shut-offbleedfor water

Shut off and vent pressure measuring instruments For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments Process industry: oil and gas, chemical and petrochemical industries, power generation, water and wastewater Special features of the block-and-bleed valve Low-wear design due to non-rotating spindle tip in the bonnet Low torque and smooth operation of valve handle even at high pressure Enhanced safety due to blow-out proof bonnet design Valve seat tested for leak tightness per ISO 5208 leak rate A Customer-specific combination of valves and instruments (instrument hook-up) on request Description of the block-and-bleed valve With 2-valve manifolds, the block-and-bleed version is standard. The shut-off valve separates the process from measuring instruments such as pressure gauges, switches or transmitters. By closing this valve the instrument can be safely dismounted for services like calibration or replacement. The vent valve allows the safe venting of the instrument, prior to the dismounting or for zero point check. The non-rotating spindle tip of the block-and-bleed valve reduces the wear of the sealing elements. This results, particularly with frequent opening and closing, in a noticeable increase in the service life. Through the blow-out proof design of the block-and-bleed valve, working safety is improved, especially in applications with high pressure loading. On request, WIKA offers the professional assembly of valves and pressure measuring instruments and also other accessories into a ready-to-install instrument hook-up.
