LINE AND PILOT PRESSURE CHARTS (psi)
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.
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.
