65mm Electric Motor Compensated Pressure Regulator with Strainer and Flanges

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.

Commonly used for precise room temperature control or liquid chiller control. The controlling motor changes regulator pressure setting in accordance with a temperature controller. The regulator pressure setting is altered as the motor receives a signal from a suitable temperature controller. The motor responds to maintain the balance in the electrical circuit. The rotation of the motor is transmitted through a cam, valve stem, and range spring to the top of the control module diaphragm. An increase in temperature decreases the range spring force on top of the control module diaphragm. This decrease in force on the diaphragm allows inlet pressure to pass through the control module to enter the space on top of the piston which forces the main valve seat open to reduce the evaporator pressure. A decrease in temperature causes an increase in the range spring force. This restricts the flow of inlet pressure to the piston causing a reduction in the opening of the main valve seat, reducing regulator flow by raising the pressure setting.

This product is a 65mm HA4A Pressure Regulator with Electric Motor Compensated Regulation, which includes a strainer and applicable SW flanges. 

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.
