Fire Protection Valves

Fire protection valves are vital components used to ensure the safe, controlled and efficient operation of firefighting systems. Directing and controlling water flow and supporting the automatic response of the system, these valves play an active role in all types of fire installations. Deluge valves, alarm valves, pressure relief valves and gate valves offer solutions suitable for every risk level thanks to their different types. Mirsa Market offers safe infrastructure support to businesses with durable and certified valve models that are fully compatible with fire installation systems.

Deluge Valves: Rapid Response Solution in High Risk Areas

Deluge valves are rapid intervention focused fire protection systems used in industrial facilities with high fire risk, especially in environments where explosive or flammable materials are present. These valves work integrated with the fire detection system and activate all sprinkler heads simultaneously with the signal from the fire sensors, providing high flow water flow in large areas. Deluge models, which are among the fire protection valves preferred especially in places requiring critical security such as oil refineries, power plants, aircraft hangars and chemical storage areas, play a key role in controlling the fire in a short time. These systems, suitable for transferring water, foam or special extinguishing agents, are manufactured with special materials against high heat and pressure. Mirsa Market offers special solutions for projects with deluge valve models that provide high pressure resistance, corrosion resistance and long-lasting performance. The fact that the products have passed the leakage tests is a guarantee of a safe intervention process.

Automatic Intervention in Case of Fire with Wet and Dry Alarm Valves

Alarm valves work as the triggering component of automatic fire extinguishing systems and regulate the entry of water into the system, thus starting the intervention process. Wet alarm valves constantly keep water in the pipeline and provide instantaneous water flow with the explosion of sprinkler heads when a fire starts. These systems are preferred in indoor areas where there is no risk of frost, especially in areas such as commercial buildings and hotel lobbies. On the other hand, dry alarm valves are systems that contain air or nitrogen in the pipe and are used in areas where there is a risk of frost. In the event of a fire, the air is released by opening the sprinkler head, the pressure in the system decreases and the valve releases water. Both types are included in the fire protection valve family and increase the efficiency of the system according to the area of use. Alarm valves offered by Mirsa Market eliminate the risk of water leakage and provide ease of installation thanks to their sensitive detection sensors and durable seal systems. Especially with models with EN and UL certificates, both safety and long-term performance are guaranteed.

Pressure Relief Valves: Protection Against Excess Pressure in the System

Pressure relief valves are safety equipment that are activated against sudden and high pressure increases that the fire installation may be exposed to. These valves prevent damage to other parts of the installation by ensuring that the water is discharged in a controlled manner. In high-rise buildings, pressure fluctuations that may occur due to sudden water flow may cause pipe bursts, leaks at connection points or valve damage in the system. Pressure relief valves, which play a role in balancing such in-system pressures among fire protection valves, extend the life of the system while also increasing operational safety. Mirsa Market offers relief valves that can operate in different diameters and pressure ranges and open and close with high precision. These products open automatically when exposed to excessive pressure and close leak-proof after the risk has passed. The stainless body structure provides superior performance even in difficult field conditions. It is indispensable in terms of safety, especially in critical areas such as hospitals, data centers and high-rise buildings.

Flow Control with Rising Stem Gate Valves (RS&R)

Rising stem gate valves (RS&Y) are special valve types that provide manual flow control in fire installations and allow visual monitoring of whether the system is open or closed. The upward or downward movement of the stem in these valves allows the position of the valve to be observed from the outside. These valves, which provide great convenience especially in maintenance and testing processes in fire systems, not only meet the manual control needs of the system; they also provide information about the status of the system to the intervention teams. They are especially located in the main line of the water source or at critical distribution points among fire protection valves. They are suitable for difficult field conditions with their robust cast bodies, high torque resistance and stainless internal parts. RS&Y valves offered by Mirsa Market are included in the security infrastructure of many structures from industrial facilities to large residential projects. These valves are manufactured in full compliance with fire regulations and offer great advantages in terms of transparent management of fire systems.
