Q: What valve is the DN 25?: DN25 is just a caliber, a variety of valves, depending on your actual needs to buy Valves, water or gas, or other special functions, are the basis for the purchase of the valve must be provided

Q: G what's the meaning of the valve?: G is the diaphragm valve, valve type code, there are other types of valve code.A D is a safety valve, butterfly valve, check valve (H valve), J is the cut-off valve, throttle valve is L, P is Q is the drain valve, ball valve, S trap, U X is a plunger valve, plug valve, Y valve, Z valve.

Q: The customer sent an inquiry sheet, in which check valve DE50, balance valve DE25, stop valve DE75, and I want to know what de stands for, because the price of plastic and cast iron is different. What does de usually mean in the industry?: Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.

Q: In the decoration, I do not know where to get the valve, what kind of products should be bought?It is hard to fit the valve in the water inlet of the house. If not, can you? Will it have any effect on future use?: There are two types of valves used for decoration:1. inlet pipe valve: general use of ball valve, can adjust the size of water.2. triangle valve for soft tube: used for water tank, basin, bathtub, toilet, water heater hose and water connection.The water valve is best fitted to facilitate overall or partial maintenance.

Q: The general signal valve installation, or other valve installation is not installed with the groove flange clamp hoop Yucca or direct way? What's the convenient way to install the following diagram? I don't understand. Neither groove, flange nor hoop. Thank you, sir!: For clip type, the two flanges on the pipe are drawn with studs, and the middle is the butterfly valve

Q: What does the ZH41 valve ZH41 mean, and what other specifications?: Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel

Q: I would like to ask commonly used water valve what kind of? What are the characteristics?: The valve is usually composed of two parts: the actuating mechanism and the valve bodyAccording to the power used by the executing agency, the valve can be divided into four kinds: manual, pneumatic, electric and hydraulic. According to its function and characteristics, it can be divided into on-off valve, regulating valve, electromagnetic valve, electronic type, intelligent type, etc.According to the type of the body: through single seat, through two seater, angular, diaphragm, three links, eccentric rotation, butterfly, sleeve type, spherical and other 10 kinds of; according to the valve body material: cast iron, cast steel, forged steel, carbon steel, stainless steel, copper, plastic valves.

Q: What does valve 41F-40C mean?: 4: refers to the flange connection;1: on behalf of the structure of the form, different valves have different meanings;F: the sealing material is fluoroplastic;40: nominal pressure is PN40bar;C: the valve body is made of carbon steel, but the valves above PN25 shall be omitted from CAccording to the incomplete model provided, it is estimated that the ball valve is Q41F-40

Q: Tell me the exact address, or the phone number in the market. Where is the industrial zone (the valve) in Hefei? Please help, thank you: On the valve network to find the best, you can find the valve business in Anhui

Q: How can the material be checked by valve approach? What experiments do you need?: May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
