Abstract: The present invention provides a pressure-balanced inertial valve assembly for use in marine seismic energy sources such as air guns. The valve includes a poppet (114) having a first seal and a second seal. A pressure chamber (120) containing a fluid under pressure communicating with the first and second seals to substantially balance the pressure across the seals. An inertial mass is coupled to the poppet. A coil assembly is disposed about the inertial mass. A central guide pin (148) provides guided movement for axial translation.
