Self-Acting Pressure <strong>Control</strong> Pressure Reducing Valve 5801 ∅ d G 1/ 8" Strainer Pressure-reducing valve 5801 G 3/ 8" L ∅ A l Water-seal pot Pessure-reducing valve min. 1m min. 10 x D Schematic installation diagram H h 1 17.2 x 2.6 Water-seal pot Sensing line 8 x 1.0 mm Sensing line connection Application Type 5801 Pressure-reducing valve for use with steam and other fluids. In all energy and process systems. Design The pressure-reducing valve is a balanced single-seat proportional controller operating without auxiliary energy. The pressure-reducing valve consists of a body with internals, bellows, spring, handwheel and actuator. For steam and liquids at temperatures above 100 °C a water-seal pot is required to protect the actuator diaphragm.
