Description

The key components of all Firefighting Systems are Firefighting valves like Isolation Gate valves, Check valves Alarm check valves, Zone control valves, Pre-action valves, Pressure reducing valves, etc. A fire event can cause untold damage to property. But sometimes, efforts to put out the fire can be just as catastrophic. Water can do as much damage to electronic equipment, paper, and other moisture-sensitive items as the fire itself. Dutco Tennant LLC offers the most comprehensive range of valves and firefighting systems which are smartly designed keeping in mind about your safety. Our range of firefighting products is certified and is advanced. With the experience of over four decades, be assured to get complete resistance from fire and save yourself and your business from sudden fire breakouts.

Pressure Reducing Valve

The most practical components for maintaining secondary, lower pressure in a hydraulic system are pressure-reducing valves. These valves are normally open, 2-way valves that close when subjected to sufficient downstream pressure. Our Pressure Reducing Valve, which is UL labeled and listed, is ideal for automatically reduces a higher inlet pressure to a steady lower discharge pressure, regardless of fluctuations in flow or inlet pressure. The valves are based on the 106-PG control valves and are available in a complete range of sizes from 2 in / 50 mm to 8 in / 200 mm. In typical pressure reducing applications, the globe style 106-PR-10159 is often the preferred valve style.

Pressure Relief Valve

Most of the fluid power systems are designed to operate within a preset pressure range. This range is a function of forces the actuators in the system must generate to do the work. Without controlling or limiting these forces, the fluid power components could be damaged. Relief valves avoid this hazard. They are safeguards which limit maximum pressure in a system by diverting excess oil when pressures get too high. The pressure relief valve, which is UL / FM labeled and listed, automatically relieves excess pressure in the fire protection system to discharge. The RPS series valves will also automatically modulate to relieve excess pump capacity during pump start-up and shut down, allowing the pump to operate without causing surges. These relief valves are based on the 106-PG or A106-PG main valves and come in a complete range of sizes from 2 1/2 in / 65 mm to 8 in / 200 mm. In a typical pressure relief application, the angle style A106-RPS-8700 is often the preferred selection.
