Selection of hydraulic control valve design points

Hydraulic control valve design selection points: 1 engineering application of the hydraulic control valve is tested through the manufacturer, all kinds of labels complete, technical information to meet the requirements of the product. 2. According to the functional requirements, choose the type of valve, and then according to the pipeline transportation medium, temperature, building standards and the main requirements, etc., to determine the valve body and sealing parts of the material. Common body materials are cast iron, copper and iron, copper, plastic and so on. Common sealing surface and lining materials are copper alloy, plastic, steel, hard alloy, rubber and so on. Valve body material should be matched with the pipe material. 3. Nominal pressure of the valve 0.6,1.0,1.6,2.5 and 4.0MPa and other different levels, pipeline transport medium, the working pressure should be less than the nominal valve pressure value. 4. The project hydraulic control valve should be set up enough space for management, operation, installation and maintenance, and should comply with the requirements of the pipeline on the valve. 5. Pipe flange connection, the flange should be used to connect the hydraulic control valve; pipe connection using the groove, the groove should be used to connect the hydraulic control valve. 6. Hydraulic control valve should be set in the medium one-way flow of the pipeline. 7. The direction of the arrow on the main valve of the hydraulic control valve must be consistent with that of the piping system. 8. Then the hydraulic control valve pipe should not be blocked, gas resistance phenomenon. In the highest position of the pipe and other gas storage section should be set automatically exhaust valve 9. When the valve is installed horizontally, the valve cover, stem should be up. Vertical installation, the valve cover, stem should be outward.

Non Woven Sanding Belt

Surface conditioning non woven Sanding Belt
This product is made of high quality nylon nonwoven material and great aluminum oxide. It is applicable to handheld and automatic grinding apparatus,with elasticity and small grind,can be good to improve the grinding workpiece ,and easy to replace.

Compared with the traditional abrasives products,nylon abrasive belts have the following advantages: can control the minimum amount of grinding mil,.grinding depth anti-blocking,the minimum of tolerance probability,new abrasives grain continuously exposed in the grinding process,and good effect.

The non-woven, open web, durable construction is designed to resist loading and greatly increase the life of the Belt. Standard Abrasive Non-Woven Discs and Belts offer repeatable finishes for a wide variety of applications.

Application:
Providing additional strength and durability for removing paints,rust, corrosion, exit burrs, weld splatter, parting lines and deburring on ferrous and nonferrous metals.
Blending weld seams and deburring edges
