Ball Valve Seats
Ball Valve Seats
(OP)
Hello,
My company is looking at design a ball valve using Peek seats. Typically up to 2" size and 7000 psi at 400 deg F maximum. We are having trouble sealing the valve using seats contoured to the ball. Is there a special Peek compound that we should be looking at? Should we be lapping the seats? What is a good lapping compound?
Thank you,

My focus is on corrosion-resistant, high-alloy valves for the petrochemical industry.

Also, are you set in having a spherical sealing surface? You may get better results from a edge seal.

Plus I don't want the Chinese industrial knowledge thieves to see it.
