Operating Temperature Regulators - Type WM 3-Way Water Mix Instruction Manual

4
CAUTION: Do not exceed maximum pressure differentials for given valve sizes. The maximum differential is the
pressure the valve has against it at shutoff. Too large a differential can cause valve chatter and/or prevent shutoff.
