Description


A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. Valves are the basic components in piping systems. Valve fittings, like pumps in technology, are often discussed as a separate category. The valve may be operated manually or with a hand wheel, handle or pedal, and may also be controlled to vary the pressure, temperature and flow rate of the fluid medium. The valve can perform continuous or repeated operations on these changes, such as safety valves installed in hot water systems or steam boilers. In more complex control systems, automatic control valves are used as required by external inputs (I. e., to adjust the changing set point of the flow through the pipeline). The automatic control valve does not need to be manually operated according to its input and setting, so that the valve can accurately control the various requirements of the fluid medium. Valves can also be divided into cast iron valves, cast steel valves, stainless steel valves, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual phase steel valves, plastic valves, non-standard customized valve materials, etc.

◆ Product overview

HC41X energy-saving muffler check valve is suitable for water supply and drainage pipelines. The valve flap is guided by the central axis at both ends of the inlet and outlet. It is flexible in opening and closing and can be installed horizontally or vertically. The valve flap is spring-loaded. Its quick closing can effectively eliminate water hammer, has good sealing performance and is closed without noise. It has the advantages of small size, light weight, low fluid resistance, fatigue resistance and long life.
