Weflo Pressure Switch Fire Protect Fig. WPS
Precision Detection for Fire Safety Systems in Critical Industrial Applications
Introduction: Why Valves and Detection Systems Are Crucial in Industrial Safety
In industrial operations where fluid and gas systems are central to daily processes, ensuring proper flow control is essential. However, in systems designed for fire protection, valves alone are not enough. These networks also depend heavily on detection and actuation devices such as pressure switches to initiate timely and effective response during emergencies.
Modern fire suppression systems—especially in facilities handling hazardous materials, high-voltage equipment, or critical operations—require not only robust control valves, check valves, gate valves, or ball valves, but also intelligent signaling devices that monitor pressure changes and trigger alarms or system actions when necessary.
This is where the Weflo Pressure Switch Fire Protect Fig. WPS plays a pivotal role. Built with durability and precision in mind, the WPS Series from Weflo is UL/FM listed and trusted for a wide range of fire protection systems. It is engineered for high reliability, environmental resilience, and continuous monitoring in even the harshest industrial settings.
Product Overview: Weflo Pressure Switch Fire Protect Fig. WPS
The Weflo WPS Series Pressure Switch is designed to detect a change in pressure within fire suppression systems and to send a signal to fire alarm panels or other connected devices. This switch can be used in wet, dry, deluge, or pre-action sprinkler systems, making it one of the most versatile options on the market for pressure-based fire system activation and monitoring.
This pressure switch is rated for both indoor and outdoor installations, and with an operational temperature range from -40°C to 60°C, it performs reliably in harsh climates — from frozen outdoor installations to warm mechanical rooms.

Product Features and Benefits
1. UL / FM Certified for Fire Protection Use
Certified by the world’s most trusted fire protection agencies, UL (Underwriters Laboratories) and FM (Factory Mutual), the Weflo WPS Series meets stringent quality and safety standards for use in life-critical applications. It is ideal for industrial facilities, commercial buildings, and critical infrastructure requiring fail-safe components.
2. Wide Compatibility Across Valve Systems
Whether your fire protection system uses gate valves, check valves, ball valves, or automated control valves, the WPS pressure switch integrates seamlessly. It monitors pressure behavior across the valve network and alerts central systems when anomalies arise, triggering response mechanisms and alarms.
3. Temperature Resilience: Operates in Extreme Environments
With an operating range from -40°C to 60°C, the WPS switch is ideal for outdoor applications such as oil refineries, offshore platforms, and chemical plants where fire protection equipment is exposed to temperature extremes.
4. Continuous Duty Cycle
Engineered to function 24/7 under continuous pressure conditions, the WPS Series is 100% duty rated, ensuring round-the-clock reliability with minimal maintenance.
5. Clean Air Medium
Designed to work with clean air, this device is suitable for pneumatic and pressurized systems where purity is essential — such as in pharmaceutical facilities, data centers, and electronics manufacturing.
Applications Across Industrial Sectors
The Weflo WPS Pressure Switch is applicable in virtually any industrial or commercial fire suppression setup. Below are some common use cases:
1. Power Generation Facilities
Power plants rely on deluge or pre-action fire protection systems that require precise pressure monitoring. A sudden drop in water line pressure can trigger fire suppression; the Weflo WPS ensures this is detected immediately and reliably.
2. Oil & Gas Installations
In upstream and downstream sectors, fire risk is exceptionally high. The WPS switch is often installed alongside check valves and control valves to ensure pressure behavior is monitored around storage tanks, pump rooms, and flare systems.
3. Warehousing and Logistics Hubs
Warehouses often use pre-action systems to avoid accidental discharge in areas storing sensitive goods. The pressure switch provides early warnings for leaks or mechanical failure.
4. Chemical and Petrochemical Plants
Complex piping systems with valves controlling flammable media rely on pressure switches like WPS to monitor sprinkler line conditions. In case of pipe rupture or heat-triggered valve release, the pressure drop is instantly communicated.
5. Commercial High-Rise Buildings
High-rise sprinkler risers can experience fluctuating pressure due to building height and pump behavior. The WPS helps monitor and stabilize such systems, ensuring fire readiness.
