Water System

The diaphragm float control valve is hydraulically driven to maintain a relatively stable level of water in the tank. When the water level rises and exceeds the maximum limit water level, the float guide valve is completely closed. When the water level drops to the lowest limit water level, the float guide valve is fully opened and the valve is automatically opened for replenishment. Built-in filter to prevent blockage of the conduit system.

The adjustable pressure reducing valve maintains the output pressure within a preset range through a precise pressure regulator. When the output pressure exceeds the setting range of the pressure reducing valve, the main valve body and the pressure regulator will automatically close and form tightly. Seal.

The slow-closed muffler check valve has a diaphragm type control valve that opens and adjusts the closing speed. Through hydraulic control, when the inlet pressure rises above the valve opening pressure, the valve opens slowly to avoid the impact. When reverse pressure is generated, the liquid enters the valve chamber and the valve closes slowly to form a tight seal. The opening and closing speed can be adjusted by the opening of the needle valve.

The pressure relief / holding / back pressure valve maintains pressure in the upstream line. It is a diaphragm valve that is hydraulically controlled and controlled by a pressure regulator that senses the pressure at the input of the valve through a Pilot regulator to control the opening and closing of the valve. When the input pressure exceeds the set value, the valve opens quickly to maintain the pressure in the line. After the pressure is released, the valve is slowly closed to prevent the impact.

The Y-shaped structure design makes the valve have excellent hydrodynamic performance, the medium resistance is small, and the Cv value is larger than the ball type control valve. Double chamber diaphragm control gives the valve excellent control performance. It can make the valve move smoothly, eliminate the impact and avoid the damage caused by the water hammer. The optional V-type plug is more suitable for low flow and high pressure differentials, which can reduce pipe vibration. The 500 series main valve body can be combined with different guide sub-valves to form hydraulic function valves for various purposes. The valve body and diaphragm are available in various materials and are suitable for various media environments. This product is mainly used in municipal water supply, irrigation facilities, industrial plants, air conditioning and fire water.

The valve body is double sealed by metal and elastic material, and adopts axisymmetric design, so that the water flow breaking area in the valve cavity is always annular, shrinking to the shaft at the exit, avoiding throttling, eliminating cavitation and vibration on the pipe network. And damage to the pipeline. Ideally designed, the fluid is well guided inside the streamlined valve body. Even in the case of high pressure difference, the valve can effectively eliminate the high pressure difference, reduce the high pressure to low pressure, and will not cause vibration and cavitation. The continuous decreasing of the annular flow passage area from the inlet to the contraction section results in a gradual increase in the flow rate without cavitation and no energy conversion of cavitation damage. Whether the piston is in any position, the contraction section is circular, ensuring perfect linear adjustment.
