Abstract: A dry pipe valve is provided which includes a main chamber having an input port for receiving fluid from a supply line and further having an output port. The dry pipe valve further includes a clapper assembly installed in the main chamber for sealing the input port. The clapper assembly includes a clapper configured to seal the input port, where the clapper is hinged to the main chamber. The clapper assembly further includes a hinged lever movable between a first position in which the clapper is held closed by the lever and a second position in which the clapper is allowed to open. The dry pipe valve also includes a pushrod mounted perpendicular to a direction of a main flow through the valve. The pushrod urges the lever against the clapper when the clapper is in the first position. Also included in the dry pipe valve is a pushrod chamber through which the pushrod extends, the pushrod chamber having an inlet that is fluidly connected to an input supply to the valve, and an outlet. The pushrod is in communication with the lever to allow movement of the lever between the first position and the second position. In one aspect, a dry valve actuator is directly attached to a housing of the pushrod chamber and is connected to the outlet of the pushrod chamber. The drive valve actuator is mounted generally perpendicular to the main flow of the valve.
