ABSTRACT:
A two way check valve used in a water supply system including a hollow valve body forming a valve chamber with first and second valve seats located in this chamber. The body has an inlet and two outlet ports. A valve or gate member is mounted in the valve body and is capable of pivoting between the first valve seat and the second seat. An elongate coil spring biases the valve member to pivot towards and engage the first seat. Water can flow under pressure from the inlet to a first of the outlet ports but not to the second outlet port. Water can flow in a reverse direction into the first outlet port and is diverted by the valve member out through the second outlet port. The reverse flow is prevented from flowing out the valve inlet.
