Hose valves are recommended for installation in interior and exterior locations not subject to freezing. These valves have heavy rough brass body with machined brass vandal-resistant lock shield bonnet and are furnished with a removable wheel handle. Valves close with the pressure and feature a replaceable cartridge, which contains all wearing parts including the seat.

Hydrant valves permit the first-in pumper to lay the large diameter line directly from hydrant to fire and start pumping water. If more pressure is required to boost the pressure at the hydrant to take full advantage of available water, another pumper can connect to the hydrant valve and start pumping with no interruption in flow.

Hydraulic Dashpot is charged with shock-absorbing fluid. The piston is provided with ports and valves. This is mounted on one end of a piston rod and divides the cylinder into two chambers. The dashpot also comprises an adjustable bypass accommodated inside the piston rod or inside an extension on rod travels in and out of the cylinder. It can be provided with a bore. The cross-section of the bypass during the compression phase can be established independent of its cross-section during the suction phase. Each plunger operates in conjunction with a radial inlet or outlet. The control rod with a rotary connection is accommodated inside the bore that extends through the piston rod and can be alternately connected to the plunger connections.

Hydrogen leak detector is a unique instrument for industrial leak detection and tightness control. This is sensitive and can be used to find leaks as small as 5 x 10-7 mbar x l/s, comparable to leaks 1000 times smaller than detectable with a traditional soupy water or bubble tests. The inherent characteristics of Hydrogen enable fast, precise and safe leak location and qualification. Hydrogen leak detection is done with a safe 5% hydrogen in 95% nitrogen gas mix. Because hydrogen is quickly transported to the leaks and dissipates much faster than other gases it allows for much quicker testing and re-testing than other gases.

Indicator post is used in fire protection systems and performs two functions. First it provides a means to operate a buried or otherwise inaccessible valve and second it readily and clearly indicates whether the valve is open or shut. Adjustable type indicator post design has a built-in 18″ adjustment span.

Indoor speaker unit provides reliable indoor alarm tone notification and emergency voice instructions with up to 400W of continuous audio output power. Its audio amplifier greatly reduces component count and wiring, which insures high system reliability. Its automatic gain insures constant output volume level during live voice announcements.

Industrial woven fire hose is a single jacket, polyester industrial fire hose with an ozone-resistant EPDM rubber lining. The spun polyester yarn jacket offers superior strength and wear characteristics. It is designed for interior or exterior fire protection where lighter weight rack and reel type hoses are not adequate.

Intumescent fire barrier is heavy-bodied, single-part latex. It is designed for use on construction materials such as oriented strand board, structural insulated panels, framing lumber, plywood, trusses, drywall and doors. It is also be used on aluminum and steel sheets, round and box steel columns.

Large Dry Chemical Systems combine the flexibility of a hand portable fire extinguisher with the fire-killing power. This is designed for protection of extra hazardous areas where large fires must be extinguished. This features greater agent capacity, longer discharge times, and higher flow rates than portable extinguishers. It includes nitrogen cylinder to provide for pressurization of the tank and fluidization of the dry chemical, storage tank to hold a quantity of dry chemical extinguishing agent, hose line(s) to deliver the agent from the storage tank to the nozzle assembly and nozzle assembly to control and direct the flow of dry chemical to the fire.
