EMU MAINTENANCE VALVE
The VSP valve is used as third source to feed the network that distributes gases; it is used in case of maintenance of both the control board for medical gas central station and the emergency control board for medical gas central station.
The STANDARD model of VSP valve has an UNI or AFNOR or NIST (5359) outlet according to the customer’s requirements; under the central body of the valve we put a valve that allows to scavenge automatically the gas in case there is too much pressure (over-pressure valve).Standard pressure switch high/low pressure is included.
When we connect the VSP valve, we also install a low pressure gauge connected to the alarm of the central station. This gauge gives the possibility to check the value of the pressure inside the system.
