**Product Description:**
The KARFAR GL98001 Multifunctional Filter Piston Type Adjustable Pressure Reducing Valve is a hydraulically operated valve that automatically adjusts the downstream pressure to a preset value by controlling the movement of the main disc. When the downstream pressure exceeds the set point, the valve closes automatically, ensuring stable output pressure regardless of fluctuations in the inlet pressure or flow rate. This model allows for an adjustable pressure reduction range of 10% to 80% of the inlet pressure.
One of the key advantages of this product is its built-in strainer, which saves both cost and space compared to using a separate strainer device along with a standard hydraulic control valve. This makes it ideal for applications where space is limited or efficiency is crucial.
The GL98001 is widely used in daily water supply systems, fire protection systems, and industrial water supply systems. It is designed for durability, reliability, and ease of maintenance.
