Series 8220 valves are 2-way normally closed internal pilot-operated solenoid valves designed for steam or hot water service. These valves are made of forged brass with stainless steel internal parts ethylene propylene, TFE/P and or TEFLON elastomers depending upon construction. Series 8220 valves may be provided with a general purpose explosion proof solenoid enclosure.
Features & Benefits
- Higher Flow: Up to 60% more flow than competitors; ASCO’s 3/4” flow equals competitors’ 1” flow
- Longer Life: Floating PTFE diaphragm provides positive sealing, improved durability; up to four times longer than other valves
- 1,000,000 cycles on hot water and 50 psi steam*
- 500,000 cycles on 125 psi steam*
- Improved Serviceability: Threaded bonnet is easy to remove for quick inspection and serviceability; reduces downtime and maintenance costs
- Lower Power: Smaller operator reduces energy consumption on 5 psi differential pressure applications (10.1 watts reduced to 6.1 watts)
- DC Constructions: Quiet design that works with 0 psi differential pressure on hot water and 50 psi steam
- Inventory Reduction: One valve for both steam and hot water
- Short Lead Time: Many constructions available as part of the ASCO Today and 5Day programs to help keep production lines running smoothly
