SS. Proportional Pressure Reducing Valve

Ensuring Practical, Safe Working Water Pressures Municipal and private water supply companies use pumps and pumping stations to boost water supply pressures in supply mains to be able to supply water for fire fighting, high rise buildings to overcome loss of pressure as the elevation increases, and to maintain water supply in water towers and supply tanks. Pressure in water supply mains can exceed 200psi. Most plumbing codes require water pressure reducing valves on domestic systems where the municipal water main's pressure exceeds 80psi. Higher pressures could rupture pipes, damage fixtures,and injure the people using them.
