Deluge Valves & Systems

Deluge Valves & Systems

We are a reputed Deluge Valve manufacturer known for providing deluge valves with robust and reliable design. These are used in areas where fires necessitate speedy and rigorous control. In the most critical situations, our deluge valve successfully releases large volumes of water as a rapid response. Deluge Valves are provided with suitable trims – wet pilot, dry pilot, remote electric, manual release trims, etc. providing all necessary options for quick actuation.

What is a deluge valve?

HD Deluge Valves are quick-acting, differential diaphragm-type valves designed specifically for critical fire protection systems. These play an important role in controlling water flow in deluge, pre-action, and foam-based fire protection systems. By maintaining system piping and outlet chambers dry, the deluge valve ensures readiness and rapid activation during emergencies. In fire scenarios, the releasing mechanism activates, relieving pressure in the priming chamber and instantly opening the deluge valve.

HD Deluge Valves are manufactured from high-quality materials, including cast iron, ductile iron and nickel aluminium bronze, ensuring durability and adaptability for various system configurations. They are compatible with open sprinkler systems and can be mounted in either horizontal or vertical orientations. Available trims include wet pilot, dry pilot, electric release, manual release, and more, offering flexibility for diverse applications. For high-risk environments, these valves can be skid-mounted for targeted fire protection.

Our deluge valves are UL-listed, incorporating advanced heat or smoke detection systems for reliable operation. They are ideal for power plants, industrial facilities, and large-area hazards, providing rapid water or foam coverage through open nozzles.

To ensure optimal performance, HD deluge systems can be integrated with hydraulic and electric controls. Detailed specifications, operating principles, and ordering information are available in our product catalogue.

FAQ

What is a deluge valve and how does it work?

A deluge valve is a quick-opening, diaphragm-operated valve used in fire protection systems that require rapid water or foam discharge. It remains closed until triggered by a detection device (heat, smoke, or manual), after which it instantly releases water through open nozzles.

Where are deluge valves used?

Deluge valves are ideal for high-risk environments such as power plants, transformer rooms, chemical facilities, aircraft hangars, and refineries—where immediate fire suppression is critical.

What are the types of trims available for deluge valves?

Deluge valves come with various trim options, such as wet pilot, dry pilot, electric release, and manual release. Each supports a specific activation method suited to the facility’s fire safety system.

Can deluge valves be used with foam systems?

Yes, deluge valves are compatible with foam-water systems. Foam concentrate is mixed with water before discharge, making them effective for combating flammable liquid fires.

What certifications do your deluge valves carry?

Our deluge valves are UL-listed, ensuring compliance with global standards, including requirements from Civil Defense authorities and clients such as Saudi Aramco.

What is the purpose of a deluge system?

Its purpose is to flood a hazard area with large volumes of water or foam to suppress or control a fire immediately upon detection.

How is a deluge valve system activated?

Activation occurs via heat or smoke detectors, manual pull stations, or electric signals. These mechanisms release pressure from the priming chamber, causing the valve to open.

What is the typical pressure range of a deluge valve?

Deluge valves typically operate between 7 and 12 bar (100–175 psi), depending on the system design and application. While our deluge valves are rated to maximum operating pressure of 17.2 bar (250 psi).

How do you manually operate a deluge valve?

Manual operation is performed using a manual release station to depressurize the priming chamber, which opens the main valve.

Why is a deluge valve important in fire protection?

It ensures immediate and widespread fire suppression, especially in high-hazard zones where fire spread must be contained instantly.

Do you supply deluge valves to Southeast Asia and the Middle East?

Yes, we export deluge valves to countries such as Indonesia, Vietnam, Singapore, Malaysia, Philippines, Thailand, Saudi Arabia, Qatar, Colombia and Brazil. Our products are supported with complete export documentation, HS codes, and compliance certificates.

Are your deluge valves compliant with local regulations?

Absolutely. Our UL Listed valves meet international fire safety standards and are approved for use by Saudi Aramco, Qatar Civil Defence, and regulatory bodies in various countries.

Do you offer technical support for international projects?

Yes, we provide assistance with valve sizing, documentation, compliance, and system integration for projects in manufacturing zones, oil & gas plants, commercial buildings, and many other sites across these regions.
