Screws: 302 SS
Diaphragm Seat: PA-6 (standard), Viton coated mild steel or High Density PE Refer to Q Series Solenoid product data sheet for solenoid construction details.
Operation
Recommended on time range: 50-500ms
Recommended time between pulses: 1 minute or greater
Maintenance
Before conducting any maintenance activity on the system ensure that components are fully isolated from pressure and power supplies. Pressure and power should not be reapplied until the valve has been fully assembled. Diaphragm and pilot inspection should be conducted annually.
Approvals
Integrally piloted valves meet the requirements of:
. Atex II 2D Mechanical
. CSA (C&US)
C22.2 No. 139-1982 UL Std No. 429
. C-Tick - integral pilots
. EMC (89/336/CE) - integral pilots
Installation
1. Prepare supply and blowtube pipes to suit valve specification. Avoid installing valves underneath the tank.
2. Ensure tank and pipes are free from dirt, rust or other particulate.
3. Ensure supply air is clean and dry.
4. Mount valves to inlet pipes and blowtube to valves, ensuring no excess thread sealant can enter the
valve itself.
5. Make electrical connections to
solenoid or connect RCA pilot port to pilot valve (RCA
valves only).
6. Apply moderate pressure to system and check for installation leaks.
7. Fully pressurise system.
8. Test fire and listen for proper actuation and crisp pulse noise.
