Stager Operation

Stagers are motor driven, rotary multi-port valves used to

control a set of valves in a predefined sequence. They function

by internally connecting inlet pressure to a defined set of

control ports and allowing other control ports be vented through

a drain. Control ports are used to open and close valves in a

preset sequence. As the stager advances to various positions,

different valves are open and closed in a system. The control

port pressure and vent sequence is preset at the factory and

cannot be field altered.

Stager Installation

1. Connect a constant pressure water or air source to the 1/8"

NPT stager inlet. Control fluid pressure must be equal to or

greater than system pressure. To ensure long trouble free

operation, a 100 micron filter in the control pressure line is

recommended.

2. Stager drain port should be left open or discharged to

unrestricted or open drain. DO NOT plug or restrict drain

port.

3. Connect the 1/8" NPT control ports to appropriate valves.

Refer to tubing schematic provided in the Plumbing

Diagrams section of this manual. Tubing inside diameter

should be 1/8" or larger.

Inverted Type Stagers

Stagers that are ordered inverted would be used on systems

with all normally closed valves. Inverted Stagers send pressure

signals to open valves and vent signals to close valves.

Filter Operation Using 48-00 Stagers

When using a 48-00 Stager to operate a filter:

1. Plug stager port #5 using a 1/8" pipe plug

2. Program cycle 2 time to 0:00:00 or the desired settle time
