Product Details

Full stem convex ear double eccentric butterfly valve detailed product description

1、 Product Overview

Smooth rod convex ear double eccentric butterfly valveIt is a high-performance butterfly valve designed with a combination of protruding ear connection and double eccentric structure. It has the characteristics of easy installation, reliable sealing, and corrosion resistance, and is suitable for pipeline systems of various media such as water, oil, corrosive gases, etc. It can efficiently achieve opening and closing control of media in chemical, petroleum, municipal and other fields.

2、 Core components and materials

Valve body butterfly plateMade of CF8M stainless steel material, withreliableThe corrosion resistance of the valve ensures stable operation in harsh environments such as strong acids and alkalis, ensuring the structural strength and service life of the valve body.
valve stem17-4PH precipitation hardened stainless steel is selected, which combines high strength and corrosion resistance, can withstand the pressure and torque of pipeline media, and avoid problems such as deformation and corrosion of valve stem during long-term use.
sealing elementMade of RPTFE (polytetrafluoroethylene) material, it has corrosion resistance, sealing performance, and high temperature resistance, and can adapt to a temperature range of -200 ℃ to 260 ℃, ensuring the sealing reliability of the valve under various working conditions.

3、 Structural Design and Advantages

Convex ear Connection StructureAdopting a protruding ear installation method, no additional flange space is required, and installation and disassembly are convenient. It can quickly adapt to existing pipeline systems and has obvious advantages in pipeline maintenance and renovation scenarios.
Double eccentric structureCompared to ordinary butterfly valves, the double eccentric design significantly reduces the contact friction between the butterfly plate and the valve seat during the opening and closing process, effectively extending the service life of the sealing pair and improving the sealing performance, achieving zero or trace leakage sealing effect.

4、 Technical parameters

Nominal diameter: 4 inches
Pressure rating: 150LB
Applicable media: various media such as water, oil, corrosive gases, etc
Applicable temperature: -200 ℃ to 260 ℃ (determined by the temperature resistance of the sealing component RPTFE)
Connection method: protruding ear connection

5、 Application scenarios

It can be widely used in corrosive medium pipelines, petroleum transportation pipelines, municipal water supply and drainage systems, and other scenarios in chemical production, especially suitable for medium pressure pipeline systems with high requirements for installation convenience, sealing performance, and corrosion resistance, to achieve precise opening and closing control of medium flow rate.
