Q: What is a lift rod valve?: The valve stem and valve plate are relatively fixed, and the valve stem rises up when the valve plate is raised

Q: What does the "PN" mark on the valve mean?: The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)

Q: What valve is the DN 25?: This is only the aperture of the valve. It does not represent the form of the valve.

Q: What is the main function of the valve?: Valve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.

Q: How can you replace the other valve when the main valve is not closed and no water is stopped?: Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy.

Q: What should be checked before using the valve?: 5, check valve disc or spool movement is flexible and accurate, no bias, displacement or skew phenomenon6, spring-loaded safety valve should be sealed, positioning lever type safety valve should have the weight of the device7, rubber lining, lining enamel and plastic lined valve body surface should be smooth, the lining layer and the substrate firmly, no crack, blister defects, using high frequency electric spark generator to inspect the lining surface, not found in liner breakdown (white flash phenomenon) is qualified8, the valve flange sealing surface should meet the requirements, and shall not have radial scratches
