Product Information：
This Ball Brass Valve is a brass ball valve owned by IFAN. Both ends are internally threaded. The valve body is all yellow with a hexagonal cap. The handle is a long red handle with the logo of IFAN Valve printed on the handle. Although this Ball Brass Valve is an all yellow brass ball valve, it can also be made all white.
Ball Brass Valve is evolved from a plug valve. Its opening and closing part is a sphere, and the sphere is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing. Ball Brass Valve is mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with V-shaped opening also has a good flow adjustment function.
The Ball Brass Valve is model number 81063 and has a brass core, brass stem, iron nut, iron handle and Dacromet plated.

Product Features:
The following will introduce the common faults and maintenance methods of Ball Brass Valve. The opening and closing of the copper valve is blocked, inflexible or cannot be opened and closed normally, or even cannot be opened and closed continuously, mainly due to the jamming of the valve stem and other parts, mainly the jamming between the valve stem and the packing. Generally, the packing gland is deflected and then touches the valve stem. The treatment method is to install it correctly; the packing is not installed correctly or is pressed too tightly. The treatment method is to pre-tighten the packing and loosen the packing properly; the valve stem and the packing gland are bitten The treatment method is replacement or repair; the treatment method for biting or biting between parts is to properly lubricate the valve stem; the valve sealing surface is scratched, the light column part of the valve stem is bitten and the threaded part of the valve stem is bitten, etc. After the sealing surface is ground, there are abrasive particles embedded in the sealing surface, which are not cleaned up, causing the sealing surface to be scratched. cause abrasions. The treatment method is to use abrasives reasonably, and the sealing surface must be cleaned after grinding. The dirt or welding slag in the medium has not been cleaned up, causing scratches. The treatment method is to clean it again; the valve stem is rubbed with the packing press sleeve and the packing pad, and the medium containing boron will crystallize and form a hard material after leakage. Particles, on the contact surface of the packing and the valve stem, the surface of the valve stem is damaged when switching, the treatment method is to install it correctly, adjust the fitting clearance of the parts and improve the surface hardness of the valve stem; the trapezoidal thread has contamination and dirt, and the lubrication condition is poor; the valve stem The treatment method for the deformation of related parts is to remove the dirt, apply lubricant to the high-temperature copper valve in time, and correct the deformed parts.
