- Q:Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is so,Ball valve leakage of this place, how do? Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is the case, how can I ask?
- It may be there when rust, so the Water Leakage, move it off slowly, rust, water Heicha out.
- Q:Open the pressure relief valve core hole with what
- Eccentric semi ball valve you say is a kind of ball valve, ball valve is a relatively new category, it has some advantages of own unique structure is divided into a type eccentric semi ball valve and side mounted eccentric semi ball valve in the maintenance of several, mainly according to the structure to pack type eccentric semi ball valve the structure is with a cover, can be in the pipeline maintenance, convenient and labor-saving, eccentric semi ball valve in the appearance structure 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 the cost, and side mounted valve has the advantages of compact structure, light weight, suitable for valve installation space requirements.
- Q:Ball valve specifications are represented by 2 FF,
- FF refers to the form of connection between the valve and the pipe lineFF, or Flat Face, is a common form of flat flange connection
- Q:How many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Big 50, pleaseHow many points of the ball valve, corresponding to a bit valve? Is there a detailed conversion form? How to convert? What is the basis for the conversion? Is there a formula? Beg you greatly! Don't forget the detailed form!
- No detailed conversion forms are required. How many inches is the representation of inches?.In English, 12 inches are 1 feet, 1 inches =8 cents.So: 1/2 "ball valve, =4 sub ball valve, 1/4" ball valve, =2 sub ball valve, 3/8 ball valve, =3 sub ball valve, and so on.Just a simple conversion relationship.
- Q:What is the difference between ball valve Q41F-16C and Q41F-16P?
- Q41F-16C ball valve material is carbon steel, Q41F-16P material is 304. No difference between the others. I hope you'll be satisfied.
- Q:PPR ball valve diameter is 3 cm, what is the specifications?
- Is it an outer diameter or an internal? Write on the handle of the ball valve. It's DN20, that's the 20 ball valve. It's DN25, that's the 25 ball valve
- Q:Is the drain valve the same as the ball valve?
- Not the same, the drain valve generally refers to the pressure relief valve, when the pipe pressure exceeds the pressure set by the valve, it began to relieve pressure, when the pipe is less than the pressure set by the valve, automatically shut down. Ball valve can only achieve the switch function. Of course, if you take the ball valve as the drain valve, you can also only manually manual operation, and the pressure relief valve is automatic.
- Q:Where to buy the ball valve?
- Use less to the local hardware market, use more direct to find a company to buy
- Q:Role of ball valve DN20-Q11F-16
- Q11F ball valve is to control the circulation and cut-off of the pipeline medium.
- Q:What are the applicable conditions of ball valves?
- As the ball valve is usually made of rubber, nylon and PTFE as the seat ring material, so its use temperature is limited by the seat ring material. Ball valve is the cut-off role of the metal sphere in the role of the media, in the plastic valve seat between each other to complete the compression (float ball valve). Seat ring sealing ring under certain contact pressure, elastic-plastic deformation occurs in some areas.
