Information about the pressure regulator "after itself" RA-A 50-25-1-SCH-1,6-150- U
Direct-acting pressure regulators of the 100 series, RA-M - pressure drop, RA-A - “after itself”, RA-B - “before itself” PN 1.6 MPa
Y is the setting range, MPa:
- 0,04-0,16
- 0,1-0,4
- 0,3-0,7
- 0,6-1,2
XXX - Kvy throughput, m3/h
Appointment
The regulator is designed for installation in heating and water supply systems for cold and hot water or a 30% aqueous solution of ethylene glycol with a temperature of no more than 150 ° C and a pressure of no more than 1.6 MPa.
