Made from Virgin Teflon, this is the most common sealing material; its chemical compatibility is excellent for almost all media. Temperature ---20°C to 225°C.
15% glass reinforced PTFE, suitable for temperature ---20°C to 225°C. Chemical resistance is compatible to virgin PTFE with better wear factor. GLASS REINFORCED PTFE increases the life of valves.
25% Carbon Graphite with 75% PTFE, this material offers a wide temperature range with better wear resistance than standard RPTFE. Good for steam service -20°C to 225°C.
For service with severe flashing, hydraulic shock, high temperature or abrasive media. Typically we hard face a stainless steel seat with Stellite then lap the ball to the seat for tight shut-off. Depending on the valve and trim we can achieve temperatures in excess of 1000° F for metal seated ball valves
This material is very rigid, suitable for high pressure up to 5000psi dependant on valve size and temperature range of -50°F to 180°F.
Best suited for high temperature and pressure service, suitable for tobacco and nuclear service. Temperature -70°F to 550°F.
