flow)The water pressure exceeds the spring tension. The plunger is lifted off its seatallowing water to flow through the valve.In backflow conditions (reversed flow)If the pressure downstream of the valve increases (back pressure conditions) or ifthe system pressure upstream of the valve decreases (backsiphonage conditions)causing the flow to reverse direction, the spring-loaded plunger closes andprevents backflow.Features and BenefitsZero leak at low and high pressure and temperature.Generous flow structure promise the lowest headloss.Compact, easy installation, 8mm-50mm diameter to meet all the system.No thread connection to avoid potential leakageDetailsSpecificationsMaterialAcetalhousing,core,cover;EPDMO-Ring;SS304SpringMediumwater,airSize8mmto50mmCrackingPressure0.25PsiMaxPressure230PsiMaxtemperature100C(212F)ProductionCapacity1,000,000pcseachmonthPackingDetailsPolybag,outcartonandpallet.PaymentTermT/T,PAYPAL,WESTERNUNIOnDeliveryTime3-20daysafter/confirm/iingtheorderMiniumOrderQuantity2000pcsCertificateROHS,ACS,FDA,REACHFAQPackingTransparentplasticbag+whitesmallbox+neutralcarton+palletCustompackagingareavailable,XHnotionbrandpackagingareavailableShipping:Exportport:NingboorShanghai,ChinaShippingway:bysea,byair,bycourierDeliverytime3daysto30daysdependsonactualorders.PaymentTermsWeacceptT/T,L/C,Paypal,westernunion,etc.SamplesPolicyForregularfittingsbelow20pcs,freesamplesagainstyourcourieraccountoryoupickupfromus.Forcustomitems,wewilldiscussbyemail.ReturnPolicy:Weassureyou1yearpolicyaftershipment.Ifthereisanyproblemduringthisperiod,pleasecontactusforsupport.
