Page Title
| Humat Inc. is the creator and manufacturer of the Humat 4-way Hydrant Valve, used by innovative fire departments and fire training schools across the USA and around the world as the most efficient method to get the most water on the fire ground in the least amount of time. Valves are made of lightweight aluminum alloy for easy handling, heat treated for extra strength and hard coated to prevent corrosion and to increase surface strength. Incredibly durable and designed for ease-of-use, Humat valves provide an exceptional return-on-investment to fire departments regardless of size. |

Keep in mind that the Humat 4-way Hydrant Valve is the simplest-to-use and maintain appliance available today. These operating hints (PDF) and maintenance procedures (PDF) are to help those of you who must write your department's technical directives. Valve Deployment First engine drops pre-connected valve at the hydrant and stretches line to the fire. Valve is connected to the hydrant, smaller chamber is positioned up or down depending on location of fire and hydrant is opened. Second engine lays two lines from fire to hydrant, connects sleeve to valve to supply those lines through the pump. Line is connected from pump discharge valve to bring initial supply line up to pump pressure. |

A Humat model 100 4-Way Hydrant Valve, with a 4 1/2" NST Steamer connection and a 5" Storz attached to the small
chamber was used. One 20' section of 5" Snap-Tite hose with 5" Storz couplings was attached to the small chamber and to
the pump inlet. A pressure gauge was fitted to a 2 1/2" blind cap on the hydrant to determine residual hydrant pressure and
an Engine Panel Inlet Gauge was calibrated to read inlet pressure. The hydrant was on 20" main with static pressure of 115
PSI.
Un-boosted readings in hydrant mode were the only readings taken because the friction loss and turbulence went to a
negligible level when switched to pump mode, even with 2000 GPM flows. Water flows in a straight line through a Humat
Valve in pump mode.
