Description
Flange pneumatic butterfly valve
The Flange pneumatic butterfly valve operates as a resilient seated double-flange design which supports international compatibility standards. The valve design accommodates worldwide flange requirements because it matches ASME Class 125/150 and BS 10 Tables D and E and BS 4504 NP 10/16 and DIN ND 10/16 and AS 2129 and JIS10 standards. The valves follow ISO 5752-Table 2 (EN558 Table 13) standards for face-to-face dimensions and ISO 5211 actuator mounting flange requirements. The single valve design enables its use across multiple international markets. The valve body exists in six material options which include Cast Iron and Ductile Iron and Aluminum Stainless Steel and CF8 and CF8M and CF3M. The valve disc options consist of Stainless Steel CF3M,CF3,CF8M Nylon Coated Ductile Iron, Aluminum Bronze and Double Stainless Steel materials.
The stem materials available for this product include 416 Stainless Steel and 304 Stainless Steel and 316 grade stainless steel. The valve seats are available in NBR EPDM PTFE VITON Polyurethane materials. The product operates between -30 °C and + 135 °C (depending on pressure, medium & material) and spans from 2″ to 40″ (25mm to 1000mm) in size. The product serves multiple applications including Potable Water Wastewater Seawater HVAC Sanitary & Chemical uses because it offers high Cv and low pressure drop with a single-piece disc/stem construction. The Pneumatic Actuator which accompanies this product delivers output torque from 10Nm to 8000 Nm while offering control options and pneumatic accessories including Solenoid valve and Limit switch box and Filter and E/P positioner and Hand wheel.

FAQs
What is flange butterfly valve？
The flange butterfly valve functions as a specific type of butterfly valve which controls the passage of liquids and gases. The valve contains a circular disc and stem which operate through an actuator system. The disc contains an opening which enables flow control through the pipe system with reduced pressure loss. The flange connection provides simpler installation and maintenance and repair operations compared to other valve types.
What is a butterfly valve used for?

The disc turns around its central axis which runs perpendicular toThe butterfly valve contains two essential parts which include a central hinged disc and its operating mechanism that operates butterfly valve functions as a specific valve design which controls the passage of liquids and gases through its system.
fluid flow to enable passage of fluid when the valve is open. The valve operates effectively for both low-pressure systems and high-pressure systems that experience significant pressure differences.
What is double flange butterfly valve?
The double flange butterfly valve operates as a mechanical quarter-turn device which controls fluid flow in pipelines through stoppage and regulation functions. The valve consists of two semicircular plates which connect to a spindle that operates with an actuator. The two plates function as check valves because one plate remains stationary while the other plate rotates around it.
The double flange butterfly valve serves multiple industrial sectors which include chemical operations and power plants and oil and gas facilities and iron and steel manufacturing and food processing facilities. The compact design and lightweight construction of these valves makes them an economical choice for managing liquid and gas flow direction and pressure compared to other valve options.
