Introduction Features Of Metal hard seal flange Motorized Butterfly Valve :
The Motorized Metal hard seal flanged butterfly valve featuring a triple-offset metal hard-seal design, this solution achieves zero-friction sealing with a temperature and pressure resistance of up to 425°C. The valve exceeds 60,000 open-close cycles, making it suitable for demanding applications in metallurgical, power generation, and petrochemical industries. Available in DN50-800 sizes with multiple control options, it represents a reliable choice for industrial fluid control systems.
Standard Features Of Metal hard seal Electric Flange Butterfly Valve :
● The valve body sealing surface is overlaid with hard alloy, exhibiting excellent wear resistance and extended service life.
● The bidirectional sealing function is independent of media flow direction and exhibits an exceptionally low leakage rate.
● Tri-eccentric multi-layered metal hard seal configuration,achieving frictionless contact on sealing surfaces
● The fully open flow resistance coefficient is ≤0.1, approximating pipeline flow resistance, making it suitable for flow regulation applications.
● Metal hard seal: Suitable for high-temperature and high-pressure operating conditions, such as steam and oil/gas pipelines.
● The system offers manual, automatic, or remote control options based on operational requirements, with 4-20mA signal input capability for precise adjustment.

| PTFE | Virgin PTFE is the most widely used sealing material with excellent characteristics suitable for most services. It has excellent chemical resistance throughout valve industries and low coefficient of frication | -20°F – 400°F -29°C – 205°C |
General chemicals, low pressure services |
| RPTFE | RPTFE (Reinforced PTFE) is typically produced by adding 15% fiber glass to virgin PTFE. It has better pressure-temperature properties than virgin PTFE, better resistance to wear and deformation under load. Not to be used in hydrofluroic acid | -20°F – 400°F -29°C – 205°C |
For low and medium pressure services |
| PCTFE | PCTFE is a homopolymer of chlorotrifluoroethylene, featuring high compressive strength and low deformation under load | -320°F – 248°F -196°C – 120°C |
For low temperature low pressure services |
| Nylon | Nylon is a common seat material for Class 600 valves. It is highly resistance to many chemicals and abrasions, and can be used in air, oil and other gas media. It is not suitable for strong oxidization agents | -20°F – 176°F -29°C – 80°C |
For high pressure, low temperature services |
| PPL | PPL (Polyparaphenylene) is an excellent seat material with low coefficient of friction, highly resistant to pressure and temperature | -50°F – 482°F -46°C – 250°C |
For high temperature low pressure services |
| TFM | TFM (modified PTFE) is a chemically modified PTFE that offers enhanced properties while retaining all the proven advantages of a conventional PTFE | -112°F – 248°F -80°C – 120°C |
For services requiring high purity |
| Metal | Metal (typically stellite) seats are used in severe conditions where flashing, hydraulic shock, abrasive media or trapped metal may exist in the line | -320°F – 1202°F -196°C – 650°C |
For severe services |

| NBR | Buna-N (NBR) is an all purpose polymer with good resistance to water, solvents, oil and hydraulic fluids | -50°F – 176°F -46°C – 80°C |
Class 150 – 600 PN 20 – 100 |
| HNBR | HNBR (Hydrogenated NBR) has similar media stability to NBR but with significantly better heat and oxidization stability | -67°F – 337°F -55°C – 170°C |
Class 150 – 600 PN 20 – 100 |
| Viton | Viton (fluorocarbon) is a fluorocarbon elastomer that is compatible with a broad range of chemicals. It performs well in mineral acids, salt solutions, chlorinated hydrocarbons and petroleum oils | -49°F – 320°F -22°C – 204°C |
Class 150 – 600 PN 20 – 100 |
| EPDM | EPDM has good abrasion and tear resistance with excellent chemical resistance to a variety of acids and alkalines. It is susceptible to attack by oil, strong acids and strong alkalines and should not be used in compressed air lines | -50°F – 302°F -46°C – 150°C |
Class 150 – 600 PN 20 – 100 |
