Abstract
A valve is disclosed for use in hot gas applications such as in rocket or missile engine systems or the like. The valve is designed to withstand the extreme temperatures encountered in the gas exhaust from rocket propellants. The valve seat of the valve is constructed of fibrous monolith ceramic. This material does not degrade significantly when rocket exhaust, such as resulting when ammonium perchlorate propellant is burned, is ported through the valve. The valve generally includes a valve body, a valve seat, through which gases may pass, and a poppet which opens and closes the valve by pressing against and moving away from the valve seat.
