Q: What does the PN on the valve mean?: 1, mark "ON25" and "PN16" respectively what does that mean? 2, the valve above has an outer six corners, so PN16 refers to the nominal pressure of 16 kg valve. Valves on the fittings are standard parts, special

Q: What is the difference between valve j941H-40 and j41H-40?: I see "valve design manual" category code table, in front of 9 of the electric drive, no 9 is the ordinary hand wheel drive.

Q: What does the valve "4" mean?: An inch of eight points, home tap, valve is generally 4 points

Q: How about leaking water pipe valve?: What specific circumstances, I teach you repair what valve, how big, which seal leaks

Q: Chinese valve and a valve which is better?: These two brands are domestic big brands, as long as the quality is good, good appearance, good after-sales service on the line, as for the brand, it is a personal choice

Q: In the fire drawing, what valve does the following valve represent?: 1, fire drawings, the following valve signal valve and alarm valve.2 、 signal valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve. The output signal is stable and reliable for a long time.3 、 alarm valve products are wet alarm valve, dry alarm valve, rain alarm valve, pre acting alarm valve and so on. It is the core component of wet automatic sprinkler system. The water enters from the bottom of the valve body and closes the check valve through the dead weight inside the valve body to form a standby system with water pressure. The high pressure gauge indicates the system pressure, and the low pressure gauge indicates the pressure outside the system. When the protected area fire, high temperature make the nozzle temperature sensing element of blast nozzle sprinkler system, pressure drop, the valve opens, water flows continuously into the system, the nozzle opening, continuous sprinkler. At the same time, a small amount of water enters the alarm tube from the inner hole of the valve seat, passes through the filter, the retarder, and then pushes the hydraulic alarm to alarm. In addition, after the pressure switch is activated, the electrical signal is issued and the make-up water is started.

Q: Hydrant valve leaks, how do you close other valves? Specific steps?: Crown valve pressFirst, make sure the front of the fire hydrant has a gate valve or butterfly valve Yes, it will be closed and replaced by the lineNo, then useSecond, the pressure of the pipeline to see how big, and if it is rare, replace it with water

Q: Which valves are used in the power station?: Water supply system: butterfly valve, gate valve, eccentric hemisphere valveOil and gas system: stainless steel ball valve, stop valveFire fighting system: gate valve, relief valve, relief valve, sprinkler system

Q: What is the diameter of a general pipe valve?: In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.

Q: Is there any difference between the valve and the water valve?: It doesn't make any difference. The valve can pass through the water or the oil

We have advanced technologies, facilities, resources and talented personnel for processing, developing, studying, designing and manufacturing of different kinds of valves. Our main products are wafer and lug type butterfly valves, slim pinless butterfly valves, flanged valves, gate valves, check valves, ball valves, and Y-strainers in medium and low pressure rate. Our valves are widely applied to water draining, power generation, petroleum, chemical industry, heat supply, metallurgy, medicine, and grocery, as the throttling and shutting-off equipment.
