4.4 FLOW SETTING

Flow and pressure is specified at the time of order per the new ordering matrix. The specified flow/pressure disc will be installed at the

factory. The nozzle will NOT be sent with extra flow/pressure discs. If the flow/pressure must be changed, request the appropriate flow/

pressure disc kit. Each kit contains a complete set of flow/pressure discs and necessary hardware.

5.0 NOZZLE CONTROLS

5.1 FLOW CONTROL

5.1.1 METRO 0 & 1 LEVER TYPE FLOW CONTROL 

(SLIDE VALVE)

On models that use a lever type valve handle, the nozzle is shut off

when  the  handle  is  fully  forward.  Slide  valve  models  have  detented

flow  positions.  These  detent  positions  allow  the  nozzle  operator  to

regulate the flow of the nozzle depending on the need or what can be

safely  and  effectively  handled.  TFT  recommends  the  use  of  a  pistol

grip for easier handling. For additional stress reduction, a hose rope or

strap may also be used. This permits more effective use and ease of

advancement, while minimizing strain and fatigue.

5.1.2 TIP ONLY

Tip Only nozzles have NO shut-off valve within the nozzle

and MUST be used with a separate ball valve attached to

the nozzle.

5.1.3 METRO 2 LEVER TYPE FLOW CONTROL (BALL VALVE)

Models  with  a  ball  valve  are  shut  off  when  the  valve  handle  is  fully  forward.  Pulling  back  on  the  handle  opens  the  valve.  TFT

recommends the use of a pistol grip for easier handling. For additional stress reduction, a hose rope or strap may also be used. This

permits more effective use and ease of advancement, while minimizing strain and fatigue.

5.1.4 TWIST SHUTOFF

On models that use a twist flow control, the valve is opened or closed

by rotating the valve ring. Rotating the ring clockwise (as seen from the

operating  position  behind  the  nozzle)  closes  the  valve,  while

counterclockwise  rotation  opens  it.  Detents  are  provided  at

intermediate  positions.  The  position  of  the  valve  is  shown  by  the

exposed valve flow pattern label.

NOTICE

Control valves must be opened slowly to eliminate unnecessary strain on the hose and couplings, 

and reduce pressure surges. 

NOTICE

Nozzles attached to an in-service hose shall be stored in the off position. 

NOTICE

In partially open positions, a ball valve will cause turbulence and adversely affect stream quality.
