Product Description

The KARFAR model GL7040 Pressure Reducing Valve is  a direct acting valve. It is hydraulically operated and diaphragm actuated. It can be mounted horizontally or vertically in pipeline of fire protection system or other clear water system. It functions to control a preset outlet pressure during a range of flow rate. You can adjust the preset outlet pressure by loosen the nut overriding at the top of the valve, clockwise for increase and couter clockwise for reduce. When it meets the required outlet pressure,  remember to fasten the screw so as to avoid outlet pressure change.
