Product Summary

Back pressure control valve is designed to relieve excess pressure in the biogas line to the waste gas burner. It is also ideal for directing gas flow sequentially to boilers while maintaining a minimum pressure in the system. It is widely used for research labs, research sampling systems, manifold systems, petroleum industry and testing of components.

Back pressure control valve accurately controls pressure of fluid on a primary side but is not affected by pressure variations on a secondary side. The back pressure control valve has a first chamber, a second chamber, a flow path with a valve seat, a valve mechanism with a rod portion with a valve portion, a first diaphragm within the first chamber which is provided with a first pressure adjusting mechanism M1, and a second diaphragm within the second chamber which is provided with a second pressureadjusting mechanism. And the large diaphragm provides sensitive operation while the compression spring and visual indicator allow for easy field adjustment of the valve setting without removing the valve from service.
