Semi sanitary 3-way Hydro Ball valve


This valve is suitable for the chemical industry, where very agressive media are used, i.g. where the media are crystallized and tend to harden, or where there is a severe grind.

Futhermore, it is suitable, where it is required, that the valve can be emptied totally. This is done very easily, as all the cavity is filled out with carbonated teflon.

Working pressure:      Up to 200 bar
Temperature:             Max 180°
Connection:               ½" female thread
Material:                    AISI316L
Boring:                       L-bored
O-rings:                     FPM viton (other materials are available on request)

Actuator according to requirement - pneumatic or electric.
