The SLRV-PO over pressure safety valve is a spring loaded overpressure valve with an integrated pneumatic actuator and it can be activated by remote-control. Thus this safety valve permits to manage its opening during the CIP cycles.
During normal homogenizer operations the pneumatic overpressure relief valve works as a standard spring loaded relief valve: it is closed and it opens when product side pressure is higher than calibration pressure.
Possible working conditions are:
In order to clean internal surfaces of the safety valve, during CIP it is possible to open the valve by supplying air to the pneumatic actuator. All parts connections in contact with the product have gaskets to avoid metal-to-metal surfaces contact and consequently to increase safety valve cleanability.
The pneumatic safety valve has been designed with same process connection used in standard safety valve, therefore it can be installed as retrofit without any machine modification.
