GL2 Series Filter Valve
Standard flow filter control valve.
View Details
The GL4-1 Filter Valve is equipped with meter and timer dual mode for commercial and industrial water treatment applications with higher flow requirements.
● Meter and timer dual mode: In meter mode, the inlet flow meter enables all workstations to be set according to the required water volume;
● Once the backwash water volume, rinse water volume, and operating water volume (in tons) are configured, each workstation will decrement its set value to "0" before switching;
● If deactivated or in the absence of water supply, the decrementing process halts and retains the current value;
● Aesthetic design with valve body components crafted from high-precision materials;
● Excellent strength and high temperature resistance;
● Main valve body integrated with metal inserts for convenient maintenance operations.
The GL4-2 is an economical version using "One dynamic & two static" three layer ceramic valve core technology, ideal for cost-effective commercial applications.
● Same function and principle as GL4-1 in an economical design;
● Operated via a four-button controller for parameter setup;
● No position recognition rotation required during startup;
● Water inlet and outlet positioned on the valve body side for compact size;
● Wear-free valve core with permanent lifespan;
● Highly reliable for long-term use.
