Description: The internal pressure relief valve of the Fisher 67CFR regulator does not provide complete overpressure protection. The internal pressure relief valve is designed for small seat leaks only. Additional overvoltage protection is required if the * maximum inlet pressure of a Type 67CFR regulator exceeds the * maximum pressure rating of its downstream equipment or exceeds its * maximum allowable outlet pressure.
