Flomatic CDY8.0 3/4" Flo-Trol® CDY – Stainless Steel Flow Control Valve (8.0 GPM)

The Flomatic CDY8.0 3/4" Flo-Trol® CDY – stainless-steel automatic flow control valve with a rated flow of 8.0 GPM and a 3/4" M x 3/4" F threaded connection is engineered to deliver consistent, regulated flow across a wide pressure range. This NSF/ANSI 61 and 372 certified valve is rated for a maximum working pressure of 200 psi and a maximum operating temperature of 180°F (82°C), making it ideal for residential, commercial, agricultural, and industrial applications requiring precise flow control.

The Flo-Trol® CDY series uses a flexible Buna-N flow-control orifice with no moving internal parts. As system pressure increases, the elastomeric orifice flexes to maintain a consistent flow within ±15% between 15 and 125 psi. The 304 stainless-steel valve body provides excellent corrosion resistance, and each valve is laser-engraved with its flow rate and size for easy identification.

CDY series – All stainless-steel body with NSF 61 approved Buna-N orifice. MNPT x FNPT threaded configuration per ANSI/ASME B1.20.1. Fully automatic constant-flow operation with no moving parts. Maximum working pressure 200 psi. Maximum temperature 180°F (82°C). Flow accuracy ±15% between 15–125 psi.
