Self-Actuating Pressure Reducing Regulators

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.
