The Parker C-EC-SC Series balance ported thermostatic expansion valves have a brass bar stock body with flare or sweat connections, adjustable superheat, long lasting replaceable power element and accessible internal parts. Each valve is factory tested to ensure positive leak-free performance. The balance port design provides perfect pin and port alignment and prevents pressure drop across the valve from influencing valve operation.

Also available is the Parker C Series Interchangeable valve. These C Valves are supplied in two components, the thermostatic element and the valve body. The interchangeable nature of this part of the C family makes it ideal for reducing inventory, while increasing valve options.

Parker LAC head pressure control valves have a brass body with copper connections. These valves are nonadjustable. They perform the function of limiting flow of refrigerant from the condenser and at the same time regulate the flow of hot gas around the condenser to the receiver during low ambient conditions, so as to keep the refrigerant in the liquid line at proper pressure. Each valve is factory tested to ensure positive leak-free performance.

The ORD valve is a pressure differential valve that responds to changes in the pressure difference across the valve, Figure 6 on the next page. The valve designation stands for Opens on Rise of Differential pressure. Therefore, the ORD is dependent on some other control valve or action for its operation. And in this respect, it is used with the ORI for head pressure control. As the ORI valve starts to throttle the flow of liquid refrigerant from the condenser, a pressure differential is created across the ORD. When the differential reaches setpoint, the ORD starts to open and bypasses hot gas to the liquid drain line. As the differential increases, the ORD opens further until its full stroke is reached at a differential of 10 psi above setpoint. Due to its function in the control of head pressure, the full stroke can be utilized in selecting the ORD. The standard pressure setting for the ORD is 20 psig. For systems where the pressure drop between the compressor and the receiver is higher than 14 psi, an ORD with a higher setting is available.
