Boshart CDX Series 1" FPT Stainless Steel Flo-Trol Flow Control Valve

The Boshart CDX Series Flo-Trol flow control valve is a 1" FPT stainless steel valve engineered to deliver a constant flow rate across a wide range of supply pressures, based on the Flomatic Flo-Trol CD900 flow control valve platform. The CDX Series is available in two models — CDX5.0 and CDX8.0 — covering constant flow rates from 5 GPM up to 8 GPM, so contractors can match the valve to the flow requirement of the specific application. Built with a self-cleaning flexible orifice rather than any moving parts, each CDX Series valve automatically adjusts its opening size as line pressure changes to hold flow steady, making it a reliable rough-in component for well systems, pressure tanks, and other plumbing applications where consistent flow matters. Manufactured in the United States, the Boshart CDX Series valve is a straightforward, low-maintenance solution for contractors who need dependable flow regulation without adjustable settings or serviceable internals.

Key Features

  • Trade Size: 1" FPT connection for direct threaded installation into water supply piping.
  • Flow Rate Range: Model options deliver a constant 5 GPM (CDX5.0) or 8 GPM (CDX8.0) regardless of pressure fluctuations upstream.
  • Durable Construction: Stainless steel (S.S.) body resists corrosion in continuous water service.
  • No Moving Parts: Self-cleaning flexible orifice varies size with applied pressure to maintain a steady flow rate, reducing wear points and maintenance needs.
  • Wide Pressure Range: Designed to give constant flow across a wide range of supply pressures, per manufacturer tech data.
  • CDX Series Design: Based on the Flomatic Flo-Trol CD900 flow control valve platform.
  • Larger Sizes Available by Special Order: 3" MPT models (CDK series) are available by special order; contact sales for details.

Technical Specifications

  • Model Options: CDX5.0 (5 GPM), CDX8.0 (8 GPM)
  • Country of Origin: USA
  • Prop 65 Warning: Lead

Typical Applications

  • Residential and Commercial Rough-In Plumbing

Boshart CDX8.0 – Frequently Asked Questions

1) Which flow rate should I order for the Boshart CDX Flo-Trol valve, 5 GPM or 8 GPM?
The CDX Series comes in two fixed flow rates and neither is adjustable, so pick the one that matches the design flow of the system. Model CDX5.0 holds a constant 5 GPM and CDX8.0 holds a constant 8 GPM. There is no field setting, so sizing happens at the order stage: match the valve to the pump or fixture flow requirement, not to the pipe size.
2) What size and type of connection does the Boshart CDX flow control valve have?
It is a 1 inch FPT valve, meaning female threaded on both ends for direct threading into 1 inch water supply piping. No adapters, unions, or solder work are part of the valve, so if your line is copper or PEX you will need male-thread transition fittings on each side.
3) Is a Flo-Trol flow control valve the same thing as a pressure regulator?
No, and they solve different problems. The CDX Flo-Trol holds the flow rate constant (5 or 8 GPM) as supply pressure varies upstream. It does not set the downstream pressure. If you need to cap system pressure, you still need a pressure reducing valve; if you need to keep a well pump from overdrawing a low-yield well, the flow control valve is the right part.
4) Will a 1 inch Flo-Trol flow control valve fit in a tight pressure tank rough-in?
It is a compact inline body, 1.6 inches wide and 1.5 inches high at 0.7 pounds, so it drops into a tank tee run or a well line without bracing or extra support. Allow room for a wrench on the hex when threading it in.
5) Does the Boshart CDX Flo-Trol valve need maintenance or have parts that wear out?
No. The CDX Series works off a self-cleaning flexible orifice that changes shape as line pressure changes, so there are no moving parts, no serviceable internals, and nothing to adjust. That also means it cannot be rebuilt: if it ever fails it gets replaced, not repaired.
6) Is the Boshart CDX valve body corrosion resistant enough for continuous well water service?
The body is stainless steel, which is why it is specified for continuous water service in well systems and pressure tank installations rather than a plated brass or plastic flow restrictor. It is made in the United States.
7) I need a flow control valve larger than 1 inch, does Boshart offer one?
The CDX Series itself is 1 inch FPT only. For larger work, Boshart's CDK series in 3 inch MPT is available by special order through sales.
8) Is the Boshart CDX Flo-Trol a replacement for a Flomatic CD900?
The CDX Series is built on the Flomatic Flo-Trol CD900 flow control valve platform, so it is the same style of no-moving-parts flexible orifice device. Match on connection and flow when swapping: the CDX is 1 inch FPT in 5 GPM and 8 GPM.
9) Does the Boshart CDX flow control valve carry a Prop 65 warning?
Yes, it carries a California Prop 65 warning for lead. Institutional and municipal buyers working to potable-water purchasing rules should factor that into their approval process before specifying it.
