Abstract
A check valve includes a housing having a fluid flow channel therethrough, a valve seat, a clapper, and a pivot link. The clapper is movable between a closed position where the clapper inhibits fluid flow past the valve seat and a fully open position where the clapper permits fluid flow past the valve seat. The pivot link includes a pivot member supported for rotation about a pivot axis, a first arm rigidly connected to the pivot member and coupled to the clapper, and a second arm rigidly connected to the pivot member and coupled to a biasing member. The pivot link transmits a biasing force from the biasing member to the clapper. An effective biasing force that is transmitted to the clapper while the clapper is in the closed position is greater than an effective biasing force transmitted to the clapper while the clapper is in the fully open position.
