Butterfly Valve | 567

Butterfly Valve - Overview

The butterfly valve has all-plastic housing which combines quality and durability. Through the use of fibreglass reinforced polypropylene, the valve's weight is greatly reduced. This simplifies not only the installation of the valve but also saves on the storage cost. The valve can be used reliably in highly corrosive applications and is excellent for use with aggressive media. The system allows the exchange of individual system components at any time - quickly and easily, without much effort. The maximum nominal pressure is 10 bar on both sides at 20 °C. A further benefit of this is the long life span since the valve is less exposed to wear and tear. Suitable for most applications in industrial water treatment, the chemical process industry, chemical trade, galvanization and in power plants. The valve is modular in design, allowing individual system parts to be exchanged at any time.

Butterfly Valve - Features
- High corrosion resistance
- Low wear and tear: up to 50 % lower operation torque than centric valves

Pressure Reducing Valve | 582

Pressure Reducing Valve - Overview

The pressure-reducing valve reduces the outlet pressure to a specified value. Pressure-reducing valves are often used to protect downstream devices against overpressure. The downstream pressure works against the spring resistance and raises the diaphragm until equilibrium is reached. The desired outlet pressure is regulated using the spring pre-tensioning. The inlet pressure is not directly related to the outlet pressure. The pressure at the outlet thus remains constant despite fluctuations at the inlet. The diaphragm is not influenced by pressure peaks, meaning sensitive measuring devices can be protected downstream. The set pressure can be increased by turning the spindle at the top of the valve in a clockwise direction. Turning it counterclockwise reduces the set pressure. Inward-pointing arrows assist in visualising the direction of the flow and the pressure setting, making handling easier. Applications include water treatment, chemical processing, the semiconductor industry and the solar industry. Suitable for neutral and aggressive media with a small amount of particles or solids.

Pressure Reducing Valve - Features
- Constant and stable control behaviour
- Leak-resistant in the event of temperature fluctuations
- Low maintenance
- Pressure setting possible even during operation
