Abstract
A trim assembly for a fire protection system valve includes a mounting member and a piping assembly supported by the mounting member. The piping assembly includes a priming line with an inlet for receiving priming fluid from a fire suppressant fluid supply line and an outlet for delivering priming fluid to a priming chamber of the fire protection system valve. The inlet and the outlet are provided at the mounting member. The piping assembly also includes a component, which responsive to a control signal and/or a pressure differential. The component redirects priming fluid away from the outlet of the priming line in response to the control signal and/or the pressure differential for controlling the delivering of priming fluid to the priming chamber of the fire protection system valve. The piping assembly further includes a discharge outlet, with the priming line discharging the priming fluid to the discharge outlet when the component directs priming fluid away from the outlet of the priming line, which is preferably provided at the mounting member.
