Industrial Valves for Fire Fighting

Fire protection systems are vital for safeguarding lives and property, requiring valves that ensure reliability and integrate seamlessly with fire alarm devices for a comprehensive, monitored extinguishing system. These systems demand high-pressure resistance and exceptional sealing performance to prevent overpressure pipe explosions. They also mitigate water hammer damage and noise, while certain valves provide position monitoring for enhanced control. Together, these features ensure the system's safety, efficiency, and resilience in critical fire protection applications.

Typical firefighting applications of Arrowhead Industrial Valves

Water Tank Replenishment Valve Group

Application Description

The water replenishment tank is designed to automatically refill water by incorporating a solenoid-controlled float valve into the water supply pipeline. When the water level in the tank falls below the preset level, the solenoid-controlled float valve automatically opens to replenish the water. Once the water level reaches the designated set point, the valve closes, halting the replenishment process.

Water Tank Replenishment Valve Group

A106 Solenoid Control Floating Valve

Dual Control System: Combines electronic float switch and mechanical float switch for enhanced reliability.
Electronic Float Switch: Controls water replenishment based on liquid level signals.Solenoid valve opens when the water level is low, and closes when the water level is high.
Mechanical Float Switch: Automatically triggers to stop water replenishment in case of solenoid valve failure or abnormal water level rise.

Fire Fighting Pump Station Water Supply Valve Group

Application Description

Issues like water hammer and pressure imbalances often arise in fire fighting systems. High-performance check valves solve water hammer caused by pump stoppage. Adjusting valve closing times can also reduce water hammer during pump shutdowns. Ultra-high pressure generated at low flow must be relieved to protect the system. Bypass pressure relief valves should maintain zero leakage when the pump stops. Regular cleaning is essential to prevent equipment damage from pipeline debris, and valves require routine maintenance to ensure optimal performance.

RVRX Fire Fighting Rising Stem Gate Valve

Straight Flow Channel Design: Ensures optimal flow with minimal resistance.
Fully Vulcanized Valve Wedge: Coated with EPDM rubber for durability and performance.
Low Torque Performance: The valve wedge includes a plastic guide slider for reduced operating torque.
High-Strength Valve Stem: Manufactured using a rolled processing method, offering higher strength and lower torque.
Shaft Seal Design: Features three "O-ring" seals for reliable sealing performance.
Inverted Back Seat Seal: Allows for online maintenance and repair without system shutdown.

Fire Fighting Pressure Reducing Valve Group

Application Description

A pressure-reducing valve is installed on the water supply pipeline to stabilize pressure behind the valve, regardless of flow rate or fluctuations in upstream pressure. It helps reduce static pressure and ensures consistent water supply pressure. Optional features include intelligent pressure management and a valve cartridge disc to enhance cavitation resistance, enabling the valve to meet higher pressure reduction requirements. This setup ensures reliable and efficient pressure control across different water supply areas.
