Choosing a Check Valve

A Check Valve is a type of valve that prevents backflow in a piping system. They differ from gate and globe valves because they do not use handwheels to operate and instead rely on pressure or gravity to control the flow. One of the most common types of Check Valves is the swing valve.When choosing a check valve, the selection process should start with a thorough analysis of the requirements of the application. There are many factors that must be considered, including the line size, pressure gra...

What Is a Check Valve?

The Check Valve is a self-operating valve used in a wide variety of applications. Its purpose is to permit flow in one direction and prevent reverse flow. There are a number of factors that will affect the type of check valve you choose. These factors include cost, initial familiarity, required maintenance, and process media. One of the most common problems with check valves is water hammer. This is a result of water pressure rising too quickly. It can also be caused by improper installation or ...

What Is a Check Valve?

A Check Valve is a mechanical device that limits or prevents the flow of fluids or gases through a pipe. They are generally self-operated valves that allow one direction of flow and prevent the opposite flow. Different types of check valves are suitable for different applications. Some features to consider when choosing a Check Valve include cost, ease of use, maintenance requirements, piping orientation, and process media.Check valves are a common component of plumbing systems. These valves ens...

Valve construction and installation points

1) The installation position, height, and direction of import and export must meet the design requirements, and the connection should be firm and tight.2) For all kinds of manual valves installed on the thermal insulation pipeline, the handle shall not be downward.3) Visual inspection must be carried out before the valve is installed, and the nameplate of the valve should comply with the current national standard "General Valve Mark" GB 12220. For valves with a working pressure greater than 1.0 ...

Ball valve installation precautions

(1) The disassembly and decomposition operation must be carried out only after it is confirmed that the upper and downstream pipelines of the ball valve have been depressurized.(2) Non-metal parts should be removed from the cleaning agent immediately after cleaning, and should not be soaked for a long time.(3) The bolts on the flange must be tightened symmetrically, gradually and evenly during assembly.(4) The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts ...

Disadvantages of ball valve

①Because the most important valve seat sealing ring material of the ball valve is PTFE, it is inert to almost all chemical substances, and has a small friction coefficient, stable performance, not easy to age, wide temperature range and excellent sealing performance comprehensive characteristics. But the physical properties of PTFE, including high coefficient of expansion, susceptibility to cold flow, and poor thermal conductivity, require that seat seal designs must be built around these proper...

Ball valve advantages

Advantages: ① has the lowest flow resistance (actually 0); ② can be reliably used in corrosive media and low-boiling liquids because it will not get stuck during operation (when there is no lubricant); ③ in larger Within the range of pressure and temperature, it can be completely sealed; ④ It can realize rapid opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so as to ensure that it can be used in the automation system of the test bench. When the valve i...

Daily maintenance of ball valve

Having a long service life and maintenance-free period will depend on several factors: normal operating conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion dataWhen the ball valve is closed, there is still pressurized fluid inside the valve bodyBefore Servicing: Depressurize the line and keep the valve in the open position; disconnect power or air supply; disengage the actuator from the yokeThe dismantling and dismantling operations must be carried out after...

Application of ball valve

Since the ball valve usually uses rubber, nylon and polytetrafluoroethylene as the material of the seat seal, its operating temperature is limited by the material of the seat seal. The cut-off function of the ball valve is accomplished by pressing the metal ball against the plastic valve seat under the action of the medium (floating ball valve). Under the action of a certain contact pressure, the valve seat sealing ring undergoes elastic-plastic deformation in local areas. This deformation can c...
