Offshore / Oil / Gas / Chemical / Water / Wastewater / Marine

Notes

The specifications can be designed and satisfied for customers’ special requirements. The product is designed by adopting L.Lai’s high technologies. We have obtained certificates of SGS ISO 9001:2008.

Q:Difference between fireproof and antistatic ball valve and ordinary ball valve: Fire valve is generally aimed at soft sealing material valve, that is, after the fire on the valve, the ball valve can rely on medium force and metal valve seat (body) contact, to achieve sealing, so that the fire does not go down the pipeline. Anti-static valve is for soft sealing material of the valve, when the ball switch and soft seal friction, will produce static electricity, if the pipe is taking the flammable and explosive medium is very dangerous, so the valve will set a device outside the sphere will Unicom electrostatic oriented, to prevent static electricity.Generally like the market valve, a little better quality, they are the default valve is fire, anti-static, the production costs of these two types of valves is bad, at most two or three dollars, which is still much.

Q:What does one inch of an ice ball refer to?: Ball valve inch refers to the nominal diameter of the valve is 1 inches, that is, DN25 valves, mostly threaded connections.

Q:The working principle of the track type ball valve: No wear and tear of switch:The ball core deviates from the valve seat and then rotates, eliminates the friction of the valve seat, and solves the abrasion problem of the seat of the traditional ball valve, gate valve and plug valve.Anti friction valve hard and dense cover:The surface of the ball core is welded with a hard polished sealing surface, which can ensure the sealing performance under very severe working conditions.

Q:Pneumatic two stage ball valve principle: Two section type pneumatic ball valve, pneumatic piston two stage shut-off valve to achieve a two step or two step off the action of the cut-off valve is a special pneumatic valve, provides 0 degrees, 45 degrees, 90 degrees or 0 degrees, 90 degrees, three operating mode 180 degrees.

Q:Domestic water pipe ball valve or cut-off valve?: Ball valve: rotate 90 degrees to switch, but the performance of the valve relative to the cut-off valve.

Q:What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?: Pneumatic angle seat valve is the use of reciprocating actuators, usually in use to withstand fluid work pressure at 1.6MPa. Pneumatic ball valve is to use rotary actuator, to bear high fluid pressure. In normal use, the reciprocating actuator is characterized by its service life over the length of the rotary actuator. Two: easy maintenance. Three: the price is cheap. Personal recommendations in fluid pressure below 1.6MPa, or pneumatic angle seat valve is better?. High pressure, less opening frequency, pneumatic ball valve is appropriate.

Q:The valve nominal 1/2, 3/4 is how much?: Nominal diameter 1/2 3/4 corresponding to DN15 DN20

Q:Who knows why the ball valve is divided into a piece of ball valve, two pieces of ball valve, three pieces of ball: There is, of course, a difference,This is according to the structure of the valve body,The difference between them is whether they are easy to disassemble, for example, the three piece of ball valve is easiest to disassemble.

Q:What's the meaning of the double ball valve in the double ball valve?: By means of "union", the "live" means that the two ends of the valve are connected by a live joint

Q:Is the drain valve the same as the ball valve?: Ball valve in the pipeline is mainly used to do cutting, distribution and change the direction of media flow, it only need to rotate 90 degrees of operation and a small rotating torque can be closed tight. Ball valve is the most suitable switch, shut-off valve used, V ball valve. Electric valve should pay attention to the pipe parameters, but should pay special attention to its use of environmental conditions, because the electric valve in the electric device is a mechanical and electrical equipment, the use of its state by its use of environmental impact. Under normal conditions, electric ball valves, butterfly valves in the following environmental use should pay special attention to.
