Pneumatic valve specifications
NO = Normally Open
NC = Normally Closed
C = Common
CAUTION : Supply pressure of air/inert gas = min. 2 and max. 7 bar
Note:
- The minimum differential increases with the setpoint. The differential values mentioned in the above table are approximate maximum for FSR. The differential value will vary according to the pressure range selected and microswitch type. For actual values of differential please contact sales office.
If actuation and/or deactuation at same point is critical part of operation, then it can be achieved by using a separate DPDT relay. This relay will need a separate power supply for it’s coil.
HOW TO ORDER HIGH RANGE AIR RELAY SWITCHES
eg. Flameproof air relay switch in aluminium housing with PU tube 4mm OD, fixed differential without scale, having 0.5 bar to 10 bar pressure range, with NC valve, SS316 pressure housing with ¼” BSP port size & neoprene diaphragm shall be specified by
| Group 1 | Group 2 | Group 3 | Group 4 | Group 5 | Group 6 | Group 7 | Group 8 |
| ▢ | FC | A1 | P1 | H01 | P1 | S1 | 1 |
Please specify full model number to avoid ambiguity.
