Space Applications

Outlet stop valve is actuated using 80psi 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. Material selection provides good resistance to humid environment on site. Instrumentation drillings removes requirement for substantial pipe work
