Johnson Controls A70BA-18 Temperature Control Refrigerant Constant discharge from the relief

Constant discharge from the relief valve often indicates a fouled first check

As a critical component for Spence Engineering Type E pressure regulators

allowing the system to resume operation once pressures return to a safe operating range above the set differential

The VM2211 features an equal percentage flow characteristic

suitable for modern high-pressure refrigeration cycles

Johnson Controls A70BA-18 Temperature Control Refrigerant Constant discharge from the reliefThe Johnson Controls A70BA 18 Temperature Control is a heavy duty low limit freeze protection thermostat engineered for critical refrigeration and heating applications. Designed with a single pole, single throw (SPST) contact structure, this "Open Low" control is specifically built to protect HVAC coils from freezing by opening the circuit when the sensed temperature drops to the user defined setpoint. With a temperature range of 15F to 55F and a
