Control Valve

Throttle (Needle) Valve

RoHS2 Compliant

Throttle valve controls the operation speed of a pneumatic device and the transmission of air pressure signals.
The flow rate can be adjusted while the air is flowing.

Resin
  • PBT is used for the main resin parts. PBT: A standard resin material that is ideal for general environments.
Metal
  • Brass with electroless nickel plating is used for the main metal parts.
Seal rubber
  • NBR is used for the seal rubber material. NBR: A material generally used as a sealing material. Please note that it is inferior in ozone resistance.

Options

  • Fluorine grease is used as grease, and the product is packaged in a clean room after cleaning with clean air.

Advantages

Throttle valve controls the operation speed of a pneumatic device and the transmission of air pressure signals.
The flow rate can be adjusted while the air is flowing.

The lead-out directions are free.

Detailed Safety Instructions

Warning

1.To adjust the speed of the actuator, gradually turn the needle from the fully closed position to increase the air volume. If the needle is open, there is a risk of the actuator move suddenly and violently. Turning the needle clockwise closes the valve, while turning it counter-clockwise opens it.

2.When adjusting the flow rate of the equipment, the needle should be turned to open gradually from the fully closed position. If the needle is in open position, a high flow rate will be instantly applied to the equipment and there is a risk of damage to it.

Caution

1.Leakage is allowed for the control flow even when the needle is fully closed position and should not be used in such a way that zero leakage is required.
