Speed controller Push-lock type with Indicator

RoHS2 Compliant

Speed setting can be checked with indicator.
Easy adjustment due to its liner characteristics.

  • PBT is used for the main resin parts. PBT: A standard resin material that is ideal for general environments.
  • 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.
  • HNBR is used for the seal rubber material. HNBR: A material with improved ozone resistance by adding hydrogen to NBR. Ideal for low-concentration ozone countermeasures.


Speed setting can be checked with indicator.
Easy adjustment due to its liner characteristics.

Flow rate can be set with indicator. The scales are on the side(upper/lower) and the top.

Flow rate is proportional to the knob turns.

2 types with different flow range for each size are available. Easier fine adjustment is possible in each flow range, compared to Pisco conventional standard speed controller.

It has a very compact body. The industry's smallest and low profile as a speed controller with an indicator.

Push-Lock type knob. Easy to handle.

Flow rate can be set by 30 steps in one turn. * The number of turn is visible every 1/2 turn.

Easy to identify the flow direction by the knob color.

The indicator window of Union straight type can be rotated 360°.

The material of the diaphragm is HNBR.

Detailed Safety Instructions


1.When adjusting the speed of the actuator, the needle, inside the product, should be gradually opened from the closed position near the dial indication "0". When the needle is open, a large flow of compressed air is instantly supplied and there is a danger of the actuator moving suddenly and violently. The operation depending on the direction of rotation of the adjustment knob is as follows. Clockwise (- direction): the needle valve closes, the control flow is reduced and the actuator speed is reduced. Counter-clockwise (+ direction): the needle valve opens and the control flow increases and the actuator speed increases.

2.When adjusting the position of elbow fittings, do not apply pressure to the inside of the product.

3.When adjusting the direction of the dial display window on union-type models, do not apply pressure to the inside of the product.


1.Leakage is allowed for the control flow even when the needle is fully closed in the state of dial indication "0" position and should not be used in such a way that zero leakage is required. Also, depending on how hard the needle is tightened, it may shift from the position where the dial display is "0".

2.Flow rate characteristics are reference values for the product alone and vary depending on piping, circuit, pressure conditions, etc.

3.The adjustment knob is locked when pushed and released when pulled. Be sure to lock it after adjustment. Do not hold the side of the knob too tightly when operating, as it may not be able to unlock it.

4.Be sure to lock it after adjusting the flow rate. If used without locking, the adjustment knob may rotate and the flow rate may change.

5.When pushing in the adjustment knob, depending on the adjusting position, it may stop in a half-locked position between the locked and unlocked states. Make sure that the adjustment knob is pushed completely in to the locked position, as the knob is not fully locked in this state.

6.If the adjustment knob is forcibly rotated while it is in locked position, the lock mechanism may be damaged.

7.Do not turn the adjustment knob excessively counter-clockwise (+ direction) from the fully open position or clockwise (- direction) from the fully closed position. It may cause damage to the adjustment knob and the product.

8.The control range varies depending on the size. When adjusting the flow rate, check the current dial reading and adjust it within the indicator adjusting range shown in the following Table.

9.The direction of the dial indication window on the union type should only be adjusted after ensuring that the spanner is securely applied to the hexagonal-column. There is a risk of deformation or interference with the adjustment knob.
