ABSTRACT:
An automatic fluid flow control valve and strainer device which provides a constant flow rate of strained fluid despite varying differential pressures and employs a combination of a unitary body with an integrated, removable strainer assembly and a removable flow control valve assembly. The body is essentially in the shape of a "Y" and provides a compact valve with minimum threaded joints and access to the various components thereof with minimum disassembly. The removable strainer assembly is configured and arranged in a manner so that fluid flows from the outside to the inside of a cup-shaped strainer, allowing easier use and cleaning.
