WIKA IV2 Block and Bleed Valve

About this product

Product Introduction For dual valve manifolds, blocking and venting versions are standard configurations. Globe valves isolate the process from measuring instruments such as pressure gauges, switches, or transmitters. By closing this valve, the instrument can be safely disassembled for calibration or replacement services. The exhaust valve allows for safe exhaust of the instrument before disassembly or zero point inspection. 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. To ensure the performance of the complete system, an additional leak test is carried out on the instrument hook-up. Special Features 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. Applications 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. For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
