Butterfly valve test and installation troubleshooting methods
Butterfly valve test and adjustment: 1. The butterfly valve is a manual, pneumatic, hydraulic, and electric component that has been strictly debugged before leaving the factory. When rechecking the sealing performance, the user should evenly fix both sides of the inlet and outlet, close the b...Read more -
Performance and working principle of triple eccentric metal hard seal butterfly valve
The working principle of the triple eccentric metal hard seal butterfly valve: For triple eccentric metal sealing butterfly valves, in addition to the two eccentricity of the valve stem and the valve plate, the sealing surface of the valve plate and the valve seat is in the shape of an obliqu...Read more -
The installation and maintenance of globe valves
Globe valve in operation, all kinds of valve parts should be complete and intact. Bolts on the flange and bracket are indispensable. Thread should be intact and no loosening is allowed. Fastening nut on handwheel, if found loose should be tightened in time, so as not to wear the connection or l...Read more -
Globe valve advantages
(1) the structure of the globe valve is simpler than the gate valve, and the manufacture and maintenance are more convenient. (2) the sealing surface is not easy to wear and scratch, good sealing, open and close between the valve disc and the valve body sealing surface without relative sliding, ...Read more -
Comparison of the advantages and disadvantages of electric valves and pneumatic valves, the difference between electric valves and pneumatic valves
Electric valve Electric valve actuators are mainly used in power plants or nuclear power plants, because the high-pressure water system requires a smooth, stable and slow process. The main advantages of electric actuators are high stability and constant thrust that users can apply. The maximum t...Read more -
The characteristics of Forging valves
1. Forging: It is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. 2. One of the two major components of forging. Through forging, the as-cast...Read more -
The characteristics of Casting valves
Casting valves are valves made by casting. Generally, the pressure ratings of cast valves are relatively low (such as PN16, PN25, PN40, but there are also high-pressure ones, which can reach 1500Lb, 2500Lb), and most of their calibers are above DN50. Forged valves are forged and are generally u...Read more -
Correct installation of valve gaskets
To ensure the sealing of the valve piping system, in addition to selecting suitable sealing materials, it is also necessary to install the gasket in the following correct manner: The gasket must be placed in the center of the flange, which is especially important for shoulder flanges; to ensure ...Read more -
The performance and characteristics of the flow-limiting check valve
Installed at the inlet of the water pump, the LH45-16 series flow-limiting check valve is mainly used in a system where multiple pumps are connected in parallel and the number of units is changed for flow adjustment. Play the role of limiting the flow of the pump and stabilizing the head. The d...Read more -

THE SEVEN ELEMENTS OF THE INDUSTRIAL VALVE （2）
4. Hoisting force and hoisting moment: Opening and closing force and opening and closing torque refer to the force or moment that must be applied to open or close the valve. When closing the valve, it is necessary to form a certain seal specific pressure between the opening and clo...Read more -
The seven elements of the Industrial valve （1）
1. Strength performance of the Industrial valve : The strength performance of the valve refers to the ability of the valve to withstand the pressure of the medium. The valve is a mechanical product that bears internal pressure, so it must have sufficient strength and rigidity to ensure long-ter...Read more
