Floating Ball Cast Steel Ball Valve And Fixed Ball Cast Steel Ball Valve

According to the structure of the sealing mechanism, cast steel ball valve is divided into floating ball cast steel ball valve and fixed ball cast steel ball valve. The former mainly through the medium pressure on the end of the ball valve seat, its use of pressure and diameter are subject to certain restrictions. While the latter valve is supported by the upper and lower bearings mounted on the valve body, the position of the ball is fixed and the sealing effect is achieved by pressing the spring and the medium pressure seat against the sphere. So the opening and closing torque is small, suitable for high pressure and large caliber occasions.

What Are The Main Advantages of Cast Steel Ball Valves?

Cast steel ball valve make the hole with a circular hole as the opening and closing parts, the ball rotates with the stem to achieve the opening and closing action of the valve. So, what are the main advantages of cast steel ball valves?

1.the fluid resistance is small, fully open the ball channel, the area of valve body channel is equal to the connection pipe cross-sectional, and form a straight line, the medium flows through the cast steel ball valve, which is equivalent to flowing through a straight pipe, the fluid resistance is minimal.

2.open and close quickly, open and close are convenient and rapid.

3.the structure is relatively simple, smaller size, lighter weight. In particular, its height is much smaller than the gate valve and the shut-off valve.

4.sealing performance is good. Cast steel ball valve is generally used with flexible soft seal.

The Working Principle of Stainless Steel Check Valve

The main function of the stainless steel check valve is to prevent the media from flowing backwards. The check valve is an automatic valve that relies on medium pressure to open and close. With a small valve closure, water hammer pressure is small, long life, reliable performance and other advantages.

Stainless steel check valve automatically open, close rely on the flow of the media,  used to prevent the media back valve. Stainless steel check valve is an automatic valve, its main role is to prevent the media back to prevent the pump and drive motor reversal, and container media discharge.

Detailed Description of Floating Ball Valve

Floating ball valve is one kind of valve consisting of crank arms and float components, can be used to automatically control the water tower or pool surface. It has some advantages, such as simple maintenance, flexible and durable, high liquid level control accuracy, water level from the water interference and opening and closing close water leakage.

Floating ball valve is suitable for chemical, oil, natural gas, metallurgy, and other industries, can be used as pipeline for hydrogen sulfide medium, impurities and more serious corrosion natural gas.

Check Valve Classification

Check valve is the valve that rely on the power of the fluid itself to open and close automatically, its role is to prevent the media back flow. According to the structure can be divided into two categories. In the valve model with "H".

One is the lift check valve: The flap moves along the vertical centerline of the valve body. There are two types of this lift check valves: one is horizontal, installed in the horizontal pipe, the valve body shape is similar to the valve,  the other is vertical, installed in the vertical pipe.

The other is a swivel check valve: The valve flap rotates around the pin, this type of valve has a single, double and multi-flap, but the principle is the same.

We are the leading manufacturer of valves in China, we can produce a variety of check valves, including cast iron check valve, DIN Lift check valve and DIN swing check valve.
