Classification and characteristics of ball valve

  Ball valve is divided into: floating ball valve, ball valve, ball valve, ball valve, three ball valve, stainless steel ball valve, stainless steel ball valve, ball valve, ball valve, three ball valve, pneumatic ball valve, pneumatic ball valve, electric v

Working principle of high pressure ball valve

  High pressure ball valve it has 90 degrees of rotation, the ball, a circular hole or passage through its axis. Ball valve in the pipeline is mainly used to do cut off, distribution and change the direction of the medium flow, it only need to use the rotat

Valve name

  With the rapid development of science and technology, the production process and product structure of the high pressure ball valve was developed in 1950s. In a short span of 40 years, the technology has been developed rapidly. In western countries, indust

High pressure valve product definition:

  With the rapid development of science and technology, the production process and product structure of the high pressure ball valve was developed in 1950s. In a short span of 40 years, the technology has been developed rapidly. In western countries, indust

High pressure ball valve operation and use

  The new parts in the assembly can be cleaned The use of grease lubrication. The grease should be compatible with the metal material, rubber, plastic parts and working medium. Working medium for gas, can be used for example, 221 special grease. On the sur

Advantages of high pressure ball valve

  1 full bore ball valve fluid resistance small, little flow resistance. 2 simple structure, small size, light weight.

Variety, type of valve

  Gate valve also known as gate valve, is a widely used valve. Its closing principle is that the gate sealing surface and valve seat sealing surface is highly polished, smooth and consistent, mutual fit, can stop the flow of the media, and rely on the top m

Advantages and disadvantages

  Advantages and disadvantages Advantages: with the minimum flow resistance (0); (2) because at work will not be stuck (in the absence of lubricant), so it can be reliably used in corrosive medium and low boiling point liquid; (3) in a wide pressure and te

Daily maintenance of ball valve

  Should not allow the assembly of metal debris, fiber, grease (except for the use of) dust and other impurities, foreign bodies, such as pollution, adhesion or stay on the surface of the parts or into the cavity, if there is a micro leakage occurs, and the

Ball valve application

  Because the ball valve is usually made of rubber, nylon and Teflon as the valve seat sealing ring material, so its use temperature is limited by the valve seat sealing ring material. Ball valve's role is to rely on the metal ball in the role of the medium

Valve seal installation

  the installation of the required signal (electric or gas) to carry out the whole test (to prevent the use of the impact of transport vibration), qualified rear can be installed on the line (wiring according to the electric circuit diagram).

Ball valve pressure limit

  Plate showing the maximum operating pressure valve to allow the maximum and minimum operating temperature.

Ball valve product features

  Three, 1 ball valve in the structure of the use of integrated structure, the 4 valve seat sealing type, less flange connection, high reliability, design and achieve a lightweight.

Ball valve classification

  the bypass valve: valve is generally hydrostatic open, it is the first flat pressure bypass valve, which is filled with water on both sides;

Ball valve features

  One; wear resistance; because the valve core is hard sealing alloy steel spray welding, Three piece ball valve Ring is alloy steel welding, so the hard sealing ball in the switch will not produce too much wear. (its hardness is 65-70): Two; good sealin

Ball valve products

  With the rapid development of science and technology, production technology and product structure of continuous improvement, in a short span of 40 years, has been rapid development into a major valve. In the western industrial developed countries, the use
