ABSTRACT:
A clapper-type check valve has a valve body with a chamber therein and a clapper-type valve member is mounted on an arm pivotally supported in the valve chamber. The valve member is supported from the lower end of the arm about a support pin received in openings in a pair of spaced lugs on the rear face of the valve member. An elastomeric bushing fits within each of the lug openings around the pin to permit a dampened and limited relative movement between the arm and the valve member. A channel-shaped strap is secured to the rear face of the valve member and receives a mid-portion of the arm. A band of elastomeric material is bonded around the arm between the valve member and the strap to permit a dampened and limited relative movement between the arm and the valve member.
