MOD. 5202 PN 25 DN 50-250

Flanged connection, stainless steel fasteners.

SPECIAL FEATURES

• Single orifice type, fully automatic double function
for releasing air during pipe filling and bringing air
in (anti-vacuum) during pipe emptying.

• Performances according to the requirements of
EN 1074.

• Body and cover high quality polyamide (Rilsan – PA11)
powder coated (fusion bonded), coating thickness
DFT min. 250 micron, zero porosity (tested with
3000V), high impact resistance and cross-linkage
according to DIN 30677-2 and DIN 3476.

• Float from non-corrosive material.

• Body provided with threaded drilling for discharging
ball valve connection (available on request).

• Cover provided with threaded drilling for automatic air
valve connection (to obtain a triple function device).

• Flanged connection with multi-size universal drilling to
