rotors
BH
The standard BH Series rotor is fabricated open-end style, the most common rotor assembly design.
I
Open rotors refers to the open
pocket at each end of the rotor .
Default design comes with 6 vanes.
Rotor is perfectly designed and manufactured to have a close radial clearance tolerance of 0.10 mm

Shaft sealing
BH
We are using labyrinth seal, which is a mechanical seal that fits around the axle or shaft
to prevent the leakage of any particles.Generally, Labyrinth seal is composed of many
threads or grooves that are tightly fit inside the casing, thus making difficult for the dust
to pass through a long and difficult path.
Labyrinth seals on rotating shafts provide non contact sealing action by controlling the
passage of particles through a variety of chambers by centrifugal motion, as well as by
the formation of controlled material vortices.
‘Double labyrinth Seals’ are filled with flock pads, and greased on each side of the valve.
These are standard with all BH Series valves.
Labyrinth Seal
Grease Purge - Standard Valves is fitted with a grease purge unit over the labyrinth seal.
By creating a grease filled cavity between the seals, it prevents the escape of any dust
particles or gases.
Air Purge - When grease cannot be used, air or other gases can be used to purge the
seal so all dust particles or product gases are flushed back into the product stream.
BH Valve Body
BH
The standard BH Series body is fully cast on a single piece reducing the number of seams for
wear. In addition, as all of the components are manufactured from cast iron, the valve has all of the
advantages of cast iron over traditional mild steel including superior corrosion resistance, better wear
properties and thermal stability.
