Pressure reducer V 182 . V82

Product catalog summary

Overview
The document provides technical specifications and details for the Pressure Reducer models V 182 and V 82, which are designed to reduce system pressure to a defined value using differential pressure. These models are suitable for various applications and are made from highly resistant plastics.

Specifications
- Models: V 182, V 82
- Size Range: DN10 to DN100
- Materials: PVC-U, PP, PVDF
- Operating Temperature: 0 to +60°C for PVC-U, 0 to +80°C for PP, -20 to +100°C for PVDF
- Diaphragm Material: EPDM
- Gasket Material: EPDM, PTFE overlayed FKM

Functionality
The pressure reducer operates by balancing the pressure exerted on the diaphragm surface with the set spring force. It maintains constant operating pressure by opening or closing the valve as needed.

Special Features
- Hermetically sealed setup mechanism
- Good control properties due to optimized piston, pressure spring, and control surface
- No auxiliary energy required
- Largely maintenance-free and can be installed in any position
- Diaphragm-protected pressure gauge

Dimensions
The document provides detailed dimensions for various sizes and configurations, including socket fusion, butt fusion, and IR fusion.

Technical Data
Includes part numbers for different configurations and materials, such as PVC/EPDM, PVC/FPM, PP/EPDM, PP/FPM, and PVDF/FPM.

Components
The pressure reducer consists of several components, including the valve body assembly, valve bonnet assembly, piston assembly, compression spring, and various O-rings and screws.

Characteristic Diagrams
Graphs illustrate the decrease in set outlet pressure from 0 to the maximum permissible flow rate, applicable to water at 20°C.

Spare Parts
Lists spare parts for setting units and gaskets, with part numbers for different materials and configurations.

The pressure reducer V 182/ V82 reduces the system pressure to a defined value. Utilizing the differential pressure, the pressure reducer sets itself to the set operating pressure. The outlet pressure is not directly related to the inlet pressure. The output pressure is exerted onto the diaphragm surface through a control bore and counteracts the set spring force. Once balance of pressure has been achieved, the valve closes and keeps the operating pressure constant by doing so. If the pressure decreases at the output side, then the set spring force is greater, and the valve opens until the balance...
