Abstract

The valve has a body which has integral inlet and outlet connections (2, 3). The valve has an upper closed chamber. The valve has two seats and is controlled by a rod. The end of the rod fits into a bayonet fitting. The outside wall of the cylinder has two pins diametrically opposed. The valve is operated by a downwards movement of the rod.
