Open Type Pendent Water Curtain Nozzle: Build a Moving Fire Safety Barrier
Unlike traditional sprinklers with limited coverage, this open-type pendent water curtain nozzle delivers a 150° ultra-wide spray angle to create a continuous, uniform water curtain barrier. When a fire breaks out, the water stream forms an immediate physical shield to block flame spread, high-temperature radiation, and smoke diffusion, acting as a "flowing firewall" for buildings, warehouses, chemical plants, and more. It achieves dual protection: fire separation and cooling.
Through precision flow channel design, it eliminates common issues like uneven water distribution and weak edge coverage found in conventional nozzles. Whether cooling fire shutters in building atriums or containing flames in warehouse zones, it ensures gap-free protection to prevent fire spread.
Dual K-Factor Options, Tailored to Diverse Engineering Needs
To meet varying project requirements for water pressure, flow rate, and protection levels, we offer two versions: K=0.7 (K70) and K=1.5 (K21.5). The K-factor represents the nozzle's flow characteristics:
K=0.7: Ideal for low-pressure water supply systems, maintaining stable water curtain formation even under low pressure to avoid curtain breaks.
K=1.5: Suited for high-pressure scenarios, delivering high-flow water quickly to build a high-strength protective barrier and block intense heat radiation.
Both versions enable precise flow control for stable, predictable spray performance without extra pipeline adjustments, easily integrating into any fire protection system design.
Universal Thread Interface, Seamless Compatibility with Global Standards
The nozzle features dual thread specifications: R1/2" (BSPT) and 1/2" NPT, fully compatible with mainstream fire protection pipe standards worldwide. R1/2" (BSPT) threads are widely used in Asia and Europe, while 1/2" NPT threads fit North American systems, eliminating the need for custom adapters.
Whether for new construction pre-installation or retrofitting older systems, it enables fast installation and leak-free connections, reducing construction costs and lead times. This makes it a hassle-free choice for international projects adhering to different regional engineering standards.
Dual Material Options + Chrome Plating, Durability for Harsh Conditions
Built to withstand humid, corrosive, and high-temperature environments, the nozzle offers two body material choices:
Brass: Excellent ductility, sealing performance, and precision machining, ideal for standard indoor fire protection applications with cost-effectiveness.
Stainless Steel: Superior corrosion and acid/alkali resistance, perfect for chemical workshops, coastal buildings, underground utility tunnels, and other humid or corrosive settings.
A chrome-plated finish forms a dense protective layer, enhancing corrosion resistance, wear resistance, and oxidation resistance. Even in high-humidity or salt-spray environments, it maintains a pristine appearance and consistent performance, far outlasting ordinary nozzles. This reduces maintenance and replacement costs over its long service life.
Open-Type Pendent Design, Optimized for Critical Fire Scenarios
Engineered specifically for fire separation and water curtain cooling, the pendent design allows water to spray at the optimal angle, eliminating blind spots. Unlike closed sprinklers with thermal-sensitive glass bulbs, the open-type structure responds instantly-no waiting for bulb breakage-to activate immediately during a fire, delivering fast, direct protection for high-risk areas.
Common applications include door/window openings, tunnels, tank farms, and warehouse partition zones. It acts as a water curtain barrier for fire separation or cools high-temperature equipment and building components to mitigate fire spread risks, providing a comprehensive fire safety solution for high-risk
