5. Maintenance is convenient, the ball valve has simple structure, tightly closed circle ordinary activities, remove the transform are convenient. The lack of the Industrial Valves as follows: 1, the fluid resistance is big, open and close the required force is larger. Second, ball valve, ball valve office principle is love rotary valve to the valve is smooth or blocked. 。 In the valve is closed, so be sure to disc increase pressure force, to force the tightly closed surface is not leaking. A, as of valve by valve ownership forced tightly closed valve, open or close the valve stem travel relatively short, and has very good cutting action, get this valve very fit as a medium truncated or adjust and throttling use. 3, tightly closed, tightly closed between friction force is small, the survival of the fixed number of year is longer than the other. Ball valve body can be a group, also can be combined. 6. On the paper or full close, spherical stereo and seat tightly closed surface from the media, media, won't be moved on the surface of the valve tightly closed denudation. 2. Simple structure, big and small, light weight. Two kinds of high pressure ball valve is a floating ball type, 2 it is fixed ball type. When medium by below the disc into the valve, the operation needs to overcome the resistance force, is the stem and packing friction and the initiation of thrust by medium pressure, close the valve strength is stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens. And ball valve in the line more connected than flexible stem confluence, shunt, and medium flow switch, at the same time also can close any Marine valve channel and make the two additional cohesion. Ball valve switch light, big and small, can make it very large diameter, tightly closed reliable, simple structure, convenient maintenance, often in the closed tightly closed surface and the ball surface, not easily be medium erosion, in seventy-two won a wide range of applications. 7. Suitable for wide use, size QiXiaoEr to several millimeters, big to a few meters, from high vacuum to high pressure can be applied. Ball valve is mainly used to cut off or connect pipe in the media, can also be used for the regulation of fluid and the stem, the hard tightly closed v-type ball valve inside the v-shaped ball core of carbide surfacing and have very strong shear force between metal seated, especially suitable for use in the fiber, the fine makings solid medium. 3. Emergency reliable, up to now ball valve tightly closed surface materials widely used molecular compound plastic, tight sealing ability is good, have been widely used in the vacuum system. 2, small office tour, opening and closing time is short. 3, poor regulation performance. 2, uncomfortable to use with larger particles, viscosity, easy to knot the medium of coke. 4. Convenient operation, opening and closing a sudden, from the whole piece of paper to seated just rotate it 90 & amp; 度; For easy distance of the stem. The valve has the following advantages: 1, simple structure, production and maintenance more convenient. Q: the difference of ball valve and the valve and a unique place a: ball valve itself is the main distinctive local structure is compact, tightly closed reliable, simple structure, convenient maintenance, often in the closed tightly closed surface and the ball surface, not easily be medium erosion, easy operation and maintenance, suitable for use in water, solvents, acids and natural gas and other medium of general office, and also suitable for use in conditions of despicable medium, such as oxygen gas, oxygen, hydrogen, methane and ethylene, etc. , in seventy-two won a wide range of applications. By the valve is called the spherical valve, belonging to force tightly closed valve, the valve is closed, it is important to increase on the disc pressure force, to force the tightly closed surface is not leaking. Has the following advantages: 1. Fluid resistance is small, the resistance coefficient and the equivalent length of pipe section. As of valve disc once in an open state, the seat and disc tightly closed between surface no longer contact, and has very good cutting action, close the valve very adapt as medium truncated or adjust and throttling. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.

There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their y gate valve effects. However, recent studies have provided valuable insights into how the intake of may result in improved cast iron valve.
You get a wide variety of security, durability and manageability options across rising stem gate valve. Here’s a link of the brand Mech Valve.
Shenzhen Mech Valve Trading Co., Ltd. always focus on the situation of global market and understands the importance factors of manufacturing flanged gate valve.
