STAINLESS STEEL BALL VALVES
2 PC FULL PORT 150 PSI
SAFETY EXHAUST VALVE
The gure 220SE is an ideal safety
option for compressed air applications
with downstream pneumatic equipment.
Conventional shut off valves can trap
compressed air in pneumatic equipment,
creating a potentially dangerous situation.
With the 220SE safety exhaust valve, down
stream pressure is vented through the body
when the valve is in the closed position.
The full port design minimizes pressure
drop and the all stainless steel construction
provides robust corrosion resistance.
Features:
• 150 PSI Max. Pressure
• Full Port
• Blow-out Proof Stem
• Adjustable Packing
• Investment Cast Body
• RTFE Seats
• Threaded NPT Ends
• Stainless Steel Handle
• Locking Lever
• Tapped Hole Mounting Pad for Actuation
or Panel Mount Applications
• Non-Vented Ball
• Installation Arrow (Ensures proper
installation by indicating ow in open
position)

FNW 220 SE Size
When the valve is in the
open position, air from the
compressor is delivered
down stream to pneumatic
equipment.
The bypass on the ball
is not engaged, and seat
compression minimizes
any air loss through
the body.
When the valve is in
the closed position, the
compressor side is blocked
off. The down stream
equipment side is allowed to
ow back past the bypass
and out the vent.
