UL LISTED HALLS
UL listed fire fighting valves are critical safety devices (like gate, butterfly, deluge valves) certified by Underwriters Laboratories (UL) to meet rigorous performance, durability, and safety standards for controlling water flow in fire suppression systems, ensuring they work reliably in emergencies
GATE VALVE
- INTRODUCTION
- FEATURES
In the field of fire fighting systems, gate valve play a crucial role in controlling the flow of water and extinguishing fires effectively. Especially designed specifically for firefighting applications. Gate valves are a vital component that ensures the safety of life and property during emergency situations.
It operates by opening and closing via a gate type valve disc, and raising the gate allows water to flow through the valve while lowering the gate cuts off the water flowing through the valve.

BUTTERFLY VALVE
- INTRODUCTION
- FEATURES
A butterfly valve for fire protection starts, stops, or throttles the flow of water via the rotation of an internal disc. When the disc is turned parallel to the flow, water can pass through freely. Rotate the disc 90 degrees, and the movement of water into the system piping stops.Lug butterfly valve (Gear actuator & tamper switch) is light weight valve with signal gearbox, and lug is positioned on the valve flanges for bolt connection. The valve is fully open or closed when the disc is rotated a quarter turn.

- Connection: Flanged as EN 1092-2, etc.
- Contact rating: 16A at 125/250VAC; 0.5A at 250VDC; 10A at 36VDC
- Temperature: 0°C to 80°C
- W. pressure: PN 16
- Surface: FBE coating as AWWA C550
FIRE CHECK VALVE VALVE
- INTRODUCTION
- FEATURES
A "FIRE CHECK valve" typically refers tocheck valve in a fire protection system that allows water to flow only one way (from source to sprinklers) to prevent backflow and maintain pressure, like an alarm check valve for wet systems that also triggers alarms. It can also mean a specialized thermal shut-off valve (FireChek) that stops air supply to pneumatic actuators during a fire, protecting equipment. Both types ensure system integrity and safety during emergencies.Flanged swing check valve is swing type check valve (non-return valve) with flanged connection.
- Certificate: UL Listed / FM Approved
- Standard: EN 1074-3
- Connection: Flanged as EN 1092-2
- Temperature: 0°C to 80°C
- W. pressure: PN 16 / PN 25
- Surface: FBE coating as AWWA C550
STRAINER VALVE
- INTRODUCTION
- FEATURES
A FIRE STRAINER valve (or simply Fire Strainer) is a crucial device in fire protection systems that filters out rust, dirt, and debris from water flow, preventing damage to sensitive components like pumps, sprinklers, and nozzles, ensuring clean, unobstructed water delivery for effective firefighting, often using Y-type or Basket types with cleanable screens for maintenance. It is used for remove foreign matter from flowing fluids by wire mesh filter element, so to protect pump, meter, valves, and other mechanical equipment.
- Certificate: UL Listed / FM Approved
- Standard: EN 1074-3
- Connection: Flanged as EN 1092-2
- Temperature: 0°C to 80°C
- W. pressure: PN 16 / PN 25
- Surface: FBE coating as AWWA C550
PRESSURE REDUCING VALVE
- INTRODUCTION
- FEATURES
A Fire Pressure Valve, typically a Pressure Relief Valve (PRV) or Pressure Reducing Valve (PRV), is a critical safety device in fire protection systems that automatically controls and limits water pressure, preventing dangerous overpressure from pump surges or variable speed drivers, protecting system components and ensuring safe operation by releasing excess water to a sump or atmosphere when preset limits are exceeded, then closing tightly.
- Certificate: UL Listed / FM Approved

STAINLESS STELL VALVE
- INTRODUCTION
- FEATURES
A Fire Stainless Steel Valve is a robust valve, often a ball valve, made from durable stainless steel (like 304/316) designed to withstand high heat and pressure, acting as a critical safety device in HVAC, industrial piping, and fire suppression systems to control flow and prevent fire/smoke spread, featuring fire-safe certifications (API 607) and enhanced sealing for emergencies.
