Functions & Features - DN range15 - 250 mm- kvs range0.4 - 400 m3/h- PN range10, 16, 25, 40 bar- Max temp. range120 - 150º C*- Connection typethread / flange- Settingvariable / fixedDifferential pressure controllers’ purpose:is to maintain a constant differential pressure across the substation / control valve connected to a heating or district heating system. The controllers close on rising differential pressure.The function of differential pressure controllers:the high up-stream pressure is led to the lower part (high pressure connection) of the diaphragm. Through a channel in the controller, the medium pressure is led from the valve to the upper side of the diaphragm. The spring power now affects the upper part (low pressure connection) of the diaphragm, thus determining the effective differential pressure. * Products for temperatures up to 200 or 350° C require special accessories to function correctly - see data sheets
