Viking Fire Protection Sprinklers and Valve Systems

Viking automatic fire sprinklers, ESFR warehouse heads, EasyPac alarm check valve stations, deluge valves, and foam systems: engineering specification for industrial facilities.

Standard response and quick response fire sprinkler heads

Viking standard coverage fire sprinklers are engineered for wet and dry automatic fire suppression installations in commercial and industrial facilities. The calibrated thermal bulb swiftly activates under elevated ambient heat, releasing uniform firefighting discharge.

Models VK100, VK102, VK300, and VK302 with standard threaded connection fittings
Pendent, upright, and horizontal sidewall body profiles matching room architectures
Heat-sensitive fluid bulbs with precise activation ratings between 57 and 182 Celsius
Corrosion-resistant brass and chrome exterior finishes suited for humid atmospheres

Early Suppression Fast Response storage ceiling sprinklers

Viking high-output ESFR storage sprinklers protect high-piled distribution logistics warehouses with ceiling heights reaching fourteen meters. Heavy water droplets penetrate intense upward thermal plumes, suppressing the fire origin directly at floor level racks.

Models VK500, VK503, and VK510 delivering high discharge ratings from K202 to K363
Fast-acting fusible solder link mechanism triggering rapid water discharge on heat
Minimizes the requirement for intermediate in-rack sprinkler pipe line installations
Engineered deflector plate generating a dense hemispherical droplet protective zone

Wet pipe riser check assemblies and alarm control valves

Viking EasyPac alarm check valve stations divide main inlet headers and distribution loops within automatic sprinkler systems. Upon downstream pressure drop, the internal clapper opens, driving a hydraulic alarm gong and signalling building monitoring consoles.

Compact pre-trimmed alarm riser manifold equipped with dual precision system gauges
Retard chamber preventing erroneous alarm events from fluctuating intake surge waves
Flanged and grooved connection dimensions spanning DN50 to DN200 rated at 16 bar
Integrated pressure switch interfaces transmitting warning signals to main panels

Deluge and preaction flow control valve stations

Viking Torrent and FSX-A deluge valves safeguard high-hazard industrial units via water spray and foam installations. The fast-acting diaphragm design delivers immediate flow through open nozzles across the hazard zone upon electronic fire detector confirmation.

Durable diaphragm configuration without internal mechanical hinges ensures uptime
Pneumatic, hydraulic, and solenoid electric pilot activation trim configurations
Operating pressure rated to 1.6 MPa for storage tank farms and transformer bays
Modular stainless steel and galvanized trim piping incorporating manual drain ports

Concealed ceiling and dry barrel sprinkler solutions

Viking VK426 concealed sprinklers mount flush with cleanroom and commercial ceilings, hidden behind flat decorative plates. Dry barrel sprinklers isolate water from freezing conditions in unheated logistics distribution bays and refrigerated food cold rooms.

Smooth decorative cover plates available in varied architectural paint finishes
Extended dry barrel barrels preventing freeze damage in sub-zero freezer spaces
Recessed profile prevents mechanical impact during warehouse material handling
Threaded vertical adjustment simplifies alignment with finished ceiling surfaces

Industrial foam firefighting proportioners and hardware

Viking foam hardware combining ILBP inline balanced proportioners and SFFF synthetic concentrates protects flammable hydrocarbon storage. The assemblies maintain accurate foam admixture percentages across fluctuating pipeline water flows and delivery pressures.

ILBP inline proportioners feeding multiple hazard risers from one concentrate line
Low and high expansion foam generators filling aircraft hangars and bulk bays
Fluorine-free synthetic foam concentrates reducing ecological cleanup impacts
Diaphragm bladder tank vessels finished with robust corrosion-resistant liners

Hydraulic calculation and design of Viking standard and quick response sprinklers

Viking standard response and quick response automatic fire sprinklers featuring Job Thermo-Bulb heat-sensitive elements protect administrative, mercantile, and light manufacturing facilities.

The sprinkler functions through the calibrated destruction of the fluid-filled glass bulb upon reaching ambient activation thresholds spanning 57 to 182 degrees Celsius. This releases the internal Teflon-coated seal cap assembly, directing high-pressure water onto the deflector plate.

Models VK100, VK102, VK300, and VK302 with 1/2-inch and 3/4-inch threaded inlet fittings ensure balanced water density across target floor envelopes with minimal hydraulic friction, allowing fire protection engineers to optimize distribution header pipe sizing.

Viking Early Suppression Fast Response (ESFR) storage ceiling sprinkler engineering

To safeguard high-piled pallet storage and logistics fulfillment centers without intermediate shelf pipework, The Viking Corporation developed ceiling-mounted Early Suppression Fast Response (ESFR) sprinklers.

Models across series VK500, VK503, and VK510 provide discharge ratings spanning K202 to K363 utilizing fast-acting fusible link solder mechanisms.

Upon thermal detection, the deflector discharges high-momentum water droplets capable of penetrating intense upward combustion plumes, delivering direct cooling at storage floor levels.

This rapid intervention suppresses high-hazard fires before neighboring storage bays ignite, protecting warehouses with clear heights up to fourteen meters.

Viking EasyPac alarm check valve stations and wet pipe riser manifolds

Viking EasyPac wet pipe alarm valve stations function as integrated riser manifolds combining alarm check valves, pressure gauges, retard chambers, and electronic flow switches.

Stationed at the primary supply intake of the building sprinkler network, the assembly isolates the main water distribution lines. Downstream sprinkler activation generates a pressure gradient that lifts the hinged valve flapper, routing water through internal alarm ports into the retard chamber.

The retard chamber dampens pressure fluctuations from external water mains, while continuous flow activates hydraulic water gongs and closes electrical contacts for fire panel notifications.

Deluge and preaction flow control valve stations for high-hazard installations

In hazardous industrial environments such as flammable fuel storage parks, electrical power transformers, and chemical processing complexes, Viking Torrent and FSX-A deluge valves provide rapid flood protection rated to 1.6 MPa.

The internal shutoff element consists of a reinforced elastomeric diaphragm held shut by fluid pressure in the upper control chamber without internal mechanical latches.

Pressure release via pilot solenoid valves, pneumatic sensor lines, or manual emergency stations allows instantaneous diaphragm opening. This delivers immediate water spray or foam solution through all open nozzles positioned across the hazard envelope.

Concealed ceiling sprinklers and dry barrel configurations for extreme climates

In pharmaceutical cleanrooms, corporate lobbies, and retail environments, visible sprinkler fittings compromise interior aesthetics. Viking VK426 and Mirage concealed sprinklers mount flush with finished ceiling panels behind decorative cover plates held by low-temperature solder.

Upon reaching actuation temperatures, the cover plate detaches, exposing the drop-down deflector.

For sub-zero industrial settings including unheated loading docks and refrigerated logistics freezers, Viking manufactures dry barrel sprinklers with sealed dry extensions, preventing water freezing behind the ceiling plane prior to sprinkler actuation.

Inline Balanced Pressure Proportioners (ILBP) and industrial foam hardware

To extinguish flammable hydrocarbon and chemical liquid hazards, Viking manufactures foam suppression equipment including Inline Balanced Pressure Proportioners (ILBP) and foam generators.

ILBP proportioners inject synthetic fluorine-free foam (SFFF) concentrates into water pipelines with high precision under shifting line pressures, maintaining target admixture percentages without chemical over-consumption.

Elastomeric bladder tanks isolate liquid foam concentrate from the steel tank walls, preventing fluid oxidation and ensuring dependable deployment throughout critical industrial emergencies.
