Clark Reliance Series 600 and 700 Valves

• Exclusively Chain Wheel Operated Models
• Seven Models of Series 600 and Series 700 valves offer choices in vessel and gage connections, equalizer tube availability and maximum steam pressure services.
• Refer to the Model Selection Guide for individual model features to meet your specific installation requirements.
• All chain wheel operated models are of outside screw and yoke design.

• Forged steel body to ASTM A 105 Specification.
• Type 303 stainless steel stem.
• On Series 700 models only, one-piece 420F stainless steel replaceable seat (Figure 24) is secured by identical two-bolt packing yokes.
• Single-pitch stem thread allows easy valve operation by chain wheel.
• Stem bushing is positioned outside body, away from high temperatures and corrosive fluids.
• Lower valves provide 3/8" pipe connection and female socket weld connection for blowdown.

Note: Female socket weld connectors are not included when valves are to be welded to water columns.  To specify for the above applications add "C" to model numbers.  Example: Model SG777 (with socket weld connectors) becomes Model SG777C (without socket weld connectors).
