Usage examples

Speed ​​adjustment method

1. Speed adjustment of drive equipment

(1) When increasing the speed
The flow rate increases as the needle of the throttle valve PP is turned counterclockwise from the fully closed state. When the flow rate reaches the desired value, be sure to tighten the lock nut to prevent the flow rate setting from deviating.

(2) When slowing down
If the needle of the throttle valve PP is turned too much (i.e. if the flow rate becomes too high), turn it clockwise to decrease the flow rate. When the flow rate reaches the desired value, be sure to tighten the lock nut to prevent the flow rate setting from deviating.

How To Attach And Detach The Connecting Part

1. How to attach/detach the tube

(1) Installation of tube

By simply inserting a tube until the tube stop, the Throttle Valve PP (Needle Throttle Valve With Quick-Connect Fitting for Clean Environment) fixes it with its lock claws, and the elastic sleeve seals the outer circumference of the tube.
When installing, refer to the precautions "6. Precautions for installing the tube" in the digital catalog.

(2) Removing the tube

When removing the tube, the lock claw opens by pushing the release ring, and the tube can be pulled out.
Please be sure to turn off the air before removing.

2. Screw tightening method

(1) Tightening the screws

To tighten the screws, use a spanner to tighten the hexagonal outer diameter.
When tightening, please refer to the table of Common Control Precautions "2. Precautions for mounting the main unit" and tighten the torque.

Cautions/prohibitions

Warning

1. Selection of pneumatic equipment

(1) The selection of pneumatic equipment should be decided by a person who has sufficient knowledge and experience, such as a pneumatic system designer or a person who decides specifications.

(2) Since the conditions used are diverse, before determining the compatibility with a system, ensure that a person with sufficient knowledge and experience, such as a pneumatic system designer or a person who decides the specifications, perform analyses and tests as necessary. In addition, it is the responsibility of the person who determines the compatibility with the system to guarantee the intended performance and safety of the system. Also after that, please review all the details of the specifications on the latest product catalogs and documents, and consider the situation regarding the possibility of equipment failure before configure a system.

2. A person with sufficient knowledge and experience should handle the pneumatic equipment.

(1) Compressed air is dangerous if mishandled. Ensure that a person with sufficient knowledge and experience performs assembly, operation, maintenance, etc., of machines and devices using pneumatic equipment.

3. Please do not handle machines/devices or remove devices until safety is confirmed.

(1) Before inspecting or servicing machines/devices, make sure that workpiece fall prevention measures are taken and runaway prevention devices are installed.

(2) When removing equipment, make sure that the above safety measures are taken, shut off the supply of compressed air and the power supply of the corresponding equipment, and exhaust the compressed air from the system.

(3) When restarting a machine/device, make sure that measures are taken to prevent popping out and be careful.

• * Please note that cautions and prohibited items are subject to change without notice.
