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 maintenancefree 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.

INSTALLATION
1. Prior to Installation, be sure system is not under pressure and all
scale and debris is free from piping system.
2. The valve can be installed in any position, with the direction of flow
as indicated on the inlet/outlet ports by the connection numbers 1 and
2.
3. The actuator can be rotated 360 degrees in the direction indicated
on the product label to facilitate easy pilot mounting connection.
4. Apply thread tape or sealant to pipe threads only.
5. Use hex flats on valve to secure the valve and pipe. Never tighten
the valve by using the actuator to turn.
6. Pipework should be supported to prevent any stress on valve body.

NOTES:
OPERATION
1. Flow direction is from ports 2 to 1 for normally closed valves, For
liquids, flow should be under the seat to prevent waterhammer.
2. Pilot pressure is from 22-150 psi, dependent on process pressure.
Review pilot/media pressure relationship charts before initial system
operation.
3. Optional Series PV Solenoid Pilot Valves can be installed for
operation with 120 VAC power supply (other voltages available).
MAINTENANCE
The Series SAV requires no maintenance. Care should be taken to
make sure that the ratings of the valve are not exceeded with respect
to maximum pressures and temperatures, and that the media is
compatible with all materials.
SPARE PARTS
The Series SAV valve is completely safe to disassemble in the field. A
seal kit is available for all valves and actuator sizes compromising:
piston lip seal, actuator steam O-ring, plug soft seal (PTFE), body seal
and O-ring. Specify valve size and type when requesting a seal kit.
