Choosing the Right Fire Protection Valves | BIMEX Guide
In any fire protection system, valves are essential control components that determine the system’s effectiveness and compliance with fire safety regulations. Choosing the right fire protection valve ensures not only reliability in emergencies but also long-term durability, maintenance efficiency, and code compliance. At BIMEX, we manufacture a comprehensive range of UL-listed and FM-approved valves that meet global standards for performance in industrial, commercial, and municipal fire safety applications.
Understanding Valve Functions in Fire Systems
Valves in fire protection systems serve various critical roles:
- Controlling water flow to specific zones
- Preventing backflow
- Providing visible open/close status for safety inspections
- Ensuring fast, reliable activation during emergencies
Each application calls for a specific valve type that aligns with system design and operational requirements.
Key Valve Types Offered by BIMEX
1. OS&Y Gate Valves (Outside Screw and Yoke)
- Feature a visible rising stem to show whether the valve is open or closed
- Ideal for above-ground installations with clear line-of-sight
- UL listed, FM approved, and compliant with AWWA and NFPA standards
- Used commonly in main fire lines and pump rooms
2. NRS Gate Valves (Non-Rising Stem)
- Perfect for underground installations where space is limited
- The stem does not protrude during operation, reducing the risk of damage
- Protected design allows long-term use in harsh environments
3. Post Indicator Valves (PIVs)
- Provide a clear visual indicator of valve position (open/closed)
- Often used outside buildings with sprinkler systems
- Installed vertically for easy field inspection
4. Butterfly Valves
- Compact and lightweight design
- Quarter-turn operation for rapid control
- Low-pressure drop and high flow efficiency
- Suitable for indoor and above-ground pipe installations
5. Check Valves
- Prevent reverse flow that can damage system integrity
- Available in swing, wafer, or grooved-end styles
- Integral to pump rooms and main supply lines
BIMEX Valve Standards & Certifications

How to Choose the Right Fire protection Valve
When selecting a valve, consider:
- Installation environment (above ground, buried, pump room)
- Required function (flow control, backflow prevention, inspection visibility)
- System pressure and size
- Compliance needs (local code or insurer requirements)
Our team at BIMEX provides technical consultations to help specify the ideal valve type and configuration for each unique project.
