Description
The Ranco O16-503 SPDT High Pressure Control is used in controlling pressure within HVAC systems. This part works with help of diaphragm or bellows type that reacts on pressure changes. When the pressure rises to a certain value, which is set in this case to be between 150 and 450 PSI, the diaphragm/bellows moves and triggers an internal SPDT switch. This switch can then make or break a circuit to enable control actions such as turning on or off a pump, compressor or any other equipment. Advantages of this product include pressure control and monitoring of the system, durability of the product and its adaptability to many industries.
