The PVST end plate closes off the valve stack section placed between them by placing it at the end.
Furthermore, the end plate is ensuring Load Sense (LS) is relieved to tank pressure when the valve is not
operated.
The PVSI Start Plates features:
•
Integrated LS pressure relief valve to tank
•
Threaded T port
•
Optional integrated thermal orifice
