Whether the inlet valve of the pump can be used as a clamp on butterfly valve

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, Chaoda, 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.

Yes, the common connection methods are clamps and flanges.

<> commonly used clamp-on butterfly valves, such as D71X-16Q, handle clamp-on butterfly valves as an example:

Its parameters are: <>

Valves with metal seals generally last longer than valves with elastomeric seals, but it is difficult to achieve a complete seal. Metal seals can accommodate higher operating temperatures, while elastomeric seals have the disadvantage of being limited by temperature.

If a butterfly valve is required to be used as a flow control, the main thing is to choose the correct size and type of valve. The structural principle of butterfly valves is particularly suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical industry, water treatment, etc., but also used in the cooling water system of thermal power stations.

There are two commonly used butterfly valves: clamp butterfly valve and flanged butterfly valve. The clamp butterfly valve is to connect the valve between the two pipeline flanges with stud bolts, and the flanged butterfly valve is to have a flange on the valve, and the flanges at both ends of the valve are connected to the pipeline flange with bolts.

1) High temperature butterfly valve. T>450 °C butterfly valve (2) Medium temperature butterfly valve. 120 c<>

1. Classification according to structural form.

1) Center seal butterfly valve.

2) Single eccentric sealed coal valve.

3) Double eccentric sealed butterfly valve.

4) Triple eccentric sealed stomping valve.

2. Classified according to the material of the sealing surface.

1) Soft-sealed butterfly valve.

1) The sealing pair is composed of non-metallic soft materials to non-metallic soft materials.

2) The sealing pair is composed of metal hard material to non-metal soft material.

2) Metal hard seal butterfly valve. The sealing pair is composed of a hard metal material to a hard metal material.

3. Classification according to the sealing form.

1) Forced sealing butterfly valve.

1) Resilient sealed butterfly valve. The specific pressure of the seal is generated by the elasticity of the seat or disc when the valve is closed.

2) External torque seal butterfly valve. The specific pressure of the seal is generated by the torque applied to the valve shaft (2) Pressure seal butterfly valve. The sealing specific pressure is generated by the pressure of the elastic sealing element on the valve seat or valve plate. The sealing specific pressure is automatically generated by the pressure of the medium.

The unique design of three-way eccentricity enables frictionless transmission between sealing surfaces, prolonging the service life of the valve.

An elastic seal is created by torque.

The clever wedge-shaped design allows the valve to have an automatic sealing function that closes tighter and tighter, and there is compensating and zero leakage between the sealing surfaces.

Small size, light weight, light operation, easy to install.

Pneumatic, electric, hydraulic and manual devices can be configured according to user requirements to meet the needs of remote control and program control.

The material of the replacement parts can be applied to various media, and the lining can be protected against corrosion (lining F46, GXPP, PO, etc.).

Continuous structure diversification: butt clamp, flange, butt welding.
