Differential pressure control valves for industrial, foodstuffs and pharmaceutical plants are fully relieved either piston or membrane control proportional valves, and spring loaded depending on the differential pressure range.
Example: (opens when differential pressure increases) |
Nominal pressures : PN 1.6 to PN 16 Connections : G 1/4 to G 2 ½ or DN 10 to DN 100 Process connections : normal commercial thread, screw, clamp or flange connections Materials : 1.4301, 1.4571, 1.4404, 1.4435, as well as elastomer and thermo-plastic element seals Primary pressure ranges P2 : 0.005 bars to max. 8 bars Flow mediums : gases, vapours and fluids |
Areas of application Differential pressure control valves: 1、Volume governor combined with a pressure transducer upstream to the valve. 2、 Flow governor combined with a pressure transducer located at another part of the system. 3、 Pressure controller for impulse reduction from another part of the system. |
