Dwyer SAV-ST - Manual

The Series SAV Angle Seat Valve offers a compact, low cost
actuated valve package. The pneumatic, externally piloted, piston valve
can be operated with air or liquids, and provides bubble tight shutoff
and failsafe operation. Bronze and stainless steel body materials
provide broad media compatibility and corrosion resistance. The
Polyamide actuator housing resists corrosion for years of maintenance-
free operation. The SAV can be used in most gas, liquid, steam, and
corrosive applications. For ease of installation, the SAV actuator
housing can be rotated 360 degrees.

Each SAV valve is manufactured with one of the following valve
functions:
NC (Normally Closed)
These valves are designed for flow over the seat (port 1 to 2). Caution:
Not recommended for waterhammer prevention.
NO (Normally Open)
These valves are designed for flow under the seat (port 2 to 1). Can be
used to prevent waterhammer on valve closure in liquid applications.
