Schroeder Valves presented their latest innovation at ACHEMA: the Schroeder High Pressure Valve SHP. This automatic re-circulation valve was developed for high and extremely high pressures and also works reliably under highly fluctuating load conditions and long periods of operation under partial load conditions. This is achieved using a special fully automatic minimum flow control system that ensures that flow never falls below the required minimum specified by the pump. With this innovation, the specialist in protective pump fittings is responding to the requirements of its customers, primarily from the field of power plant and plant construction and the offshore industry.

The SHP builds on existing Schroeder Valve technology. The company already has years of operational experience with almost all of the effective principles and assemblies used. As such the SHP can be considered ‘Proven Equipment’. The individual system components have simply been modified and innovatively combined so that they enhance the dependable and low-wear area of application of the existing technology to meet the increased requirements. Thus, the new SHP-series automatic re-circulation valve enables and promotes the energy-efficient operation of modern power plant facilities.

The SHP takes the general development of higher pressures and temperatures and the increased energy-efficiency requirements into account, the changing way in which plants work was also considered in the development of the SHP. Special load sequence power plants, such as modern combined cycle power plants and coal-fired power plants, are operated at partial load for a large proportion of their operating time, on account of the increasing high proportion of regenerative energy generation and highly fluctuating load conditions.

Each Schroeder Valve undergoes a 100% pressure and functionality test prior to delivery. To ensure this with the SHP, the company is currently adding to their flow test centre a test stand for pressures up to 400 bar.
