- ASSE Standard 1003. ( ANST 112.26 )
- CSA Standard B356
- ( ASSE – American Society of Sanitary Engineering )
- ( CSA – Canadian Standard Association )
Options
- Available different Models for Air, Water, Oil, Gas, Steam & Chemical
- LP – Low Pressure Range : 10 – 35 PSI
-
n HP – High Pressure Range :
– Max. Inlet 40 Kg/cm2
– Outlet 12 ~ 25 Kg/cm2 20 ~ 35 Kg/cm2
Example
- Pressure drop needed for fully – opened valve. gate for adjustable Pressure range 3 ~ 9 Kg/cm2 of direct activated pressure reducing valve
- A = B / 4 = 9 – 3 = 1.5 Kg/cm2
- If the setting pressure of outlet 6 Kg/cm2, Pressure of fully – opened valve gate will be P = 6-1.5 = 4.5
- Kgf/cm2 (Outlet Pressure should go down under 4.5 Kg/cm2 to make valve gate fully open )
