In June 2005 and starting with serial # 12039, Brownie’s made a technology update to our Valve Plate Assembly. For a clear indication that your system has the OLD style valve plate, you will need to open it up and view it. IF the valve restraint on your valve plate is black and plastic, you have the older style. The current style is Aluminum.
A complete valve plate consists of:
1 Valve Plate
2 Flapper Valves (1 per side)
2 Valve Restraints (1 per side)
