Tungsten Carbide Balls for Valve Pair for Oil Industry V11-125/150/175/225/250/300/375

The valve ball and seat is a important part of the oil field mining pump, its using directly decides the service life of pump.According to the corrosion characteristics of oil, oil Wells can provide different materialWe can produce the API 11AX ball and seat in materials stainless steel AISI440C, Ceramics(ZrO2) and hard alloy (tungsten carbide and STELLITE), with advantages of high hardness, wear resistance, corrosion resistance.Each of our ball-and-seat combination is vacuum tested to ensure a perfect seal is obtained in all positions of contact.ST valve ball and seatHalf-finished ST ball and seatMaterials:CODEINSTRUCTIONHARDNESSMATERIALSSStainless steelBall: HRC 58-65Seat: HRC 52-569Cr18Mo(AISI440C)6Cr18Mo(AISI440A)STCobalt alloy castingBall: HRC 56-63Seat: HRC 50-56Cobalt, chromium and tungsten alloySTCobalt alloy, powder metallurgyBall: HRC 53-60Seat: HRC 51-57Cobalt, chromium and tungsten alloyTCTungsten carbideBall: HRA 88-89Seat: HRA 88-89.5Tungsten with cobalt adhesiveZrO2Ceramic ZrO2HV 900-1300ZrO2Size Table:TypeFluid, mm2Dw, mmD, mmd mmH, mmV11-10610715.875020.14211.6812.70V11-12515319.050023.31713.9712.70V11-15022723.812529.66717.0212.70V11-17534528.575035.25520.9612.70V11-22556934.925043.68826.9212.70V11-25086942.862551.05433.2712.70V11-375162357.150078.02945.4719,05ApplicationValve balls and seats are used in the manufacture of valves of submersible sucker-rod pumps, a check valve used for oil and gas production. Valve balls and seats are the most critical parts of the pump, because it is subject to the greatest chemical and mechanical stress.Our packingOur inspection center/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
