What is the magnetic lockable brass ball valve?   The magnetic lockable brass ball valve, a type of brass ball valve that with magnetic device and key, has a function to prevent valve operation without permission, especially suitable for public places.     What is the structure of magnetic lockable brass ball valve?   The magnetic lockable brass ball valve included three parts: brass ball valve body, magnetic lock and valve key, as shown below:     How magnetic lockable brass ball valve works?    Brass ball valve is the main part to control the flow open or close, the magnetic lock is used to keep the valve stem from using, the valve keep is to take the magnetic lock off and on, also to switch the ball valve.   The brass ball valve at closing position, magnetic lock installed     The brass ball valve at open position, the magnetic lock removed     The valve key: one end is magnetic key for lock, the other is stem key for brass ball valve

What Is Electric Brass Valve Time:2019-04-28 From: NAFCO | Brass Valves Manufacturers China In the pipeline engineering, the correct selection of electric brass valves is one of the guarantee conditions to meet the requirements of use. If the electric brass valve used is not properly selected, it will not only affect the use, but also bring about bad consequences or serious damage. Therefore, the electric brass valve should be correctly selected in the pipeline engineering design. Working environment of electric brass valve In addition to paying attention to the pipeline parameters, electric brass valves should pay special attention to the environmental conditions of their work, because the electric device in the electric brass valve is an electromechanical device, and its working condition is greatly affected by its working environment. Under normal circumstances, electric brass valves are used in the following working environments:     1. Indoor installation or prot

Important ! Cautions to Install Brass Valves Time:2019-03-29 From: NAFCO | Brass Valves Manufacturers China   The quality of the brass valve installation directly affects the use, so careful attention must be paid.   1. Direction and location   Many brass valves are directional, such as globe valves, throttle valves, pressure reducing valves, check valves, etc. If installed in reverse, it will affect the effect and life (such as throttle), or not at all. (such as pressure reducing valves), even causing danger (such as check valves). Generally brass valves have a directional mark on the valve body; if not, they should be correctly identified according to the working principle of the brass valve. The valve chamber of the stop valve is asymmetrical to the left and right, and the fluid should be passed from bottom to top through the valve port, so that the fluid resistance is small (determined by the shape), the labor is turned on (because the medium pressure is upward),
