| P260-1LFA | 15〜80 | MAX. 1.0MPa | 0.03～0.9MPa | 220℃ | FC,FCD | Flange |
- Simply connecting an operational air pressure regulator allows for remote setting of the desired pressure.
- By setting the operational air pressure to zero, the line can be remotely shut off.
- Exceptional performance as a pressure-reducing valve.
- Suitable for explosive atmospheres.
- Compact and lightweight.
- Can be converted to a remote-setting type by replacing a few components, even for an in-use P260 model.

Notes:
- We also manufacture nominal diameters 100 to 150.
- We also manufacture products with a primary-side pressure exceeding 1.0 MPa.
- We also manufacture products with a setting pressure / operating air pressure ratio of 2.
- The Cv value is the same as the P260 type pressure reducing valve.
- The valve body for nominal diameters 15 to 40 is made of ductile cast iron.
