Inproheat is proud to offer SDV valves manufactured by Schroeder.
The SDV is a back pressure device installed to a pipe that contains an integrated check system to maintain a set back pressure. The SDVs functionality remains separate from the pump’s flow rate or volume and it prevents a pumped medium from cavitation or complete vaporization.
SDVs accomplish their primary purpose of maintaining set back pressure through the use of a cone that is spring-activated. The cone activates flow at the desired pressure level and locks into place.
The SDV has a unique control function on the cone to ensure that the valve is not causing any unnecessary noise that can be induced by a lower flow rate.
SDVs contain a built-in return system to prevent any flow from travelling in reverse.
SDVs are commonly used for applications where, under atmospheric conditions, a pumped medium’s temperature is above its vaporization temperature. A prime example would be if the medium is water and it has a temperature at or above 100°C.
