Abstract: An anti-drain valve for a plate cooler comprises a plastic housing having a generally cylindrical outer wall with open ends, and an inner support structure integrally formed therewith, and with a valve seat. A piston is located within the support structure and axially movable toward and away from the valve seat. A biasing member biases the piston toward the valve seat. A resilient sealing element provides a seal between the housing and the base plate. The outer wall comprises first and second portions, the first portion including a plurality of inwardly bendable detents defined by slots through the outer wall for attaching the valve to the base plate of the plate cooler.
