HISAKA HF5LP FLOATING TYPE 2-WAY BALL VALVE LOW PENETRATION SEAT

Product Made In Japan
Manufacturer: HISAKA WORK LIMITED
Model: HF5LP

Features

This model uses an LP seat that protects penetration fluid to the material seat in case of monomer fluid.
●PTFE has a void(micro spot hall), but the void of LP seat is quite small. Therefore it has a high performance of protecting penetration for monomer fluid.
●Performance of this seat is high sealing, light & stable operation torque and chemical resistance.
●This seat is able to attach to a standard valve (HF5).
