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 current safety standard DIN EN ISO 4126-5, features a component identification mark, and is SIL3-certified according to DIN IEC 61508. The safety control system is a harmonized combination of 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 using a 1-out-of-3 protection system at the steam pressure test rig.
You will receive 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 a signaling cabinet that acts as an interface to the hydraulic unit. This is how we ensure the highest possible level of safety for your plant, your employees, and the environment.
