Johnson Controls P70CA-61 Pressure Control 30067439-890 This bi-directional filter drier design

This bi-directional filter drier design ensures that dirt trapped during the cooling cycle is not flushed back into the system when the unit switches to heating mode

This two-position valve configuration is optimized for mixing or diverting services

For such applications

Over-fusing a circuit risks permanent damage to the primary control board or transformer

this fixed-orifice flow control plate ensures consistent HVAC system performance by managing the pressure drop necessary for efficient phase change
