APPLICATION AND SCHEMATIC EXAMPLE GENERAL SPECIFICATIONS 1. DIFFERENTIAL PRESSURE CONTROL VALVES - FLOWCON PIM™-DP 1.1 Contractor shall install the differential pressure control valves where indicated in drawings. 1.2 Valve shall be a mechanically operated, differential pressure control device, which shall accurately control differential pressure over a sub-system independent of system pressure fluctuations. 1.3 Valve shall be able to function as a shut off valve. 1.4 Valve shall be serviceable by replacing/cleaning filter in the adjustment tube. 2. VALVE HOUSING 2.1 Housing shall consist of ductile iron ASTM A395 Grade 60-40-18, rated at no less than 2500 kPa (360 psi) static pressure and +120°C (+248°F). 2.2 Housing shall be permanently marked to show direction of flow. 2.3 Housing shall be for installation between flanges. 2.4 Dual pressure/temperature test plugs for verifying accuracy of performance shall be standard on all valve sizes. 3. PRESSURE REGULATION UNIT 3.1 Regulation unit shall consist of stainless steel. 3.2 Regulation diaphragm must be an EPDM in-line rolling diaphragm. Flat diaphragm or external disc regu- lation are not accepted. 3.3 Regulation unit shall be externally adjustable with the valve in-line and the system in operation. 3.4 Regulation unit shall allow differential pressure adjustment within 25-170 kPaD (4-25 psid). 3.5 Regulation unit must protect the system against noise and must have a clearly defined differential pres- sure range within a flow range of 2270-32900 l/hr (9.99-145 GPM) for DN65/80 (2 1/2”-3”), 13600-82900 l/hr (59.9-365 GPM) for DN100 (4”) and 18200-119000 l/hr (80.1-524 GPM) for DN125/150 (5-6”).
