LPAV150-QF-E-AS-MI

High Vacuum poppet valve with ISO-QF40 flanges

• Pneumatic Actuation
• High purity, corrosion resistant, 304 stainless steel body.
• Made from a formed 321 stainless steel bellows which prevents outgassing, virtual leaks, and particle entrapment between bellows convolutions and extends the life cycle.
• Bonnet seals are Viton®.
• Upon electrical control voltage or pneumatic supply failure, the valve fails closed
• Function reliably in applications ranging from semiconductor manufacturing to high energy physics research to nuclear accelerators
