Ball valve SUS304

RoHS2 Compliant

Anti-corrosion ball valve is ideal for use in special environments.
Stainless steel SUS304 is used for metal parts

  • PPS is used for the main resin parts. PPS: PPS: Excellent heat resistance, flame retardancy (UL94 V-0), and chemical resistance.
  • SUS304 is used for the main metal parts. SUS304: Ideal for use where strength is required or in a chemical atmosphere.
Seal rubber
  • FKM is used as seal rubber material. FKM: Excellent in heat resistance, chemical resistance, and ozone resistance.
  • 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.

Detailed Safety Instructions


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.


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.
