<p>A check valve comprises a spring biased poppet reciprocally mounted in a housing thereof to normally close an inlet to the valve. A set screw is threadably mounted in an exposed position on the housing to selectively vary the spring load on the poppet to thus vary the pressure setting thereof. An annular elastomeric locking member circumvents the set screw and is compressed radially inwardly thereagainst by a clamping member, releasably attached on the housing, to retain the set screw in its preset position.</p> |
