McDonnell & Miller 94-7B-HD Controller 322838-754 the TD114 provides superior responsiveness

the TD114 provides superior responsiveness compared to traditional mod motors or butterfly valves by sending instantaneous signals to the amplifier for immediate burner adjustment

Precision Power Rating: A calibrated 12W power consumption ensures efficient energy use while delivering 23 VA of inductive power for consistent valve opening

Precision lock-up regulator design prevents downstream pressure equalization during static conditions

It provides the same form factor with updated material resilience for modern environmental standards

an additional external transformer must be integrated into the system

McDonnell & Miller 94-7B-HD Controller 322838-754 the TD114 provides superior responsivenessThe McDonnell & Miller 94 7B HD is a high performance head mechanism only designed for heavy duty commercial and industrial steam applications. As a critical replacement head mechanism for Series 94 and 194 controllers, this unit integrates a combination low water cut off and pump controller to maintain precise boiler water level control. Engineered for systems with a maximum pressure of 250 PSI, it utilizes a 7B potentiometer switch to provide a 135
