Are the two small ball valves normally installed on the valve body in the open or closed position?

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Generally, the ball valve handle is parallel to the channel of the ball.

Fire stabilizer pump is the stabilizer pump with the main pump, from the pool to the system to maintain the system pressure, the stabilizer pump must be maintained in normal times, maintain the pressure of the pipe network, in the event of a fire, should still be Changzhengyan can run for a period of time, until the main fire pump starts, must be set up according to the main and standby pumps. Due to the need for the stabilizer pump to maintain the running state, it is a waste of energy, and the stabilizer pump is in working condition for a long time. The leak-proof ball valve should always be closed.

When the valve with the downstream self-draining beam function is closed, the line pressure acts on the outer surface of the upstream seat ring, so that the seat ring is close to the ball. If the medium leaks from the upstream seat into the valve cavity, when the pressure in the valve cavity exceeds the downstream line pressure, the downstream valve seat will detach from the sphere and the pressure in the valve cavity will be released downstream of the valve. Therefore, the leak-proof ball valve should always be closed.

Summary. Good afternoon, let you wait for a long time, the fixed ball valve can not only have one side of the seat<> the fixed ball valve generally has two sealing surfaces, so it is usually two seats.

Good afternoon, let you wait for a long time, the fixed ball valve can not be the front cavity only one side of the valve of this balance seat Oh<> fixed ball valve generally has two sealing surfaces, so it is usually two valve seats. Silver shirts.

Is there anything wrong with one seat, the two stems have been supported.

Flat ball valves must have two seats to provide greater leakage resistance and stability. If there is only one seat, the body may leak from the other end. Therefore, it is recommended that the fixed ball valve use two seats, and the manuscript is accompanied by filial piety to achieve better performance and performance.

If there is only one valve seat, when the valve is closed, the sealing surface between the ball and the valve seat will be stuck by the medium pressure, and if it is completely sealed without the method, it may cause air leakage or water leakage. In addition, it is not enough to meet the flow requirements in both directions by the sail side of a single seat, so fixed ball valves usually have a pro-<> with two seats

Summary. Unfortunately, it is not possible to have a fixed ball valve with only one seat.

Unfortunately, it is not possible to have a fixed ball valve with only one seat.

Sticking ball valve is a commonly used valve, which is widely used in various industrial fields due to its simple structure, good sealing and long service life. There is a ball inside the body of the fixed pulse ball valve, which controls the flow of the medium by rotating the ball. Both ends of the sphere need to contain a valve seat to achieve a complete seal.

If there is only one side seat, then the medium will leak from the other side, and effective control and closure will not be possible. Therefore, a fixed ball valve must have two seats in order to function properly.

One side is sealed.

Solid ball valves have a ball inside the body that rotates the ball to control the flow of media. Both ends of the ball need to have valve seats to achieve complete sealing. If there is only one side of the seat, then the medium will leak from the other side, and it will not be possible to effectively control and close it.

One side did a two-way seal.

This is not recommended.

Seats are required at both ends of the ball to achieve a complete seal.
