TS 12259 Valves - Used in PN 16 Fire Hoses (For Land Fire Brigade)

Valves used in fire hoses are valves that mechanically open, close or partially block the water flow from the fire hydrant or large pump inlet. These valves provide a wide variety of hydrant connections as needed. In the TS 12259 standard, the requirements for the valves used in fire hoses of the land fire brigade and up to a nominal pressure of up to 16 bar are explained and a test method is defined.

Generally, a hose or hydrant valve is used to control water flow in a fire scene or industrial setting. Different applications require different fire hose valves, including deluge and dry riser valve types. Mainly other common types of hose valve include:

• Angle valves: Used with rack hose assemblies and automatically drain and vent.
• Ball valves: Used in pump discharge, gated networks and fire pump piping systems.
• Gate valves: Used to control flow from a hydrant or flow in large pump inlets.

In general, these valves are made of light alloys and feature a stainless steel ball shutoff. Fire hydrant valves, on the other hand, have self-locking handles.

The two standards that were taken into consideration in the preparation of the mentioned standard and designed by the German Standardization Institute (DIN) are:

• DIN 14461-3 Fire-fighting distribution valve installations - Part 3: Fire hose valves for nominal pressure PN 16
• DIN 14461-5 Fire-fighting distribution valve installations - Part 5: PN 16 tap in connection with fire-fighting pipes

Fire hydrant valves are an important source of water, which is crucial for fighting fires. The fire hydrant valve is an essential part of the hose system, providing full control over the fire suppression system and acting as a manual stop valve.

Among the numerous tests, measurements, analyses, and evaluations our organization provides for businesses in various sectors, we also offer testing services for valves used in PN 16 fire hoses (for land firefighting) in accordance with the TS 12259 standard, thanks to our trained and expert staff and advanced technological equipment.
