125mm Dual Pressure Regulator with BW

These advanced-design, strong-bodied, precision- manufactured MODULAR regulators are superior in their ability to overcome dirt and sticky oil during opening and tight closing. Models are available for nearly every control function requirement of industrial ammonia and commercial halocarbon refrigeration.

When the solenoid control module is energized, this valve operates in the same manner as the HA4A Standard Regulator or other pilot functions. When the solenoid control module is de-energized, the inlet pressure is channelled to the higher-setting inlet pressure control module and operates in the same manner as the HA4A regulator. When inlet pressure rises above the higher setting, the control module opens to allow inlet pressure to enter the space on top of the piston which forces the main valve seat to open and regulate flow. Typically used as a combined evaporator pressure regulator and defrost internal relief valve.

This product is a 125mm HA4A Pressure Regulator with Dual Pressure regulation, which includes a weld-in connection style.

Please refer to the table below to aid pressure setting selection. Pressure Ranges C and V will incur additonal costs. Pressure Range C requires a CO2 rated valve.
