Pressure Regulating Valves Type 582/586 Product description Operating Instructions Pressure reducing valves type 582 and the pressure retaining valves type 586 are intended to be operated with pure, non-abrasive liquid media. The product and all of its components are intended to be used within the permitted pressure and temperature limits and in accordance with their chemical resistance. Pressure reducing valve type 582 The pressure reducing valves type 582 are intended to reduce the system pressure, after installation into a piping system, and to keep it constant at the specified value to the...

Operating Instructions Pressure Regulating Valves Type 582/586 Cartridge Diaphragm, O-rings, diaphragm washer, inner body and piston constitute the cartridge. Function 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...

Pressure Regulating Valves Type 582/586 Operating Instructions Diaphragm, O-rings, diaphragm washer, inner body and piston constitute the cartridge. The desired pressure in the valve inlet pipe is set by the adjustable spring force. If the inlet pressure rises above the set value, e.g. due to an over capacity of the pump, the valve piston is lifted against the spring force. Consequently, the valve opens, and there is a reduction of pressure into the outlet. If the pressure decreases in the valve inlet pipe, the spring resistance pushes the piston down in the direction of the valve seat and closes,...
