Steam Conditioning Valves -Steam conditioning engineering is of considerable importance in the steam generating and steam consuming industries, e.g. power plants, pulp and paper industries, seawater desalination plants, breweries, refineries etc.. As the name already implies, steam conditioning is the simultaneous change of both temperature and pressure - pressure reducing and de-superheating station (PRDS). A steam conditioning valve replaces the separate arrangement of a pressure reducing valve and a de-superheater. It requires less space and is more cost effective. 

De-Superheater Regulator -A de-superheater is a regulating device for control installations in many fields of industry, providing precise cooling.

Minimum Flow Non-Return Valves -These protect centrifugal pumps from possible damage caused by thermal and hydraulic overloads at low load operations by means of an automatic controlled by-pass flow which corresponds with the required minimum flow of the pump.

3.10 Applications for Specialist Power Valves - This technical bulletin provides some information on the various applications.

3.10 HORA Turbine Bypass System - A turbine bypass system permits operation of the boiler independently from the steam turbine during start-up, commissioning, turbine trip (shut down) and load alternations. It gives a higher plant availability and operational flexibility over all different operating conditions. The start-up time under cold, warm and hot conditions is reduced. Keeping the thermal transient in the boiler to a minimum continuous flow through superheater and reheater (maintained tube cooling) must be provided and the pressure during the entire start-up has to be controlled. This article describes how the bypass valve achieves this. From www.flowandcontrol.com
