Control and safety valves
Control-valve expertise: Cv/Kv sizing, characteristics, cavitation, flashing, noise, trim, actuators and fail action. Spare parts for older ABB Kent Taylor valves.
Explore valvesFrom control-valve selection and closed-loop positioning to fully pneumatic installed systems. Geyser IC supplies valves across brands and provides detailed support for ABB instrumentation.

Explore valves
PositionMaster EDP300 and TZIDC V18345 as the main families, plus flameproof TZIDC variants and AV pneumatic or electropneumatic models.
Explore positioners
JAA/JAF/JAG and Deltapi N transmitters for pressure, differential pressure, level and flow in fully pneumatic systems.
Explore pneumatic instruments
TEIP11 V18312H and TEIP11-PS V18311H convert 4–20 mA to 0.2–1 bar / 3–15 psi, with field, control-room and Ex versions.
Explore convertersThe final element changes flow and therefore the process variable.
Converts air or energy into linear or rotary valve movement.
Compares setpoint with actual position and adjusts actuator air in a closed loop.
Converts current into pneumatic pressure without actual position feedback.
Measures and controls a variable without electronics, using a standard pneumatic signal.
Generates commands and manages logic, interlocks, PID and supervision.
The valve physically modulates fluid flow; the positioner closes the loop on actual actuator position; the I/P converter only converts an electrical signal into a pneumatic one.
For legacy installations, plants with pneumatic architectures, environments avoiding local electronics or where continuity with existing instrumentation is the priority.
No. Control-valve supply is multibrand. ABB remains an important part of our positioner, pneumatic and I/P portfolio.
Yes. Older ABB/Kent Taylor valves are no longer a current range, but we support spare-parts sourcing, retrofits and multibrand replacement.
