High Performance Floating Balance Valve - PQ side mounted two way sealed eccentric hemisphere valve – Like Valve Detail:

Product use

Suitable for sewage treatment, pulp, alumina, urban heating, petrochemical, gas, slurry, coal ash.

Product features

1. Large circulation area and small flow resistance. This is because the opening valve core is located in the ball chamber, and the fluid passes through

2. Small operating torque, turn 90 degrees to open and close, easy to operate

3. Tight seal; double eccentric metal hard seal. The structure does not affect the opening and closing, which is the most significant feature of the hemisphere valve

4. Long service life, wear-resistant sealing pair, with compensation, valve seat can be adjusted or replaced
