Additional details on the definitions of pressure difference ∆pv: Maximum admissible pressure difference over the valve at every stroke position, limited by noise level and erosion. With this parameter, the valve is characterised as a flow element with specific hydraulic behaviour. Monitoring the cavitation and erosion along with the associated noise increases the service life and the operational capacity. ∆pmax: Maximum admissible pressure difference over the valve at which the actuator can reliably open and close the valve. The following are considered: Static pressure and flow effects. This value ensures trouble-free stroke movement and closing of the valve. The value ∆pv of the valve is never exceeded. ∆ps: Maximum admissible pressure difference over the valve in the event of a malfunction (e.g. power fail- ure, excessive temperature and pressure, pipe break) at which the actuator can close the valve tightly and, if necessary, maintain the operating pressure against atmospheric pressure. Because this is
