Clampseal Blowdown Service Valves provide necessary control for continuous or tandem boiler or turbine blowdown and bottom blow-off service.
For continuous service, blowdown valves are available in Âľ inches through 4 inch sizes with butt or socket weld and flanged ends, in ASME/ANSI Class 900 through 4500. Standard materials are Low Alloy SA 182-F22, SA-182-F91 or SA-105. Specials are available upon request.
For tandem service, blowdown valves are available in ¾” through 4” sizes with butt or socket weld and flanged ends, in ASME/ANSI Class 900 through 4500. Standard materials are Carbon Steel A105, Low Alloy F22 or F91.
Clampseal blowdown valves are fully serviceable in-line using standard Conval tools. The valves feature a uniform one-piece gland, which eliminates the potential for stem damage from gland cocking. With leak-proof bonnet, the cartridge-style packing chamber allows rapid access to valve trim for inspection and maintenance.
