Descriptions Of Powder Pneumatic Actuator Butterfly Valve:
This pneumatic powder butterfly valve is specially designed for the transportation system of dry media such as powders, particles and dust. It adopts a wear resistant structure and is driven by pneumatic power. It is applicable to industries like cement, grain, chemical, and metallurgy. This valve has the characteristics of zero material leakage, low wear, and strict sealing. It can effectively prevent dust leakage, improve the system's operational efficiency, and meet the requirements of environmental protection and automated control.The pneumatic wafer butterfly valve is type of wafer style butterfly valve driven by air actuator. It features compact structure, light weight, easy installation, space-saving for pipelines, and excellent sealing performance. It is widely used for rapid shut-off or regulation of various fluid media such as water, gas, oil, and corrosive substances.

| Material Name |
Description | Operating Temperature |
Service Application |
| 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 |

Air to port A forces the pistons outwards, causing the springs to compress, The pinion turns counterclockwise while air is being exhausted from port B.
Loss of air pressure on port A, the stored energy in the springs forces the pistons inwards. The pinion turns clockwise while air is being exhausted from port A. |
