Hancock Flow Control Blowdown Valve

Additional Information

Yarway/Hancock 5525/5535 globe valves are built for demanding boiler and steam service. Their quad V-port disc, micrometer indicator, and renewable seat design ensure precise control, tight shutoff, and long service life.

 

  • Pressure Class: Up to ASME Class 800

  • Sizes: ½″ – 2″ NPS

  • Connections: FNPT or Socket Weld

  • Materials: Carbon steel body, stainless/Stellite trim, GRAFOIL® packing

  • Standards: ASME B16.34, Section I Boiler Code

 

Ideal for boiler blowdown and control applications in power, industrial, and HRSG systems. Hardened trim and renewable seats reduce maintenance and downtime, while precision internals improve flow control and sealing performance.
