Q:What does 1000WOG mean on a ball screw valve?

A unit of pressure. WOG is the initial letter of water, oil, and steam. It represents the water, oil, and gas pressure passed by 1000 pounds per square inch.Converted to kg: 1000*0.07*9.8/100=68.6KG

Q:Is a plastic ball valve, connecting France is hot melt.

The valve manufacturing process, through strict raw material quality audit, hold the raw materials, and improve the machining tool and processing technology, to ensure the quality of product, market, to win the trust of customers through technology and excellent quality, so that enterprises can use the electric ball in an invincible position.

Q:Allowable leakage on ball valves: what does CLassVI mean?

This is the valve leakage level, level VIThe GB/T4213-92 standard specifies six grades for the valve leakage. The specific requirements are shown in the standard table. The lowest level is level I, without specific requirements; the highest level is grade VI, i.e., the bubble grade.

Q:How can a steel ball in a steel ball valve be put in?

This kind of ball valve usually has an external direction of compression, an arrow. Usually, the ball is filled from the direction of the arrow tail and inserted or tightened into the circlip.

Q:Ball valve use?

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 appropriate switch, shut-off valve used

Q:To help explain the meaning of the ball valve Q11H-16H, combined with the actual, such valves have wood?

Q:PPR ball valve diameter is 3 cm, what is the specifications?

The PPR32 ball valve with the DN25 is a specification. (DN25 is the nominal diameter of the pipe and PPR32 is the outer diameter of the pipe)The PPR25 ball valve with the DN20 is a specification.

Q:I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......

2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.

Q:What are the structural shapes of the eccentric hemisphere valve, what are their respective characteristics?

I. structural form:The eccentric hemisphere valve is divided into two kinds in its appearance and structure:The coat type: mainly for erosion is very serious in the medium, upper structure replaced maintenance loss of the opening and closing member is very convenient, without the whole valve removed from the pipeline, greatly saves the maintenance time and cost.Side mounted: side mounted, compact structure, light quality valve, applicable to the valve installation space requirements.

Q:How to distinguish between cold water valve and hot water ball valve?

Used of hot water, soft, sealed, and used in cold water
