Product catalog summary

General Overview
Differential pressure regulators are designed to stabilize vacuum systems, primarily used in gas chlorine installations. They can also be adapted for other gases with minimal alterations. These regulators are constructed from high-quality, resistant materials such as tantalum alloys for springs, special ABS plastic or rigid massive PVC for housing, and quality materials like ECTFE foil, FPM/FKM, PTFE Teflon, and PVDF for diaphragms, O-rings, gaskets, and washers. This ensures reliable operation under high mechanical and temperature loads.

Operation Principle
The return pressure acts on the underside of the diaphragm. The diaphragm and spring work together to respond to system changes and maintain a constant pressure with minimal vacuum loss. As system pressure increases, the diaphragm moves the valve to maintain controlled circuit pressure.

Technical Specifications
The document lists various models of differential pressure regulators (DP1, DP2, DP3) with specific dosing ranges and gas types they are compatible with, including chlorine (Cl2), carbon dioxide (CO2), sulfur dioxide (SO2), and ammonia (NH3). The dosing range varies depending on the model and is specified in kg/h.

Ordering Information
Order codes are provided based on the model, gas type, and dosing range. The appropriate number from the technical data table is included in the ordering code to specify the desired configuration.
