Butterfly valve ARI-ZIVA 22.014 DN125

Butterfly valve ARI-ZIVA 22.014 DN125

Butterfly valves ARI-ZIVA are used on pipelines with pressure up to PN16, mainly as shutoff valves.

Areas of use:

Industrial plants, equipment in the chemical industry, shipbuilding, special technical building equipment, etc.

Peculiarities:

• The sealing (EPDM, NBR, FPM-Viton) of the shutter ensures complete tightness of the structure.
• Detachable design for seal replacement.
• Solid through shaft provides high reliability and resistance to water hammer.
• The disk and the shaft are rigidly connected to each other by a detachable spline connection.
• The seat has a thickening at the point of contact with the disk, goes into a recess in the body. Due to this, a decrease in the relative deformation of the seat during closing is ensured and, accordingly, the service life of the valves is increased.

Main technical data:

• Working environment: cold, heated and hot water, drinking water, industrial water, etc.
• Nominal diameter: DN25 - DN200, DN250 - DN500 - on request.
• Nominal pressure: PN16, PN6 - PN10 - on request.
• Operating temperature (depending on seal): EPDM -10...+130°С (standard); NBR -10...+80°С; FPM (Viton) -10...+150°C (optional).
• Drive: locking handle, worm gear (standard from DN250), electric and pneumatic drives.
• Accession: interflange.
