SERIES 6000 SAFETY VALVES
• O-ring seats available for exceptional leak-free performance, reduced maintenance cost, multiple cycles with tight shutoff and improved seating integrity.
• Heavy duty casting.
• Wide hex on valve nozzle provides clearance for easy installation.
• Seats lapped to optical flatness.
• Dual control rings offer easy adjustability for precise opening with minimum pre-open or simmer and exact blowdown control.
• Pivot between disc and spring corrects misalignment and compensates for spring side thrust.
• Grooved piston type disc reduces sliding area and friction.
• Heavy duty lift lever assembly.
• Each valve tested and inspected for pressure setting and leakage.
GENERAL APPLICATION
These valves are suitable for use on steam boilers and generators, reciprocating or rotary, portable or stationary air/gas compressors, intercoolers and aftercoolers. Also for pressure vessels containing steam, air or non-hazardous gas and on pressure reducing stations.
