Pressure Differential (P74JA)
 Pressure Differential (P74JA) |
Product Description
P74JA differential pressure controllers are used in water system of central air-conditioning to balance the differential pressure between the pipe of supplying water (hot/chilled) and the pipe of returning water. Its working principle is: when the pressure differential increases over the set point, the valve opens automatically. Water in the supply pipe runs directly to the return pipe, resulting in a reduction in system pressure differential between supply and return.
Feature:
1. Single pole and double throw (SPDT), totally enclosed non-snap acting switch
2. 1/4 in. flared tube pressure connecting on the sensing component permits easy field installation
3. Easy-read calibrated scale
4. Pressure differential setting can be easily changed without removing the outer shell
