Hydraulically operated, piston actuated, off-line surge anticipating valve
that immediately opens in response to the pressure drop associate with
abrupt pump stoppage. The pre-opened valve dissipates the returning high
pressure wave; thereby, eliminating the surge. The valve smoothly closes
drip tight as quickly as the relief feature allows; thereby, preventing closing
surge. The valve also relieves excessive system pressure.
Bermad 800 Series valves are hydraulic, pilot operated, piston actuated,
oblique pattern, globe valves with a seat assembly and double chamber
unitized actuator.
The valve’s hydrodynamic body is designed for unobstructed flow path and
provides excellent and highly effective modulation capacity for high
differential pressure applications.
The 800 Series operate under difficult operation conditions with minimal
cavitation and noise. They are made of the highest quality materials suitable
for different mining applications.
