An improved pneumatic valve and a missile with an improved thrust directional valve. In one embodiment, a refractory material lining for a pneumatic valve enables better valve operation and better valve performance. A thin-wall cylindrical sleeve of rhenium or other suitable refractory metal is located inside a cylinder. A valve piston may then travel within the refractory sleeve with greater reliability and better operation. The refractory sleeve cylinder lining can be subject to high temperatures at a rapid rate and remain operational. Under such a hos...
1. A valve for directing propellant thrust, comprising:a refractory cylinder wall lining defining a cylinder symmetrically disposed about a longitudinal axis; and a piston disposed axially relative to the longitudinal axis and configured to slidably move within the cylinder along the longitudinal axis. 2. A valve for directing propellant thrust as set forth in claim 1, wherein the refractory cylinder wall lining is made from metal of the group consisting of rhenium, tungsten, niobium, tantalum, molybdenum, and alloys thereof.3. A valve for directing prop...
