Continuous Blowdown Valves

The continuous blowdown valves are needle valves designed for operation in open position. their function is mainly to control a continuous flow of steam andor water under high ap.
For that reason the design and materials must be such as to minimise the effects of a fluid stream in condition of flashing or made of water containing sometime abrasive particles.
The outlet of our valves is purposely venturi tube-shaped. the bonnetiess design enables easy dismantling, inspection and maintenance. the stem is rising, non-rotating. a local stroke indicator shows the position of the disk.
The materials used for these valves are indicated on page 2 for the most requested material schedules, namely: material schedule 71, with carbon steel body; material schedule 22, with chromemolybdenum alloy steel body.
