Flomatic CDP20 1-1/4" Flo-Trol® CDP – Stainless Steel Flow Control Valve (20.0 GPM)

The Flomatic CDP20 1-1/4" Flo-Trol® CDP – stainless-steel automatic flow control valve with a rated flow of 20.0 GPM and 1-1/4" M x 1-1/4" M threaded connections are engineered for reliable, steady flow regulation across varying pressure ranges. NSF/ANSI 61 and 372 certified, the valve is rated for a maximum operating pressure of 200 psi and a maximum temperature of 180°F (82°C).

The CDP series utilizes a flexible Buna-N flow-control orifice with no moving mechanical components. As system pressure increases, the orifice flexes to maintain a consistent flow rate within ±15% between 15 and 125 psi. The full stainless-steel body construction offers excellent corrosion resistance and long service life.

CDP series – All stainless-steel body with NSF 61 approved Buna-N flow-control orifice. MNPT x MNPT threaded connections (ANSI/ASME B1.20.1). Fully automatic constant-flow design with no moving internal parts. Rated 200 psi and 180°F (82°C). Flow tolerance ±15% between 15–125 psi.
