Specifications safety shut-off IPS

Safety shut-off unit type IPS and DPS

Safety shut-off (cut-off) has been developed to take on an important task in pipeline networks measuring and in regulating stations. A safety shut-off unit ensures that when the outlet pressure rises too high, the pipeline is shut after the safety shut-off. This applies to pressures which are too high (IPS) or too low (DPS). Due to its construction this type is very accurate. The safety shut-off is provided with an indicator that displays whether the safety has been addressed or not.
