Copyright 218 TI-P45-51 EMM Issue 2 BBV utomatic or Manually ctuated Boiler Blowdown Valves DN15 to DN65 Description The BBV is specifically designed for the removal of suspended / deposited solids water from the bottom of steam boilers. The BBV is available in air / water actuated manual versions. The air / water-actuated version is supplied with a manual h lever. The valve is spring-to-close on power failure the manual version can easily be upgraded to an automatic version. When used with a Spirax Sarco blowdown controller the automatic version provides timed control of blowdown, ensuring that the recommended blowdown occurs with the minimum of heat loss avoids duplication omissions. The valve can be fitted with a mechanical switchbox. This can be linked to the blowdown controller or a BMS system to indicate when the valve has not closed. Principal features: - Easily upgraded from manual to automatic operation. - Dedicated self-adjusting self-cleaning spindle seals. - Engineered for the specific application of bottom blowdown. - Flow pressure assists closing. vailable types of boiler blowdown valve: ir / water pneumatically actuated supplied with a manual actuation lever BBV43 PN / M BBV63 PN / M BBV83 PN / M Steel body Stainless steel body lloy steel body Manually actuated complete with a manual actuation lever BBV43 M BBV63 M BBV83 M Steel body Stainless steel body lloy steel body Please note: ll of the 'M' versions can be automated to ' PN / M'.
