Is the diameter of the inlet and outlet flanges the same for the reduced diameter ball valve?

Hello, the same, according to the process requirements on the pipeline, if the pipeline is 300 caliber, the process requirements say 250 (flow), then do necking, save a lot of costs. If the valve is made of 300 caliber, the cost of reaching 250 by opening or other means is not the same, hopefully!

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.

The valve diameter is the inner diameter of the valve.

The caliber is the channel of the valve, and the general one marked with dn or dn50 is the diameter is 50, such as 2, the caliber is also 50.

The unit of nominal diameter of the national standard valve is mm, and the unit of the nominal diameter of the American standard valve is in (inches).

Below 100, 1 inch is equal to.

dn15——1/2”

dn20——3/4”

dn25——1”

dn32——1 1/4”

dn40——1 1/2”

dn50——2”

dn65——2 1/2”

dn80——3”

More than 100: 1 inch is equal to 25mm: such as ND200 - 8".

Generally, it cannot be simply converted, and the correct statement should be corresponding.

Single reducer ball valves are suitable for pipe connections of the same diameter, while double bore ball valves are suitable for pipe connections of different diameters. The single and double diameter reduction of ball valves refer to two different forms of ball valves when they are connected in pipes.

Here are the differences between them:

1.Single bore ball valve: In a single bore ball valve, the inlet and outlet dimensions of the ball early hood valve are the same as the size of the pipe.

This means that the ball valve has the same inner diameter of the flow channel as the inner diameter of the pipe, without any downsizing. Single-bore ball valves are typically used for the same diameter pipe connections and can provide greater land mess and lower pressure loss.

2.Double Reduced Bore Ball Valve: In a double reduced bore ball valve, the inlet size of the ball valve is larger than the outlet size, forming a reduced bore design.

Double reducer ball valves are commonly used for pipe connections of different diameters, which can connect large diameter pipes with small diameter pipes. With the open-bore design, the double-bore ball valve can achieve pipe diameter transitions and control the flow and pressure of the flowing medium.

Reduced diameter insulation ball valve, also known as reduced diameter insulation ball valve, is to meet the special working conditions of customers on the basis of the integrated insulation ball valve to develop a new type of key touch insulation valve, Biliangfan valve has the characteristics of thermal insulation and cold insulation.

1. It is widely used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to convey high-viscosity media that will solidify at room temperature.

2. Due to the use of steam jacket insulation, even if the outside temperature drops below zero, the valve is still flexible to ensure that the oil pipeline can be disconnected, and its advantages are not found in the general control valve of regret hail. It is an ideal control valve for heavy oil pipelines.

3. According to the needs of users, the jacket is injected with steam, heat transfer oil, cooling water, air conditioner, etc. Use the entire valve to cool down or cool down to the desired temperature. It can prevent the medium from crystallizing.

The inner diameter of the valve is smaller than the nominal pipe diameter, indicating that it is like this sign ">

Large at both ends and small in the middle.

Refer to the corresponding flange national standard.

The valve diameter is the inner diameter of the valve.

The caliber is the channel of the valve, and the general one marked with dn or dn50 is the diameter is 50, such as 2, the caliber is also 50.

The unit of nominal diameter of the national standard valve is mm, and the unit of the nominal diameter of the spring filial piety of the Meiliang Fengbiao valve is in (inches).

The conversion is as follows: below 100, 1 inch is equal to.

dn15——1/2”

dn20——3/4”

dn25——1”

dn32——1 1/4”

dn40——1 1/2”

dn50——2”

dn65——2 1/2”

dn80——3”

More than 100: 1 inch is equal to 25mm: such as ND200 - 8".

It can't be simply converted, and the correct way to say it should be corresponding.
