Refrigerant Flow Control Valve

Capillary tubing regulates flow within lines.

Refrigerant flow control valve.

The h series of safety relief valves are designed to protect refrigeration systems from overpressure situations and feature a high flow capacity. Ball valves and shutoff valves turn flow on and off. Packard refrigeration ball valves turn refrigerant flow on and off to allow for repairs or to recharge refrigerant. Expansion valves are often used to moderate the amount of refrigerant flow available through the system to control temperature based on varying environmental loads along with a pressure feedback system to help maintain the desired setting.

The h series are flanged for easy replacement and can be used in a single or dual relief combination. Check valves prevent backflow. Refrigeration valves install into suction discharge and liquid lines to control the flow of refrigerant in air conditioning and refrigeration systems. Refrigeration valves are ideal for slowing or stopping flow when making repairs and evacuating or recharging refrigerant.

The valve stem is double sealed to prevent rupturing. All the valves have some undesirable side effect such as line pressure drop except it is required by design such as throttling valve. Refrigerant flow control valves are used to ensure the refrigeration system is performed in accordance with the conditions as designed particularly during partial load operation.
