Sep 22, 2011 · Increasing the width of the valve seat is an effective method of increasing heat transfer, but this can have a significant negative effect on flow coefficients, and seat contact widths are generally kept to a minimum for this reason. The use of high thermal conductivity valve seat materials is another effective way of increasing heat transfer.
Oil and Gas plastic solutions EnsingerTypical applications such as hydrophone housing, seals, valve seats, back-up rings, bushings and gears can benefit from the weight reduction, corrosion resistance, thermal de-coupling and minimized noise emissions provided by these materials.

Transient Thermal Analysis of Engine Exhaust Valve Nov 18, 2020 · The valve warm-up time is largely determined by the effective thermal inertia of the valve (valve body plus 1/3 of stem mass) and the thermal resistance to the seat. The valve Plasma/thermal sprayed valve seats - High Power MediaThe subject of valve seat materials has been dealt with in RET-Monitor before; an article published in 2012 briefly discussed the requirements for seat materials. There are several important requirements for a valve seat material. It is generally responsible for the vast majority of heat transfer from the poppet valve, it needs to be strong enough not to be deformed by the action of the valve
