Valves that ensure reliable, high sealing performance after bypass blow. Periodic maintenance of steam system is followed by blowdown on bypass lines by supplying high pressure steam at start-up. However, globe valves often installed on bypass lines are commonly susceptible to internal leakage as the build-up of dirt and scale and the erosion of valve trim prevent the valve from closing completely. The TLV Bypass Blow Valve BD800 was developed to eliminate these problems.

Application areas:

• High temperature and high pressure applications, such as steam trap bypass lines.
• Bypass or other lines: for blowdown or elimination of steam locking.
