Conval's Clampseal Blowdown Service Valves

press release
Monday, February 04, 2013

Conval, a provider of high-performance valves, offers Clampseal Blowdown Service Valves to provide necessary control for continuous or tandem boiler or turbine blowdown and bottom blow-off service.

 

For continuous service, blowdown valves are available in ¾” through 3" sizes with butt or socket weld ends, in ASME through 4500. Standard material is Low Alloy SA 182-F22 and F91. For tandem service, blowdown valves are available through 3" sizes with butt or socket weld and flanged ends, in ASME Class through 4500. Standard materials are Carbon Steel A105, Low Alloy F22 or F91. For both applications, other materials are available upon request.

 

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 or packing leaks from gland cocking. With pressure assisted bonnet seal, the cartridge-style packing chamber allows rapid access to valve trim for inspection and maintenance. The pressure seal backseat provides maximum valve integrity by ensuring a positive internal guide for the valve and stem and disc assembly. This also securely isolates the packing from line pressure when the valves is fully open, to increase packing life.
