Whether isolating a pressure gauge during maintenance or protecting a transmitter from pulsation damage, WIKA solutions help ensure consistent performance and safer operation.
Q & A
Valves & Protective Devices Q & A
WIKA valves and protective devices are engineered to securely isolate pressure and process instruments — such as gauges, transmitters, or switches — from the process media during calibration, maintenance, or commissioning. Protective devices (like syphons or snubbers) also help extend instrument service life and expand usability across demanding applications.
Valves act as shut-off mechanisms that separate instruments from fluid or gas processes, preventing leaks or accidental pressurization when instruments are serviced. This isolation protects technicians and equipment alike.
WIKA’s valve range includes stopcocks, shut-off valves, valve manifolds, monoflanges, needle valves, multiport valves, block-and-bleed valves, monoblocks, and ball valves, each suited for specific process and isolation tasks.
Block-and-bleed valves are ideal when you need a simple, compact solution for both blocking (isolating) and bleeding (venting) pressure instruments without complex systems of multiple valves — offering reduced weight and fewer leak paths.
Valve manifolds connect differential or pressure transmitters and gauges to the process, balancing pressure sides (in 3-valve manifolds) or adding venting ports (in 5-valve manifolds), which helps ensure stable readings and easier maintenance.
