Armaş “DIF” model differential pressure sustaining valves keep differential pressure between two points at a fixed value regardless of variable flow rate and upstream pressure. The determined upstream pressure can be easily adjusted by a pilot valve. The valve controls booster pumps drainage, heating and cooling systems, bypass lines, filters and similar systems.
The valve will be diaphragm actuated disc closing automatic hydraulic control valve which works with line pressure. Double-chamber diaphragm actuator provides quicker and non-impact opening/ closing thanks to disc-closing valve design and prevents blockage by showing less sensitivity against solid substances within fluid.
Valve size same as main line or one size smaller. Maximum flow speed for continuous operation 5.5 m/sec (18 ft/sec)
