Features

• Handle the challenges of high-temperature fluids

• PTFE and EPDM discs, stainless steel seats, plus high-

temperature coils, help provide long, reliable service life

• Wide range of valve constructions, including straight-

through and slow-closing, with normally closed

and normally open operation

• Specify these valves for the high-temperature

applications found in laundries, molding, steam

atomization, sterilizers, autoclaves, and many others

• Series 8263: direct acting miniature valves

• Series 8267: direct acting straight-through,

self-cleaning design

• Series 8210/8220: pilot operated diaphragm valves

• Series 8220: heavy-duty, pilot operated piston

valves have stainless steel pistons

• Series 8221: slow-closing, anti-water hammer design

• Series 8222: pilot operated diaphragm and piston

valves. Y-body floating piston design
