Angle Strainer Filter Valve With Pressure Gauge

      DUNYUN ball valve with strainer and pressure gauge is an integrated valve component that combines three core functions: medium shut-off control, impurity filtration, and pressure monitoring. It is widely used in HVAC underfloor heating systems, water supply and drainage systems, and industrial fluid systems.

      DUNYUN valve integrates a ball valve (for medium shut-off), a Y-type/basket strainer (for impurity interception), and a pressure gauge (for pressure monitoring) into a single valve body, eliminating the need for separate installation of three independent components. It not only significantly saves installation space but also reduces the number of piping joints, lowering the risk of fluid leakage. It is particularly suitable for space-constrained scenarios such as branch circuits of underfloor heating manifolds and small pumping stations.

      The built-in pressure gauge provides a direct visual display of real-time pressure in the pipeline, enabling operation and maintenance personnel to quickly assess the system's operating status:

      When the strainer element is clogged, the pressure difference in the pipeline rises, and the pressure gauge reading increases abnormally, serving as a timely reminder to clean or replace the element.

      When pipeline leakage or insufficient pressure occurs, the pressure gauge reading drops, allowing for quick fault location and preventing system inefficiencies in heating/water supply or equipment damage caused by abnormal pressure.

      The integrated strainer effectively traps solid impurities such as sand, rust, and welding slag in the water, preventing these contaminants from entering downstream precision components including water pumps, flow meters, underfloor heating coils, and solenoid valves. This avoids issues like valve core wear, pipeline blockage, and coil scaling, significantly reducing the maintenance frequency and replacement costs of downstream equipment.

      The DUNYUN ball valve structure features quick open-close operation, allowing full medium shut-off or flow with a 90° rotation of the valve stem. When cleaning the strainer element or maintaining downstream equipment, simply closing this ball valve cuts off the medium supply, eliminating the need for additional shut-off valves. This streamlines the maintenance process and shortens system downtime.
