ABSTRACT OF THE DISCLOSURE A poppet located in the opening of an annular seat member for use in a body for forming a check valve. The poppet has a resilient seal for engaging a seat formed in the seat member for forming a seal therebetween and which also prevents removal of the poppet from the opening of the seat member. A spring normally urges the poppet in a direction to urge the seal against the seat. The poppet has ribs slidably located in slots formed in the seat member to prevent rotation of the poppet to minimize spring failure. The poppet and seat assembly can be located in the body in either direction to allow the check valve to be used for different purposes. Safety stops are provided in the body for the poppet to prevent shearing of the seal in the event of use in excessive pressure conditions.
