Control Valve

Quick Exhaust Valve

RoHS2 Compliant

Best suitable for high-speed drive cylinder.

  • 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.
  • Aluminum 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.


Best suitable for high-speed drive cylinder.

Possible to control high-speed cylinder.

Exhaust needle valve type, whose exhaust port incorporates throttling function, is available.

Tube O.D. 3mm is available for mini type.

Annual 90,000ℓ of air consumption can be reduced by downsizing the tube size ø4mm to ø3mm. (Depending on our conditions.)

Plug-in type is added to mini type. (Only for ø4, ø6mm)

By installing near the actuator, it prevents dew condensation caused by adiabatic expansion.

Quick Exhaust ValveSilencer element

Silencer element for maintenance of standard Quick Exhaust Valves with exhaust throttle.

Detailed Safety Instructions


1.To adjust the speed of the actuator by an exhaust throttle model, gradually turn the needle from the fully closed position to increase the amount of air exhausted. If the exhaust throttle valve is open, there is a risk of the actuator move suddenly and violently. Also, except for exhaust throttle type, check the safety before operating.


1.Clogged element of a silencer ​increases the exhaust resistance. It may cause a deterioration of the entire system due to clogging.

2.When using it as a shuttle valve, be sure to provide a differential pressure. Insufficient differential pressure may cause malfunction.

3.After replacing the element, securely tighten the silencer cover by hand. Note that it is not possible to replace the element of the mini-type quick exhaust valve.

4.For products whose piping direction cannot be changed by body rotation after tightening, adjust within the tightening torque range of the main body.

5.In the case of the exhaust throttle type (EQH), the exhaust port (hexagonal surface) may become dirty or black depending on the usage conditions and frequency, but this is not abnormal.
