Pressure Reducing Valve – ITAP

The ITAP 143 Pressure Reducing Valve is a premium brass pressure regulator engineered to automatically reduce and maintain stable downstream water pressure. Designed for residential, commercial, and industrial plumbing systems, the valve protects pipelines, fittings, appliances, and plumbing fixtures from excessive water pressure, ensuring reliable system performance and extended equipment life.

Manufactured in Italy, the ITAP Model 143 combines precision engineering, corrosion-resistant brass construction, and adjustable pressure settings to deliver consistent water flow, improved plumbing efficiency, and long-term reliability.

What is a Pressure Reducing Valve?

A Pressure Reducing Valve (PRV) is an automatic control valve that reduces high inlet water pressure to a safe and consistent outlet pressure. It continuously monitors downstream pressure and automatically adjusts the internal valve opening to maintain the desired pressure level regardless of fluctuations in the incoming water supply.

Installing a PRV protects plumbing systems from pressure-related damage, minimizes water hammer, reduces water consumption, and improves the lifespan of connected appliances.

Key Features

Automatic Pressure Regulation

The internal spring and diaphragm automatically adjust valve movement to maintain a consistent outlet pressure even when inlet pressure changes.

Adjustable Pressure Settings

The outlet pressure can be adjusted to suit different plumbing systems and operating requirements, providing precise pressure control for optimal performance.

Premium Brass Construction

Manufactured using high-quality forged brass, the valve offers excellent mechanical strength, corrosion resistance, and durability under continuous operating conditions.

Protects Plumbing Equipment

Stable water pressure helps protect pipes, fittings, faucets, water heaters, washing machines, and other plumbing fixtures from excessive pressure damage.

Leak-Resistant Performance

Precision-machined internal components provide reliable sealing while maintaining smooth water flow throughout the plumbing network.

Easy Installation

The compact valve body allows quick installation into new or existing plumbing systems with minimal maintenance requirements.

How Does a Pressure Reducing Valve Work?

The ITAP Pressure Reducing Valve uses a spring-loaded diaphragm mechanism to continuously balance inlet and outlet pressure.

1. High-pressure water enters the valve.
2. The diaphragm senses downstream pressure.
3. The spring controls valve opening.
4. The valve automatically regulates water flow.
5. Constant outlet pressure is maintained.
6. The plumbing system receives safe, regulated water pressure.

Installation Guide

1. Turn off the water supply.
2. Install the valve in the correct flow direction.
3. Connect the valve using suitable threaded fittings.
4. Install a pressure gauge if required.
5. Restore the water supply.
6. Adjust the outlet pressure using the adjustment screw.
7. Check all connections for leakage.

Professional installation is recommended for maximum efficiency and long-term performance.

Pressure Adjustment

The ITAP Model 143 allows easy pressure adjustment by rotating the adjustment screw. Increasing spring compression raises outlet pressure, while reducing spring compression lowers outlet pressure to match system requirements.

Maintenance

• Inspect the valve periodically.
• Check inlet and outlet pressure.
• Clean strainers if installed.
• Inspect fittings for leakage.
• Verify pressure settings annually.
• Replace worn sealing components when necessary.

Frequently Asked Questions

What is the purpose of a Pressure Reducing Valve?

A pressure reducing valve automatically lowers high inlet water pressure to a safe and constant outlet pressure, protecting plumbing systems and connected equipment.

How does a Pressure Reducing Valve work?

It uses a spring and diaphragm mechanism to continuously monitor downstream pressure and automatically adjust the valve opening to maintain stable water pressure.

Where should a PRV be installed?

A pressure reducing valve is typically installed on the main water supply line before water enters the building’s plumbing system.

Can the outlet pressure be adjusted?

Yes. The ITAP Model 143 features an adjustable pressure mechanism that allows users to set the desired outlet pressure.

Does a PRV prevent water hammer?

Yes. Maintaining consistent water pressure significantly reduces pressure surges and minimizes the risk of water hammer.

How long does a Pressure Reducing Valve last?

With proper installation and periodic maintenance, a high-quality brass PRV can provide many years of reliable service.
