Claim:
1. A venting valve for releasing gases entrapped within the valve, the venting valve comprising: a) a housing having a lower opening for the entry of media and gases, and an upper opening for exit of gases; b) a float located within the housing, the float connected to a float shaft, the float shaft in mechanical communication with: wherein the buildup of liquids within the housing causes the float and float shaft to rise, the rising float shaft raises the second sealing member until it makes contact with the main disc of the first sealing member, and upward force from the second sealing member raises the main disc of the first sealing member until the first sealing member and second sealing member close; wherein upon subsequent buildup of gases within the housing, some of the gases flow into the piston cylinder through the piston orifice to accumulate in the piston cylinder, accumulation of gases in the piston cylinder causes the piston to move downward, and the movement downward of the piston causes the second sealing member to move downward and to open without opening the first sealing member such that gases can escape past the second sealing member and out of the valve housing while the first sealing member remains sealed; and wherein upon release of gases within the housing past the second sealing member the float rises until the second sealing member returns to a closed position in contact with the main disc, with the piston moving upward with the upward movement of the second sealing member.
