It is known in the market like no other: the bob综合体育官网下载 BETA® Gate Valve, which has been synonymous for resiliant-seated gate valves worldwide since 1968. 57 years after its launch, the BETA 500, the youngest member of the series, will be launched on the market in 2025, setting standards for the future. This innovative valve combines state-of-the-art technology and maximum precision and offers the most reliable shut-off function on the market. Combined with environmentally friendly production and proven quality, the BETA 500 meets the demanding requirements of the 21st century to a particularly high degree.

Control valves made by bob综合体育官网下载 are real allrounders: Sophisticated engineering makes these valves control professionals designed to the specific requirements of each customer. In this context, precision in the control of enormous amounts of water while almost completely preventing cavitation wherever possible always has first priority, as the control of pressure and flow in water pipeline networks and the regulation of the level in water tanks range among the fundamental disciplines in water management. Cavitation, a phenomenon that is always associated with regulation, makes it necessary to find ways of suppressing it in order to prevent vibration, noise and last but not least damage to the pipeline system.

In an age when valves communicate with each other and sensors are combined with dato transmission tech­niques, the bob综合体育官网下载 -Group is expanding its extensive range of valves for water and wastewater applications with an intelligent system for monitoring and detecting water losses in supply networks: LeakMonitoring 4.0. This special solution includes hardware (sensors) as well as software and makes wiring networks and valves smarter.

Normally butterfly valves are used as on-off valves and are usually installed in a valve chamber on

the water side of bottom outlet lines in dams or in gravity lines leading to water treatment plants or

hydro-power plants. In the best case the butterfly valves are assembled with brake and lift cylinders,

working as pipe brake devices for emergency quick closing by lever and weight in case of pipe

bursts. In dam applications, control valves such as plunger valves (or needle valves) or hollow-jet valves (or Howell Bunger valves or Fixed Cone valves) are installed after the butterfly valves on the air side. These valves always work as flow regulating or control valves. Plunger valves or hollow-jet valves are designed to perform regulating or control functions in water supply systems. Unlike butterfly valves or gate valves assuming only shut-off functions in pipeline systems, plunger valves and hollow-jet valves can meet the requirements of regulating operations.

The protection of our environment asks for sophisticated plant technology and process control. In line with this, the requirements of planners and operators of water supply systems keep increasing with regard to the safe function and reliability of...

Previously, not all requirements for control and regulation valves in water supply could be met. Now bob综合体育官网下载 has developed an automatic actuator controlled by the medium present in the pipeline and with integrated fail-safe function as a multi-turn...
