Dry Pipe Sprinkler System is a crucial fire protection solution for areas where freezing temperatures could affect traditional wet pipe systems. These systems keep the pipes filled with air or nitrogen, ensuring that water flows only when a fire is detected. In this article, we will dive into the features and benefits of the Reliable Model EX Low Pressure Dry Pipe Valve, which enhances the performance of dry pipe systems.

Dry Pipe Sprinkler System Overview

Dry pipe systems are ideal for cold environments. Unlike wet pipe systems, where water is always present, dry pipe systems store air or nitrogen in the pipes. When the system detects fire, the pressure is released, allowing water to flow and extinguish the flames.

Advantages of Dry Pipe Sprinkler Systems

1. Prevents Freezing: Dry pipe systems prevent water from freezing in the pipes, making them perfect for cold environments like warehouses or parking garages.
2. Delayed Water Release: These systems have a slight delay in water discharge, which is essential for areas where freezing temperatures could be an issue.
3. Perfect for Cold Areas: Dry pipe systems are especially useful in buildings that experience low temperatures, such as industrial facilities or unheated spaces.

Reliable Model EX Low Pressure Dry Pipe Valve

The Reliable Model EX Low Pressure Dry Pipe Valve is a hydraulic-operated, mechanical latching clapper-type valve. It serves as the primary control valve in dry pipe systems. This valve operates at a much lower pneumatic pressure than conventional dry pipe valves, offering several key advantages.

Benefits of the Reliable Model EX Valve

1. Lower Pneumatic Pressure: The Model EX valve works at a lower pneumatic pressure, ranging from 8 to 28 psi (0.6 bar to 1.9 Bar). This provides several advantages:
   • Smaller and more affordable pneumatic sources.
   • Faster water flow after valve activation.
   • No need for quick opening devices in some cases.
   • More cost-effective use of nitrogen.
2. Improved Reliability: The Model EX valve is less prone to accidental tripping, making it more reliable than conventional differential valves.
3. No Priming Water Needed: This valve design does not require priming water, simplifying installation and maintenance.
4. Faster Setup: The external reset mechanism helps reduce setup and commissioning time.
5. Durable and Compact Design: The valve features a light ductile iron body and compact trim, ensuring durability and easy installation.

Available Sizes

The Reliable Model EX Low Pressure Dry Pipe Valve comes in the following sizes:

• 2″ (50mm)
• 2 1/2″ (65mm)
• 3″ (80mm)
• 4″ (100mm)
• 6″ (150mm)
• 8″ (200mm)

These sizes allow for flexibility and customization in your dry pipe system.

Features of the Low Pressure Dry Pipe Valve

• Low Air or Nitrogen Pressure: The valve operates at a range of 8 to 28 psi (0.6 bar to 1.9 Bar).
• Compact and Durable: The ductile iron body ensures a long-lasting design.
• Quick Setup: The external reset mechanism streamlines the installation process.
• No Need for Priming Water: Simplifies system installation.
• Customizable Configurations: The valve is available fully assembled or with an optional control valve.

Conclusion

The dry pipe sprinkler system is an essential fire protection solution for buildings in cold environments. The Reliable Model EX Low Pressure Dry Pipe Valve improves system performance by operating at a lower pneumatic pressure, offering faster water flow and enhanced reliability. With its light ductile iron body, external reset, and no need for priming water, this valve ensures efficiency and ease of installation.

The Model EX valve is ideal for warehouses, parking garages, and other facilities that require a dry pipe system. By choosing the Reliable Model EX valve, you invest in a more cost-effective, reliable, and durable fire suppression system.
