Applications
■ Oil and gas industry, chemical and petrochemical
industries, power plants, shipbuilding
■ For gaseous and liquid aggressive media that are highly
viscous or crystallising, also in aggressive environments
■ Test benches and calibration equipment
■ Control panels (e. g. wellheads, actuators), lubrication
systems, dry gas seal systems
■ Sampling systems for process analysis

Special features
■ Increased safety with metal enclosed valve seats and
double valve body seal
■ High-quality machining guarantees smooth operation with Fig. left: Model IBM2, block-and-bleed valve manifold
low torque and low wear Fig. right: Model IBM3, double block-and-bleed valve
■ Leak-tested tightness in accordance with manifold
BS 6755 / ISO 5208 leakage rate A
■ Customisable arrangement with ball and needle valves
■ Customer-specific combination of valves and instruments
