Boiler Level Sight Glasses Brass Series VN200 Catalog

Douglass brass level sight glasses allow for a view of the level in a tank. The valves are forged in one piece, ensuring excellent resistance to pressure and adverse conditions. Because this equipment is designed for use in boilers, the standard connection is 1/2″ NPT, and the design pressure for the level valves is up to 200 PSI.

Depending on the working pressure and temperature, the type of level tube will be recommended (standard wall, high-pressure wall, or extra-reinforced wall). Likewise, appropriate seals can be recommended, which can be made of Viton, EPDM, or Teflon.

The equipment can have protective rods, which can be made of stainless steel 304 threaded at the ends, or aluminum pressed at the top.
