SERIES 1200R11 is an electrically operated – hydraulically actuated control valve. The model
1200R11 Surge anticipating valve is a normally closed valve that is manually adjusted
to open in response to the pressure drop thatis related to the sudden stoppage of a pump. When the valve opens it dissipates the returning
high pressure wave thereby eliminating pressure surges that might cause damage to
the pipeline and be hazardous to operators.Once upstream pressure falls below the set
point the valve closes slowly again to a drip tight position.
