Title: Manifold assembly for compressed air storage tank or the like

Abstract: A manifold assembly for a compressed air storage tank or the like having a main flow passage therethrough, ball valve means and pressure relief means. The ball valve means comprises a ball valve member received in a lateral bore extending generally perpendicularly through the passage. The ball valve member has a spherical ball portion with an aperture therethrough and a pair of circular sealing heads, one on each side of the ball portion. Each of the sealing heads carries a seal which is slidably and sealingly engageable with the walls of the lateral bore. The sealing heads are of substantially equal diameter so that pressure forces acting on the ball valve member which tend to move the latter axially within the bore are balanced. A seal body is insertable into a main flow passage of the valve body from one end thereof for sealingly engaging the ball portion after the ball valve member has been installed in the lateral bore.
