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
GL43H flange type Y filter is the use of hydraulic control valves and precision easy to plug the mechanical products necessary for the filter equipment. Usually installed in the inlet end of the hydraulic control valve and other equipment, to prevent particulate impurities into the channel, causing blockage, so that the valve or other equipment failure and can not be used normally. The structure of the Y-type filter is simple, the flow resistance is small, and the dirt can be removed online without dismantling.
◆ Typical installation diagram
1, simple structure, good reliability;
2, easy to disassemble, easy to clean and maintain;
3, filter specifications, to meet the requirements of different occasions;
4. Low price and long service life.
