G-DKV SERIES - FLOW CONTROL VALVES

G-DKV SERIES - FLOW CONTROL VALVES

PRODUCT DESCRIPTION

The flow control valves are used for sustaining flow amount in the network systems. The flow control valve contains an orifice plate and a difference pressure pilot valve which located on the main valve. An orifice diameter is calculated for the desired flowrate value in the network. The orifice plate is mounted at the exit of the main valve. The difference pressure between the entrance and the exit of orifice plate is adjusted from the difference pressure pilot valve located on the main valve. The flowrate in the network would be stabilized with the sustained pressure difference and the calculated orifice diameter.

5. Strainer

PROPERTIES

The difference pressure pilot circuit which placed on the main valve is adjustable. Thus, the flowrate in the network can be changed.
The flow control valve stabilizes the desired flowrate in the network not effecting from the flowrate changes.
The main valve works with the system pressure entirely hydraulic. The main valves entrance pressure must not be under 2 bar (30 psi) pressure for sensitive adjustment of the flowrate in the system.
A desired exit pressure value can be adjusted easily with the pressure reducing pilot valve placed on the valve.
It is possible to remotely control the main valve with mounting solenoid valves at the desired voltage values on the main valve.

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 valves efficient working it is recommended to use an air relief valve before the valve.
Evacuate the water in the valves actuator to the atmosphere to prevent freezing in winter.
The orifice plate must be mounted to the network at the exit direction of the valve.
Check the flow amount in the valve periodically. If the flow amount is not at the desired values, check the difference pressure pilot valve.
Check the system pressure. The system pressure must not be reduced to 2 bar pressure for a sensitive flowrate adjustment.
Clean the filter (strainer) as shown with 5 according to water pollution degree.
