Product Overview
Description
| FRNG | Spring loaded regulator with adjustable rating spring and predetermined counter spring. Equipped with regulator output pressure internal connection, prepared for external pulse and fan pressure connections. Suitable for variable control of the regulator output pressure by means of pneumatic commands. | |
| Nominal diameter | DN 40 50 65 80 100 125 150 | |
| Pipe thread according to S07/1 | Rp 3/8 1/2 3/4 1 11/2 2 | |
| Flanges | Connection flange according to DIN EN 1092-1 (PN 16) | |
| Max. working pressure | Up to 500 mbar (50 kPa) | |
| Pressure regulator | Pressure regulator according to EN88-1, class A, group 2, DIN3380RG10, EN12078 | |
| Input pressure range | Zero pressure regulator | 5 to 200 mbar (0,5-20 kPa) |
| Pressure proportional regulator | 5 to 200 mbar (0,5-20 kPa) | |
| Pressure regulator for compressed air control | Up to 500 mbar (50 kPa) | |
| Output pressure range | Zero pressure regulator | -3 to 5 mbar (-0,3 to 0,5 kPa) |
| Pressure proportional regulator | -10 to 150 mbar (-1 to 15 kPa) | |
| Compressed air-controlled regulators | up to 350 mbar (35 kPa) | |
| Material of the gas guiding section | Housing: aluminum, steel, non-ferrous metal free | |
| Seals and diaphragms: NBR | ||
| Ambient temperature | -15℃ to +70℃ | |
| Mounting position | -Regulator cover vertical to horizontal position:Rp3/8-DN100 | |
| -Regulator cover vertical position:DN125,DN150 | ||
| -Overhead regulator:Rp3/8-DN150 (zero pressure regulator) | ||
| Measuring and ignition gas connections | G1/4IS0228 on both sides of the inlet range | |
| Measuring opening | G1/8IS0228 in the bottom cover (optional DN125,DN150) | |
| The opening, which can be reclosed, can be opened to adjust the device-related values when starting up a device, e.g. a gas engine. | ||
| Bypass | Bypass prepared: Rp3/8-Rp2 on the right side of the housing | |
| Pulse connector | The outlet area is equipped with an internal pulse. | |
| Outer pulse connector prepared on the housing: Rp3/8 to Rp1,on the left side, G1/8; on the | ||
| both sides from Rp11/2,DN40G1/4; internal pulse can be switched off | ||
| Ventilation tube/blower pressure fitting | Without the need to install a ventilator, the existing fitting can be used as a pressure fitting for the command variable (blower pressure). | |
| Fittings: G1/4 to Rp1;from Rp11/2,DN40:G1/2 | ||
| Command variable fan pressure | Pressure ratio of approx. 1:1 for isobaric applications and air-to-air ratio regulation, compressed air controlled operation: P. large = 150mbar (15 kPa) | |
| Spring selection | The output pressure depends on the installed regulator spring, the spring force of the counter spring and the level of fan pressure present. The regulator is fitted with a brown spring 1 as standard. | |
| By changing the regulator spring, a larger positive zero offset (offset) of the output pressure can be realized. |
