Flomatic CDC3.0 3/4" Flo-Trol® CDC – Stainless Steel Flow Control Valve (3.0 GPM)

The Flomatic CDC3.0 3/4" Flo-Trol® CDC – stainless-steel automatic flow control valve with a rated flow of 3.0 GPM and 3/4" F x 3/4" F threaded connections is engineered to deliver consistent, controlled 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 suitable for residential, commercial, agricultural, and industrial water systems that require precise flow regulation.

The Flo-Trol® CDC 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 corrosion-resistant 304 stainless-steel valve body and laser-engraved flow markings ensure long-term durability and easy identification in the field.

CDC series – All stainless-steel body with NSF 61 approved Buna-N orifice. FNPT 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.

Operation: Flo-Trol® automatic flow control valves maintain a steady flow rate by using a pressure-responsive elastomeric orifice that flexes under varying system pressures. This non-mechanical design provides smooth, quiet, and maintenance-free performance while ensuring consistent flow even with fluctuating inlet pressures.

Construction: The Flomatic CDC valve body is manufactured from corrosion-resistant 304 stainless steel and paired with a precision-molded Buna-N orifice. Each valve is laser-engraved with flow and size markings for easy identification and verification during installation.

Proud to manufacture high-quality valves built to last since 1933, Flomatic® Valves is an American valve manufacturer certified under ISO 9001 and ISO 14001 quality and environmental management systems.
