The WIKA Model 910.13 is an adjustable, spring-loaded piston overpressure protector designed to automatically isolate sensitive pressure gauges and transmitters from damaging pressure surges and spikes up to 1,000 bar.

Featuring setting ranges from 0.4 to 600 bar in brass, 316 stainless steel, or Monel constructions, it is widely utilized across the chemical, petrochemical, oil and gas, power generation, and hydraulic industries to safeguard low-range instrumentation, prevent Bourdon tube rupture, and maintain calibration integrity during process overpressure events.
