ABSTRACT:
An in-line check valve includes a housing defining a cavity with an inlet and an outlet, a removable seat attachable to the inlet, a piston movably positioned in the housing and including a seal that operably engages the seat, and a spring positioned around the piston for biasing the piston into engagement with the seat. The piston defines a surface impinged on by fluid flowing therethrough so that the differential pressure across the valve in a given flow range is less than the opening pressure. The housing defines a plurality of lugs which retain the piston within the housing and permit servicing of the seal.
