AccessoriesBlock-and-bleed valve2-valve manifoldModels IV20 and IV21WIKA data sheet AC 09.19Applications Shut off and vent pressure measuring instruments For gaseous and liquid aggressive media that arenot highly viscous or crystallising, also in aggressiveenvironments Process industry: Oil & gas, petrochemical, chemicalindustries, power generation, water and wastewaterSpecial features Low-wear design due to non-rotating spindle tip in thebonnet Low torque and smooth operation of valve handle even athigh pressure Enhanced safety due to blow-out proof bonnet design Valve seat tested for leak tightness per BS6755 /ISO 5208 leak rate A Customer-specific combination of valves and instruments(hook-up) on requestFig. left: Model IV20, square versionFig. right: Model IV21, flat versionDescriptionWith 2-valve manifolds, the block-and-bleed version isstandard. The shut-off valve separates the process frommeasuring instruments such as pressure gauges, switchesor transmitters. By closing this valve the instrument canbe safely dismounted for services like recalibration orreplacement. The vent valve allows the safe venting of theinstrument, prior to the dismounting or for zero point check.Through the non-rotating spindle tip, the wear of the sealingelements is reduced. This results, particularly with frequentopening and closing, in a noticeable increase in the servicelife.Through the blow-out proof design of the valve, workingsafety is improved, especially in applications with highpressure loading.As an option, WIKA offers the professional assembly ofvalves and pressure measuring instruments and also otheraccessories into a ready-to-install solution, also known as ahook-up. To ensure the performance of the complete system,an additional leak test is carried out on the hook-up.WIKA data sheet AC 09.19 06/2019Data sheets showing similar products and accessories:Needle valve and multiport valve; models IV10 and IV11; see data sheet AC 09.22Valve manifold for differential pressure measuring instruments, models IV30, IV31, IV50 and IV51; see data sheet AC 09.23Page 1 of 9
