Flojet Pressure Regulator – code: 1616851 – Forniture Nautiche Italiane

Flojet pressure regulator – code 1616851

The Flojet pressure regulator (code 1616851) is an accessory designed for managing the incoming water pressure, useful when you want to maintain a controlled and constant output value. In nautical and plumbing contexts, where supply conditions can vary, a pressure regulator helps protect the system and make the operation of connected utilities more predictable.

This model is designed for limit the outgoing water pressure to 45 psi (3.1 bar), contributing to safer and more stable operation. It is also suitable for handling supplies with maximum inlet pressure up to 10 bar (145 psi), offering a protective barrier against spikes or high pressures coming from the supply line.

Equipped with threaded fittings and a detachable stainless steel filter makes the component practical to integrate into typical installations with standard pipes and fittings, with particular attention to routine maintenance.

Features and construction details

Pressure management

• Maximum output pressure: 45 psi (3.1 bar), for constant water pressure.
• Maximum inlet pressure: 10 bar (145 psi), for protection from high-pressure supplies.
• Function: limits the incoming water pressure to the expected output value, contributing to safer system operation.

Connections and fitting configuration

• Inlet: female thread of 3/4″ for garden hose.
• Filter: detachable stainless steel filter integrated on the inlet side.
• Outlet: male thread of 1/2″.
• Elbow: outlet with 90-degree elbow to facilitate installation in tight spaces or with restricted passages.

Codes and product identification

• Product code: 1616851
• Reference: (former FNI code 1616851)

Typical applications (nautical and plant engineering)

The pressure regulator is a useful component whenever the water supply may present variations or high values compared to those desired downstream. In a nautical context or technical plants, it can be used as a protection and stabilization element of the line.

Freshwater systems and supply lines

• Pressure management on supply lines where it is appropriate to maintain a controlled output value.
• System protection when the inlet pressure may be high or subject to spikes.
• Installations with connection via garden hose on the inlet side and threaded fitting on the outlet side.

Integration with accessories and fittings

Thanks to the configuration 3/4″ female at the inlet and 1/2″ male at the outlet, the component is suitable for insertion in many common configurations. The 90° elbow can be particularly useful when the pipe orientation requires an immediate deviation, reducing the need for additional angled fittings.

Operational advantages

More controlled downstream pressure

The limitation to 45 psi (3.1 bar) allows feeding the line with a defined value, reducing the impact of inlet pressure variations. This helps to make the delivery smoother and maintain consistent working conditions for the connected users.

Protection from high inlet pressures

The ability to manage a maximum inlet pressure up to 10 bar (145 psi) is an important element when the power source can be “pushed” or not perfectly predictable. In these cases, the regulator acts as a control point, helping to preserve the downstream line from unwanted stresses.

Detachable filter for routine maintenance

The presence of a detachable stainless steel filter on the inlet side is useful to retain impurities and particles that could come from the supply line. The ability to remove it facilitates cleaning and periodic checks, especially in contexts where the water or pipe quality may vary.

Simpler installation in technical spaces

The 90° elbow integrated at the outlet helps manage the bulk and orientation of the connection, making installation tidier in technical compartments or at points where the pipe must change direction immediately.

Usage and installation notes

To achieve correct installation and effective pressure management, it is advisable to pay attention to some practical aspects. The following indications are generic and do not replace any specific instructions from the manufacturer or the system.

Positioning in the line

• Install the regulator upstream of the users you want to protect or supply with controlled pressure.
• Check that the inlet side connection corresponds to the 3/4″ female thread for garden hose and that the outlet is compatible with the 1/2″ male thread.

Filter management

• Periodically check the detachable filter and clean it when necessary, especially if the water comes from lines that may carry residues.
• During maintenance, ensure that the system is not under pressure and that the work area is protected from any leaks.

Pressure checks

• If the system requires it, perform a downstream pressure check to confirm the expected output value (45 psi / 3.1 bar).
• In the presence of high inlet pressures, ensure that the upstream line is within the indicated limits (max 10 bar / 145 psi).

Code note

The product is identified by the code 1616851 (also indicated as former code FNI 1616851). To avoid errors when reordering or replacing, it is good practice to always verify the code before purchase.

FAQ – Frequently Asked Questions
