The low-noise D06 is one of the most popular PRVs on the market, with over 15 million units installed across Europe. The D06FI protects domestic, commercial and industrial applications against excessive water supply pressure. It reduces both water consumption and noise from water hammer, while minimising over pressure damage. The set outlet pressure can be maintained even when there are wide inlet pressure fluctuations. A drop tight seal means outlet water pressure will not increase when there is no flow.

Features:

• Outlet pressure set by turning the adjustment knob
• Set pressure directly indicated on the set point scale
• Adjustment spring not in contact with wholesome water
• Valve insert is of high quality synthetic material and can be fully exchanged
• Integral fine filter (160 microns)
• Available without fittings
• Inlet pressure balancing
• Lightweight
• Drop tight
• Available with pressure gauge

• Screwed Female Ends to IS 554 / BS 21 / ISO 7.
• Piston operated, hence more reliable than conventional diaphragm type PRV.
• Compact size, easy to Install.
• Diaphragm-less, Piston Type.
• Demands low maintenance and virtually noiseless.
• Provided with Premium Quality Nitrile Rubber O Rings.
• Facility provided to install a pressure gauge of 1/4 BSP size to gauge the critically relevant outlet pressure.
• Designed to suit every application requiring accurate pressure ratings.
• All O rings are of superior food grade material, hence ensuring absolute zero health hazard.

Technical Description of Pressure Reducing Valve (PRV)
A Pressure Reducing Valve is a mechanical device that automatically reduces the input pressure of a fluid (gas or liquid) to a pre-set, desired level. They are commonly used in pipelines to control the pressure of water, steam, oil, or gases, ensuring safe operation in systems like HVAC, water treatment, and industrial piping systems.
Key Features:Pressure Control: PRVs are designed to maintain a constant downstream pressure despite fluctuations in the upstream pressure.

• Flow Rate: The valve size and design determine its flow capacity, which varies based on application needs.
• Pressure Adjustment: Some PRVs are adjustable, allowing users to set and fine-tune the downstream pressure according to system requirements.
• Spring-loaded Mechanism: Most PRVs utilize a spring-loaded diaphragm or piston, which adjusts the valve's opening based on pressure changes.
• Bypass Functionality: Some models come with a bypass feature for enhanced system protection.

1. Pressure Range:

   • Inlet (Upstream) Pressure: Typically from 10 bar to 60 bar (depending on the application).
   • Outlet (Downstream) Pressure: Adjustable between 1 bar and 30 bar.

2. Body Material:

   • Common materials include brass, stainless steel, and cast iron, depending on the type of fluid being regulated and the environment.

3. Flow Capacity:

   • PRVs can handle flow rates from a few liters per minute (L/min) to several thousand liters per minute, depending on the size and application.

4. Temperature Range:

   • PRVs can operate in a broad temperature range, from 0°C to 200°C, depending on the materials used and the fluid type.

5. Connection Type:

   • Typically available with threaded, flanged, or welded connections to suit different system requirements.

6. Application Areas:

   • Water Systems: For reducing high water supply pressures to safer levels for household or industrial use.
   • Steam Systems: To control steam pressures, ensuring safe operations in industries like manufacturing, food processing, and energy.
   • Oil & Gas: Used in pipelines to reduce pressure and prevent damage to downstream equipment.
   • HVAC Systems: Regulates water pressure in heating, ventilation, and air conditioning applications.

A Pressure Reducing Valve operates by using a spring-loaded mechanism that controls the flow of fluid. When the upstream pressure rises above the pre-set level, the valve opens to allow fluid flow, and when the downstream pressure reaches the set level, the valve closes. The spring ensures the valve returns to its initial position, allowing the system to maintain a stable output pressure.

• Residential: Protects domestic plumbing systems by maintaining safe water pressure.
• Industrial: Used in large-scale operations to maintain the stability of high-pressure steam or water systems.
