 Features
Outlet stop valve is actuated using 80psig
pneumatic actuator gives remote on/off operation. Non-isolatable relief valve protects downstream
system and pipe work. Intermediate relief valve not required. Cartridge principle allows full maintenance
of all valves with block welded in situ. Material selection provides good resistance
to humid environment on site. Instrumentation drillings removes requirement
for substantial pipe work
