Here's what Martin Nowak had to say: I found the ambulance for Tri-State at a local shop. It’s a 2013 Ford F-450 chassis with a 2014 Wheeled Coach body. It was originally a demo unit before being purchased by the district. From Fire Service, Inc.: Congratulations once again to Chief Mancione and the Tri-State Fire Protection District for placing an order for two brand-new Wheeled Coach Type 1 ambulances! This follows the recent purchase of a demo model, and we’re thrilled to be expanding our partnership with them. Thank you for your continued trust in our products and services!

Martin Nowak photo Martin Nowak photo This is a great example of how fire departments often look for quality, reliable vehicles that meet their specific needs. The fact that they chose to purchase a demo model first shows they were confident in the product, and now they're taking it a step further by ordering two more units. It's always exciting to see such strong support from local agencies, and we're proud to be part of this growing relationship with Tri-State Fire Protection District.

Tri-State FPD buys new ambulances
The role of the valve is specifically responsible for the input of air into the engine and exhaust the exhaust gas after combustion. From the engine structure, it is divided into Intake Valve and exhaust valve.
The role of the intake valve is to draw air into the engine and mix it with the fuel to burn; The function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate heat.
The valve is composed of a valve head and a rod. The valve head temperature is very high (intake valve 570~670K, exhaust valve 1050~1200K), but also withstand the pressure of the gas, the valve spring force and the transmission component inertia force, its lubrication, cooling conditions are poor, requiring the valve must have a certain strength, stiffness, heat and wear resistance.
The intake valve is generally made of alloy steel (chromium steel, nickel-chromium steel), and the exhaust valve is made of heat-resistant alloy (silicon chromium steel).
Sometimes in order to save heat resistant alloy, the exhaust valve head is made of heat resistant alloy, and the rod is made of chromium steel, and then the two are welded together.
