PU220AR Brass Solenoid Valve
PU220 Valve part number designation:
PU220AR Valve part number designation.
PU = Brass Solenoid VAlve
22 = 2/2 way (2 ports with 2 positions either open or closed)
0 = Zero rated, will operate from zero pressure or vacuum up to its maximum working pressure.
A = BSP thread (Option N for NPT thread, R for Rc thread)
F = flanged solenoid valve (Option F = JIS10K, F3 = ANSI150Lb or F4 = PN16 flange)
N = normally open function or failsafe open power to close for sizes 3/8 to 1" thread only. Example PU220AN-04 1/2 BSP 2/2 Normally Open.
R = rectangle body
D = Drinking water WRAS approved valves
01, 02, 03 etc = the solenoid valve port size. Examples: 01 = 1/8 thread, 02 = 1/4 thread, 03 = 3/8 thread, 04 = 1/2 thread, 06 = 3/4 thread and 08 = 1 inch
H = high pressure valve model fitted with 18.5 watt Class H higher power coil. This is not a manufacturer option, however it has been tested by them and approved. Standard coil is 15 Watt DIN43650A Class H.
E = EPDM sealing, example PU220AR-01AE 1/2 Brass 2/2 normally closed 1.5mm EPDM seals (PU22D version is WRAS EPDM as standard)
V = Viton sealing, example PU220AV-04
H = HNBR sealing, example PU220NNV-08 1" Brass 2/2 normally open with Viton seals.

Blank = NBR sealing
Voltage = Typically Shako use a number code for this such as 1 = 110vAC, 2 = 230vAC, 7 = 24vAC, 8 = 12vDC, 9 = 24vDC, however we elected to use the actual voltage in the part number to cover all other voltages such as 12vAC, 48vDC, 48vAC, 110vDC, 220vDC and 380vAC.

LED = DIN43650 connector with LED, without this standard plug without circuit, is used. However, we elected not to use this code system as we offer several different types of connector including LED + VDR, Rectified Connector, Connector with 1/2 NPT or M12x1.5mm conduit entry and PWM pulse Width Modulating power saving connector.
E = Is the order code for ATEX solenoid coil EExmIIT4 for hazardous area zones 21 and 22 voltages from 12vDC to 240vAC, however we supply ATEX coils as a separate part number to the valve as there are several ATEX coil options and voltages that are not covered by this code sequence.
