Product Details

Smooth stem flange double eccentric butterfly valveDetailed product description

1、 Product Overview

Smooth stem flange double eccentric butterfly valveIt is a high-performance butterfly valve designed with a double eccentric structure, combined with a smooth rod and flange connection form, which has excellent sealing performance, mechanical performance, and installation convenience. It is widely used in various medium pipeline systems such as water, oil, gas, etc. in the fields of chemical, petroleum, municipal, energy, etc., to achieve efficient opening and closing control of the medium.

2、 Core components and materials

  • Valve body butterfly plateMade of CF3M stainless steel material, it has reliable corrosion resistance and can work stably in harsh media environments such as strong acids and alkalis, ensuring the structural strength and service life of the valve body.

  • valve stemF51 duplex stainless steel is selected, which combines high strength and corrosion resistance, and can withstand the pressure and torque of pipeline media, avoiding problems such as deformation and corrosion of the 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

  • 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.

  • Connection between light rod and flangeThe light rod design simplifies the valve stem structure and facilitates maintenance and operation; The flange connection method conforms to the general pipeline installation standards, with easy installation and disassembly, and can quickly adapt to existing pipeline systems.

4、 Technical parameters

  • Nominal diameter: 8 inches

  • Pressure rating: 150LB

  • Applicable media: various media such as water, oil, gas, etc

  • Applicable temperature: -200 ℃ to 260 ℃ (determined by the temperature resistance of the sealing component RPTFE)

  • Connection method: flange connection

5、 Application scenarios

It can be widely used in corrosive medium pipelines, petroleum transportation pipelines, municipal water supply and drainage systems, gas transportation pipelines in the energy field, and other scenarios in chemical production. It is particularly suitable for medium pressure pipeline systems with high requirements for sealing performance and corrosion resistance, achieving precise opening and closing control of medium flow rate.
