G-REV SERIES - SURGE ANTICIPATING CONTROL VALVE

G-REV SERIES - SURGE ANTICIPATING CONTROL VALVE

PRODUCT DESCRIPTION

The surge anticipating control valves are used for amortizing the surges being created in pumping systems that conduct the water to a higher level. Because of the water speed changes at uncontrolled abrupt stopping of the pump, the pressure fluctuation at high value (surge) takes place. If this pressure fluctuation is not evacuated to the atmosphere, it can cause great damages in the network. The surge anticipating control valve is a safety valve that automatically opens itself up in these situations and evacuates the high pressure surge to the atmosphere.

PROPERTIES

The low pressure pilot valve placed on the main valve sustains the main valve at opened up position before the surge is being created in the network.
The high pressure pilot valve placed on the main valve anticipates the growing pressure surge and opens the main valve.
The pressure signal line connected to the low pressure pilot valve is used for sensing sudden pressure changes.
The main valve works with the system pressure entirely hydraulic.
The valve’s maintenance is quite easy and cheap because of its design is globe type.
The valve works safely even vertical and horizontal mountings.
The surge anticipating control valves are mounted TEE type to the network. The valve’s diameter calculation is done with the
formula.


D : Valve Diameter (mm)
Q : System Flowrate (m³/h)
P : System Pressure (meters)

OPERATING MANUAL

Mount the valve according to the arrow placed on the valve that shows the flow direction.
Mounting isolation valves (gate, butterfly or ball etc.) at the entrance direction for shutting-off the water in the line are recommended to ease the maintenance of the valve.
For the valve’s efficient working it is recommended to use an air relief valve before the valve.
Evacuate the water in the valve’s actuator to the atmosphere to prevent freezing in winter.
Connect the pressure signal line of the valve to the main network.
The adjustment of the low pressure pilot valve must be done due to a value close to the static pressure value.
The adjustment of the high pressure pilot valve must be done due to a value close to the network pressure value.
