CA-Fire K5.6 Series Brass Fire System Drain Valve

(Multi-Function Drain & Test Valve for Fire Pipeline Maintenance & Freeze Prevention)

 

1. Product Name & Positioning

 

Full Name: CA-Fire K5.6 Series Brass Fire System Drain Valve (H59-1 Brass Material, OFF/TEST/DRAIN Three Gears, 1.6MPa Working Pressure, DN15 Caliber, CCC Certified)

Abbreviation: CA-Fire K5.6 Brass Fire Drain Valve

Core Positioning: A specialized brass drain/test valve for fire protection systems-completely different from all previous water guns/nozzles (fire suppression tools). It serves three core functions: pipeline drainage,pressure testing and winter freeze prevention, designed exclusively for fire pipelines,wet alarm valve groups,sprinkler systems and hydrant networks. With full brass corrosion resistance,K5.6 flow coefficient and one-hand operation, it solves the "pipeline maintenance inefficiency" and "freeze damage" problems of generic valves-ideal for commercial buildings,industrial fire systems,residential complexes and fire maintenance teams.

 

2. Core Product Advantages

 

1. Full Brass Construction: Corrosion-Resistant for Fire System Environments

Made of high-quality H59-1 brass, tailored for long-term contact with water/foam mixtures:

Brass body + internal components (valve core,seal,gear switch) resist rust,scale and chemical corrosion (compatible with fire foam concentrates). Passes 800-hour salt spray tests, suitable for humid,coastal or industrial fire systems-service life up to 15-20 years, far exceeding iron or plastic valves.

Brass thermal conductivity ensures no brittle fracture in low temperatures (-20℃~+60℃), avoiding freeze damage to valves in winter.

2. Three-Gear Design (OFF/TEST/DRAIN): One Valve for Multiple Maintenance Needs

Integrates three functions, eliminating the need for separate valves:

OFF Gear: Closed state, isolating the drain valve from the fire pipeline during normal operation.

TEST Gear: Low-flow drainage for system pressure testing (e.g., verifying wet alarm valve sensitivity,pipeline pressure stability) without full pipeline drainage.

DRAIN Gear: Full-flow drainage for pipeline maintenance (e.g., flushing impurities),winter freeze prevention (draining residual water) or emergency water release-K5.6 flow coefficient ensures fast drainage (≥5L/min for DN15 caliber).

3. Easy Operation & Installation: Low Maintenance for On-Site Teams

Designed for efficient on-site use:

Rotating brass gear switch (OFF/TEST/DRAIN clearly marked) enables one-hand operation, no professional tools required-maintenance staff can complete operations in 1 minute.

Compact structure (DN15 caliber) with standard threaded connection, compatible with most fire pipeline interfaces (e.g., wet alarm valve outlets,sprinkler system branch pipes). Installation takes ≤10 minutes, supporting both horizontal and vertical mounting.

4. Compatible with Fire System Ecosystem

Seamlessly matches common fire equipment:

Suitable for fire pipelines,wet/deluge alarm valve groups,sprinkler systems and hydrant networks, compatible with CA-Fire's AFFF foam systems,fire hydrants and sprinkler heads.

Works with clean water and 3%/6% foam mixtures, no impact on system sealing or water quality-meets CCC fire product certification standards.

5. Durable & Leak-Proof: Reliable for Critical Maintenance

Focus on long-term stable performance:

Precision-machined brass valve core + nitrile rubber seal ensures zero leakage under 1.6MPa working pressure, even after 5,000+ gear switches.

Reinforced brass thread and gear structure resists wear from frequent operation, avoiding valve jamming or failure during emergency drainage.

4. Applicable Scenarios

 

Fire Pipeline Maintenance: Flush impurities,scale and residual foam from pipelines to ensure unobstructed water flow-critical for sprinkler system efficiency.

System Pressure Testing: Low-flow drainage (TEST gear) to verify pipeline pressure stability,wet alarm valve response sensitivity without emptying the entire system.

Winter Freeze Prevention: Full-flow drainage (DRAIN gear) of residual water in outdoor pipelines,hydrants or unheated areas to avoid pipe bursting from freezing.

Emergency Drainage: Rapid water release during fire system repairs (e.g., valve replacement,pipe leakage) to reduce maintenance downtime.

 

5. Frequently Asked Questions (FAQ)

 

How is it different from previous water guns/nozzles?It's a maintenance valve (not a fire suppression tool) - water guns/nozzles are for extinguishing fires, while this product is for fire system drainage,testing and freeze prevention-core functions and usage scenarios are completely unrelated.

Why use brass instead of other materials?Brass has natural corrosion resistance to water/foam mixtures, avoiding rust jamming (common in iron valves) and scale buildup (problematic for plastic valves). It also withstands temperature extremes (-20℃~+60℃), suitable for indoor/outdoor fire systems.

What's the meaning of the K5.6 flow coefficient?K5.6 refers to the flow efficiency of the valve-ensures fast drainage (≥5L/min for DN15) during full-flow mode, and stable low flow during pressure testing, balancing efficiency and precision.

How to maintain this drain valve?

After use, switch back to OFF gear to keep the valve sealed.

Every 6 months: Check the gear switch flexibility and seal for leakage (replace the rubber seal if needed).

Store in a ventilated dry place when not installed-avoid contact with acids/alkalis to prevent brass corrosion.
