ABSTRACT:
A modular valve field convertible between a wet and dry configuration including a valve body and a passage within the valve body for allowing fluid to flow therethrough. A valve seat and clapper are positioned within the valve body. The clapper is allowed to pivot between a first position wherein the clapper is sealingly engaged with the valve seat and a second position wherein the clapper is spaced from the valve seat to allow fluid to flow through the valve. The operator controls the position of the clapper with respect to the valve seat. An operator securely retains the clapper in the first position in a first mode of operation and allows the clapper to freely move between the first and second positions in a second mode of operation. A controller governs the position of the clapper with respect to the valve seat when the operator is in the second mode of operation. The controller has a set position wherein the clapper is maintained in the first position and an activated position wherein the clapper is free to move between the first and second positions.
