Q: How about the valve?: In 1998 began the formal production of valves. As the company expanded in size, in September 2003, changed its name to the British HV VALVES LIMITED (HUDDERSFIELD), referred to as the United kingdom. The design and production of various types of valves, widely used in power, oil, chemical, offshore platforms and other fields, with its excellent quality and service to win the praise of the vast numbers of users.

Q: High and low pressure valve is how to distinguish?: Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.

Q: I would like to ask this valve (not too clear, is it possible to call the valve), what is the specific name of the professional? Where can I buy it?: From the appearance of it is not too good to say, if it is the valve, only one-way valve.The valve usually consists of the stem, spool, seat, body, seal, and so on. This figure feels more like a filter that connects a pressure vessel to an inlet or an inlet.I've seen a lot of filters like this, usually open with -drain filter inside. Play a role in the filter of some large magazines, you can change, more metal, the mother is relatively small (relatively large hole)

Q: What does 3/4''mean in the name of the valve?: Upstairs answer is very clear, 3/4 refers to the caliber of the valve is 3/4 inches, equal to the national standard DN20, (20mm) commonly known as 6 points. The most common family is 1/2, equal to DN15, commonly known as 4 points. Another marked 1.6 refers to the pressure of 1.6Mpa., equal to 16Kg, to bear the pressure.

Q: How to suppress the valve?: Valve pressure is generally divided into 2 parts. One is shell pressure test, one is sealing test pressureShell pressure test is 1.5 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the shell test pressure will reach 24 pressureThe pressure on the seal is 1.1 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the pressure test on the seal will reach 17.6 pressure. That's all right.

Q: Why is copper used in cryogenic valves?: Copper, which is rarely available, is easily deformed at low temperatures and is much more WCB or WCC.Below -46 degrees C, SA352, LCB.LCC

Q: Is the filter also valve?: Filters are generally used in the pipeline, are ancillary products, strictly divided, it does not belong to the valve category

Q: What do O and S mean on the valve?: Generally used in process valves, operating conditions required to open and close, especially in the case of pneumatic actuators installed, the loss of power and gas supply valve when the state

Q: How to carry out the valve strength test and air tightness test?: All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed

Q: What kind of valves are best used for sand drain valves?: Refinement of the Chinese market demand for the valve, like a Pyramid structure. Spire for all imported products, quality, precision, high prices, small amount of monopoly high-end users. The central part of the tower is a wholly foreign-owned and joint venture site, which corresponds to medium and high-end customers who require high quality valves and moderate prices. As for domestic enterprises, they are basically hovering at the bottom of the tower, vying for low-end users in the form of quantity and price. With the increasing rationalization of user purchasing behavior in China, more and more attention has been paid to brand and quality, and the products of sole proprietorship and joint ventures are becoming more and more popular. At the same time, the sole proprietorship and the joint venture enterprises have gradually eroded the market share of the imported products by improving the quality and reducing the cost.
