    Use weighted pressure relief valves to protect your blower from overheating due to pipe obstructions, closed valves or misapplication. Set the valve’s blow-off point by adding weight plates (sold separately) until you reach your desired pressure. Each plate represents 1/2 or 1 psi. To adjust, simply remove the valve’s snap ring and add or remove plates as needed.
