Control Valve
Throttle (Needle)Valve Brass
Not only the body but the release ring is made of brass, thus best suitable for high heat and spatter environments.
-
HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.
Advantages
Not only the body but the release ring is made of brass, thus best suitable for high heat and spatter environments.
It is compatible with special specifications.
HNBR is used for seal material. FKM specification is also available as option.
No cover type is also standardized for a variety of applications.
No cover type is recommended for the applications which does not require spatter resistance.
Specifications
Seal rubber material:HNBR
Fluid medium | Air, Water (Conditional*) |
---|---|
Max. operating pressure | 1.0MPa |
Max. vacuum | -100kPa |
Operating temperature range | 0~100℃ (No freezing) |
Warning
* Make sure to follow the instructions below when the fluid medium is water.
Surge pressure must be controlled lower than max. operating pressure when using water as a fluid medium.
Tap water in Japan free from foreign substances or contamination can be used. Carry out the evaluation under an actual operating condition for using other kind of water.
Be sure to place Insert Ring (WR) into the tube edge when using water as a fluid medium.

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.
3.Do not use this product unless all the conditions described in this specification are satisfied if the fluid medium is water. It may cause damage to the product, disengagement of the tube, or leakage.
4.When using the product in a high temperature environment, select the seal material after taking a sufficient safety factor. The sealing material may leak due to thermal degradation, etc. Regular maintenance should be carried out and the product should be replaced as soon as possible if leakage is detected.
5.The product has a choice of seal rubber material, but there is no identification by seal material. When opening the package, do not mix it with other seal materials. Mixing of different material models may cause a situation that is different from the user's intention.
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.
2.When using covered tube with the fitting with cover, cut the outer cover of tube to the specified size (refer to the following table). Cutting outside of the specified dimensions may cause the tube to come loose, leak, or cannot be inserted properly. * Anti-spatter Tube Cover Peeler (TSC) makes it easy to peel the cover.
