NAFCO | What Is a Brass Ball Valve

NAFCO | What Is a Brass Ball Valve
Time:2018-05-05 From: NAFCO | Brass Valves China Manufacturer
Brass ball valve is valve that opens and closes through the rotating of a ball with a hole inside, the ball is connected and operated by the handle. The flow passes through the valve when the ball hole in line with pipe way, the valve will be closed when the ball rotates 90 degrees.
Brass Ball Valve Structure
The application of brass ball valves
Brass ball valve is generally used for household water pipes or gas pipes using low-pressure small diameter valve, to shut off, distribute and change the direction of medium flow. The V-shaped open ball valve also has a good flow regulation function, widely used in Chemicals, petrochemicals, petroleum, paper, mining, electricity, liquefied gas, food, pharmaceuticals, water supply and drainage, municipal, machinery and equipment, electronics industry, urban construction and other fields.

The features of brass ball valves
The main characteristic of the ball valve is its compact structure, low fluid resistance, and no flow resistance for the full-diameter ball valve. Reliable sealing, simple structure, small size, light weight, easy maintenance, sealing surface and spherical surface are often in closed state, not easy to be eroded by medium, easy to operate and maintain, suitable for general working medium such as water, solvent, acid and natural gas, etc. It is also suitable for use in poor working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. It is widely used in various industries. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes, it will not cause Erosion of the sealing surface of the valve can be applied to a wide range of applications, from small to several millimeters in diameter, up to a few meters in height, and from high vacuum to high pressure. The ball valve body can be integral or modular.
There are two types of ball support: floating ball valve and fixed ball valve.
1. Floating ball valve: Its main feature is that the ball has no supporting shaft ball to support the valve seat at both ends of the valve inlet and outlet. The valve stem and the ball are active links, so this ball valve ball is held in place by the two valve seats and is in a "floating" state.
2. Fixed ball valve: Its feature is that the ball is integrated with the upper and lower valve stems, and the ball can rotate freely along the vertical axis of the valve passage, but it cannot move along the axis of the passage. Therefore, the fixed ball valve has a small torque, a small deformation of the valve seat, a stable sealing performance, and a long service life, and is suitable for high pressure and large diameter applications.

NAFCO | How to Use Radiator Valves Correctly

From: NAFCO-China Radiator Valve and Brass Fittings Manufacturers China In first place, thermal metering users should always pay attention to matters of decoration, d o not change the position of the room thermostatic valves. Tips for installation of radiators and thermostatic valves: 1. Try not to wrap the radiators, because the radiator cooling received restrictions, resulting in a relatively slow increase in room temperature, increasing heat loss. 2. We must promptly repair if the radiator leaks which will increase heat loss. 3. As a result of polygons inside the tube caused by stagnant water circulation, affecting the heating effect, it is set in addition to the exhaust valve on the top floor, each radiator tail in accordance with the manual deflation valve, deflation action to be small, to prevent twist off To the water flow out promptly tighten the deflation valves.
