Often a check valve and a stop valve are installed separately on top of a steamboiler. A check valve prevents you for steam flowing backwards into the boilerssystem and a stopvalve gives you the opportunity to isolate the main steamline. Stahl-Armaturen PERSTA GmbH, with her many long years experience, has developed a solution to combine this check/stop function within a single valve: Stop-Check valve

Advanced Valve Solutions was founded, in 1999, to provide the best possible technical solutions to flow control issues. The Dutch company with UK headquarters in the North West prides itself on service levels and technical expertise. In 2013 UK Director Rik Barry commissioned membership of the British Valve and Actuator Association.

Hora’s valvemate is THE application to calculate water- and steamvalves. With this app it’s possible to do calculations by your own regarding thermodynamical properties of water and steam. ValveMate is very user-friendly with a very easy interface to type in parameters as flow, pressure and temperature. The results will show up in a fast and easy way. Also, ValveMate detects flashing and shows the steamfraction of a mixture at the valve outlet.
