Self-Actuating Pressure Reducing Regulators
Regulators are applied in heating systems, in industrial processes with cold and hot
water, steam, air and non- flammable gases. Using with other media subject to
consulting with manufacturer.
| Technical Table | |
| SNR1 | Used to control preset pressure in process installations connected to valve outlet. |
| SNR2 | For regulation of pressure after the valve with an intensifier. |
| SNR3 | Used to control preset pressure in process installations connected to valve inlet. |
| SNR5 | For control of pressure differences on the installation connected with the regulator in series. |
| SNR6 | For control of pressure differences with flow limitation on the installation connected with the regulator in series (installation on the return). |
| SNR7 | For control of pressure differences on the installation connected with the regulation parallel. |
| SNR8 | For flow regulation. |
