Bronze Ball Valves
IVR bronze ball valves for industrial service are used for flow isolation in hydronic and thermal networks, water distribution, auxiliary process lines, compressed air, low- or medium-pressure gas systems, and selected Class 1 fluids according to PED 2014/68/EU. The range includes full-bore and 2-way configurations, typically with CW617N brass/bronze alloy bodies and PTFE seats, suitable for applications requiring low pressure drop, fast manual shut-off, and controlled seat leakage.
IVR 45, IVR 46, IVR 47, and IVR 52 are applied in heating, cooling, compressed air, and general industrial fluid circuits, with selection mainly depending on end-connection configuration. IVR 100/A/LD is intended for gas distribution and hydrocarbon service, with PN 20 pressure rating. IVR 230 is supplied with BSP female/female threaded ends and an ISO 5211 mounting pad for actuator installation where automated isolation is required. IVR 954 and its variants are used in hydraulic, thermal, and auxiliary industrial systems with ISO 228-1 threaded connections.
Valve selection should be based on nominal pressure class, thread standard such as BSP, ISO 228-1 or ISO 331, media compatibility with brass/bronze alloys and PTFE, operating temperature, and expected operating frequency. For gas or hydrocarbon installations, the suitability of the exact valve version must be verified against project and regulatory requirements. Maintenance planning should consider access to the lever or actuator, isolation of network sections, and leakage inspection at threaded joints, stem packing, and valve seats after operating cycles.
