Valve
Ball valve SUS304
Anti-corrosion ball valve is ideal for use in special environments.
Stainless steel SUS304 is used for metal parts
-
No copper-based metallic material is used in flow paths
-
HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.

*Adhere to the following conditions in case the fluid medium is water or any liquids
Surge pressure must be controlled lower than max. operating pressure when using water or any liquids as a fluid medium.
Tap water in Japan, which is soft water(low mineral content) can be used. Carry out tests under actual operating conditions for using other kind of water.
Be sure to place Insert Ring(WR) into the tubing end when the product is used with water or any other liquids.
Please check the chemical compatibility before use.

Detailed Safety Instructions
Warning
1.Check chemical resistance before using the products, when the fluid medium is chemicals, solvent or mixed gases. Depending on the usage conditions, it may cause damage to the products, the tubing fall-off, and a fluid leakage.
2.Do not use the product if it does not satisfy all the conditions listed in the specifications when the fluid medium is water or liquid. It may cause damage to the product, the tubing fall-off, and a fluid leakage.
Caution
1.Do not use a lubricator on products.
2.Make sure to turn the handle until it stops at 90 degrees. Inadequate turning can cause a poor path connection and insuficient flow.
3.When using under negative pressure, install a vacuum filter on the suction side. Dusts being sucked can cause malfunction of the products and the system.
4.Do not pull out the lock pin, as this will cause the unit to separate. Also, make sure that the lock pin is securely inserted when using.
5.Corrosion resistance varies by operating conditions. Evaluate the compatibility before use.
6.Precautions when installing Bracket for in-line type Refer to the following tightening torque chart when tightening flat head screws to install the bracket. Tighten the screws with appropriate torque. Not doing so could cause damages to the screws or the screws being loosen and the bracket could come off.
7.Precautions when using Handle Lockout The product is not designed for strict tamper-proof and easy to break or tear by a knife or nippers. Deploy a stricter locking system as needed.
8.Precautions when using Swivelling Stopper Do not rotate the handle with excessive torque. Doing so may cause the stopper to become stripped.
Frequently Asked Questions for Valve Series
Since MVM (Micro Switch Pin Type valve) is built in the product, please connect the tube by the following procedure.
1. First find the protrusions on the sides of the product to fix the pedal.
2. Press the fixing protrusions using a tool like a driver.
3. The pedal will be off from the protrusions and then open the pedal cover.
4.
Take out the incorporated spring.
*Make sure not to loose the spring at this step.
5. Pass the 2 tubes for IN and OUT from the plumbing holes on the sides or the backside.
6.
Connect the tubes to IN and OUT ports of the built-in Mechanical Valve(MVM).
*Make sure push the tubes fully by the tube ends.
7. Set back the spring to the initial place and close the pedal cover.
8. Step the pedal and make sure Mechanical Valve works properly. Also check the pedal returns to the initial position when the foot is off.
There are two types of hand valves, two-way valves and three-way valves.
The two-way valve only switches between stopping and flowing air. "-2" at the end of the format is a two-way valve type.
The 3-way valve has a function to stop the flow and exhaust the residual pressure on the OUT side.
How to distinguish between two-directional control valve and three-directional control valve
If it is two-directional control valve type, there is no problem even if it is used in the reverse direction.
Three-way directional control valve type has a residual pressure release function, so be sure to keep the direction.
The Hand valve is for air only. Use Ball valves (20 series, 60 series) for water application.
Check the mounting direction.
The three-way directional control valve has a residual pressure release function, and when the valve is closed, the air on the OUT side is exhausted.
If the mounting direction is reversed, the air on the IN side will continue to leak.
