Dilution Solutions Flow Restrictor, 3/4 in 14 GPM (D14 Series)

3/4 Inch Flow Restrictor for Dosatron D14 Series, 14 GPM – FR34-14GPM

The Dilution Solutions FR34-14GPM is a 3/4-inch flow restrictor for Dosatron D14 series proportional injector installations. The D14 series Dosatron units have a higher maximum flow rating than standard Dosatron units, requiring a flow restrictor that limits flow to 14 GPM rather than the 10 GPM of the FR34-10GPM.

Like the FR34-10GPM, the FR34-14GPM installs on the inlet side of the Dosatron unit and prevents water flow rates from exceeding the injector's maximum rated capacity. When selecting a flow restrictor, match the restrictor's GPM rating to the specific Dosatron model installed in the system. Installing a 10 GPM restrictor on a D14 series unit would unnecessarily limit flow below the unit's capacity.

Key Features & Benefits

• 14 GPM Flow Limit — Restricts inlet flow to 14 GPM for Dosatron D14 series units.
• 3/4-Inch Connection — Sized for 3/4-inch Dosatron D14 series inlet connections.
• D14 Series Specific — Rated for the higher maximum flow capacity of Dosatron D14 series injectors.
• Inlet Side Installation — Installs upstream of the Dosatron unit on the inlet side.
• Overflow Prevention — Prevents flow rates from exceeding the D14 series injector's maximum rating.
• Dosatron NDS Compatible — Designed for use in Dilution Solutions NDS systems with D14 Dosatron injectors.

Who Should Use This Restrictor

The FR34-14GPM is required for Dosatron D14 series installations where the water supply pressure could drive flow above 14 GPM through the injector. Confirm the Dosatron model in the system before selecting between the FR34-10GPM and FR34-14GPM — using the wrong restrictor will either over-restrict the D14 (10 GPM restrictor) or under-protect a standard unit (14 GPM restrictor).

Identifying the Correct Flow Restrictor for Your Dosatron Model

Dosatron injectors are available in multiple series, each with a specific minimum and maximum flow rate range. The D14 series has a higher maximum flow rating than the standard D series. The flow restrictor must match the maximum rated flow of the specific injector installed. Using a 10 GPM restrictor on a D14 unit that can handle 14 GPM will reduce the system's irrigation throughput below what the injector is designed for. Using a 14 GPM restrictor on a standard unit that maxes at 10 GPM provides no protection at flow rates between 10 and 14 GPM.

Frequently Asked Questions

What Dosatron models is the FR34-14GPM for?

The FR34-14GPM is designed for Dosatron D14 series injectors with a 14 GPM maximum flow rating.

What is the difference between FR34-10GPM and FR34-14GPM?

The FR34-10GPM limits flow to 10 GPM for standard Dosatron units. The FR34-14GPM limits flow to 14 GPM for Dosatron D14 series units.

Where is the flow restrictor installed?

On the inlet side of the Dosatron unit, upstream of the injector.

What happens if the flow restrictor GPM rating doesn't match the injector?

A restrictor rated too low will unnecessarily limit flow through the injector. A restrictor rated too high will not protect the injector from overflow at elevated flow rates.
