Pressure Reducing Valve 582

Durable, dependable and simple to use, the Type 582 Pressure Reducing Valve’s design reduces the pressure on the outlet of the valve. It is used to reduce higher pressure from main lines or to protect sensitive devices from being damaged by too much pressure.

Functions of pressure reducing valve

On the side of the valve outlet, the pressure acts via the diaphragm on the adjustable spring. A balance of forces is established via the preloaded spring, which is set with the adjusting screw at the valve. If the outlet pressure increases above the specified value, the piston is lifted against the spring force. The valve closes, and the outlet pressure is reduced. If the outlet pressure decreases below the value, the piston is pushed down by the spring resistance. The valve begins to open, until the balance is reached again.
Independent of an increasing or decreasing inlet pressure, the outlet pressure remains constant to the greatest possible extent, because it is not directly related to the inlet pressure.

Fluidos

Technically pure neutral and aggressive liquids, if the selected valve materials are resistant to the operating temperature according to the Divatec resistance list.
