E. M or AEA Brand Transport Package: Plastic+Wooden Case Specification: 1500*1500*2000mm Origin: China HS Code: 848180 Product Description AEAPilot Operated Safety Valve, with non-flowing pilot, is designed to provide the reliable overpressure protection you have come to expect in acost effective package. This valve is well suited for gas, vapor, and many mixed phase services, including dirty and/or wet application. It is designed acc. to API 526,test according to API 527.This valve's type is A46C Pilot Operated Safety Valve.Pilot operated safety valve, newly structured--is mainly applied to such trades as petroleum &natural gas, chemistry, electric, metallurg &burning gas. It is the best super-pressure protecting equipment on pressure equipment, container or pipeline. It is mainly characteized by shifting direct function of spring to indirect function of quite valve. What's more, main valve, applying for sleeve piston &double sealed seat, is characterized by high precision of action, good recycling function fast turning back to seat, ability to high pressure leaking, long working time and security, together with read-justment on line, automatic turning back to seat after leaking again and again, tight closure, operating and maintaining convenience.Standard Compliance:-Design and Manufacture: API 520-Face to Face(end to end): API 526-Test and Inspection: API 527Design Feature:-Pilot Operated Safety Valve;-Full lift safety valve;-Conventional type, Standard safety valve for fluids and gas;-metal to metal seated;- Load Type: Medium Controlled;-Piping between the pilot and main valves is integrated into the cover to prevent damage and freezing-Integrated Backflow Preventer as standard part-Higher capacity than comparable size with extra orifices-20% less installation space than competitors' comparable models-Supplementary Loading System:-Higher operating pressures are possible-Closing pressure difference of up to -3 %; opening process is independent of back pressure-Functional test and valve adjustment possible during operation-Overpressure tolerance at aminimum of 1% with Pop ActionMain property specificationNormal PressurePN150300600900150Body strengthPs(Mpa)3.07.51522.537.5Set pressurePk(Mpa)0.1-21.6-53.2-108-2510-25Seal pressurePm(Mpa)90%PkReseation pressurePh(Mpa)≥90%PkRelieving PressurePp(Mpa)≤1.1PkLift heightH(mm)≥1/4 d0Appropriate temp.≤250ºCAppropriate MediumAir, oil, water, corrosive mediumCode of throat diameterCodeDiameterCodeDiameterD10L20E13M55F16N60G20.5P72H26Q96J33R115K40T148Materials for main partsNO.Name of partAx46Y/F AF46Y/F MaterialKAx46Y/F Material1BodyWCBWCB2Disc2Cr13/PTFE304/PTFE3Guide3043044Spring50CrVA50CrVA5O RingVITONVITON6Bonnet25257Pilot valvePartsEssential:Valves are delivered at aset pressure, therefore when orderingplease confirm set pressure, medium and temperatureWhy Choose us?1.
