Abstract
A sliding metal seal valve comprises one or more non-circular (oblate) metal seals. Use of non-circular (oblate) sliding metal seals, permits the rotor of a rotary sliding metal seal valve to have a smaller diameter which permits a smaller overall valve size. Reduced rotor diameter also reduces the torque required to turn the rotor, permitting smaller actuator motors to be used. Axially sliding valves such as bar valves may also employ such non-circular sliding metal seals to permit a reduction in the width of such valve.
