Function
Our TÜV-certified electrohydraulic safety valve control system reliably protects your plant, boilers, pipelines, and downstream systems against overpressure. The control system complies with the applicable safety standard DIN EN ISO 4126-5 and is certified with a component identification mark (Bauteilkennzeichen) as well as SIL3 according to DIN IEC 61508. The safety control system is an interplay between the following components: steam pressure check device, safety valves (safety block) on the hydraulic unit, and a disc spring assembly in the actuator. The process pressure is monitored at the steam pressure check device using a 1-out-of-3 (1oo3) protection system.
You can obtain the steam pressure check device in the design best suited for you: either wall-mounted, fully enclosed, or with a support profile for free-standing installation. This component consists of a combination of 3 impulse lines, shut-off valves, pressure switches, and an interface panel to the hydraulic unit. This ensures the highest possible safety for your plant, your employees, and the environment.
