High Temperature Ball Valve
Platinum valve high temperature floating ball valve apply the metal-to-metal seat like metal retainer with TCC or STL to promote it durability and sealing performance under extremely high temperature. Because the soft sealing component like o-ring or lipseal can not endure under such high temperature,consequently, it will be ineffective and can not achieve sealing performance. Our team will select the most suitble flow solution for you.

FAQ
Q: How to select materials of seat insert?
A: In common condition, we will quote as your material requirements. If the seat insert our clients select is not suitable for your working condition(medium, temperature, pressure), we help you to change the suitable one for you. The working medium will directly touch with seat insert and working temperature and pressure will impact the sealing performance of seat insert, so our technical team will choose the most fittable material of seat insert for you based on it working condition. Below 150#, PTFE. 150# to 600# RPTFE. 600# to 900# Delvon. 900# to 1500# Devlon or Nylon. 2500# PEEK.
Q: What is API 6D?
A: API 6D is an international standard formulated by the American Petroleum Institute (API) specifically for valves used in pipeline systems of the oil and gas industry. The standard indicate the comprehensive requirements in the aspects of design, production, inspection, test, which provide the important reference for guarantee of quality and safety of valves.
Q: What is difference between high temperature and normal temperature ball valve?
A: Under high temperature ball valve, the mechanical property of material will be greatly impacted. And the structure of ball valve also will be different from normal temperature. Due to the internal soft seal material like o-ring, lip seal will be ineffective under high temperature. Our design team recommend to apply metal-to-metal seat,like TCC OR STL Coat,or welding metal material on sealing area where will touch the wet medium.
