Gate valve with Supa Plus™ tensile couplings for uPVC and PE pipes. For drinking water and neutral liquids to max. 70°C

AVK gate valves are designed with built-in safety in every detail. The wedge is fully vulcanized with AVK’s own drinking water approved EPDM rubber compound. It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The triple safety stem sealing system, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Features

Fixed, integral wedge nut prevents vibration and ensures durability
Wedge fully vulcanized with drinking water approved EPDM rubber and equipped with wedge shoes to provide smooth operation
Large conical stem hole in the wedge prevents stagnant water
Wedge and body guide rails ensure stable operation
Stainless steel stem with wedge stop and rolled threads for high strength
Full circle thrust collar provides fixation of the stem and low free running torques
Triple safety stem sealing with an NBR wiper ring, a polyamide bearing with four NBR O-rings and an EPDM rubber manchette
Round EPDM bonnet gasket fixed in a recess
Countersunk and sealed stainless steel bonnet bolts encircled by the bonnet gasket
Full bore
Low operating torque
Fusion bonded epoxy coating in compliance with DIN 3476 part 1 and EN 14901, GSK approved
The valve sockets are fitted with a combined EPDM gasket and tensile ring of RG5 bronze for PE and uPVC pipes allowing angular deflection of ±3.5°. The compression type gasket makes it easy to insert the pipe end, even in large dimensions. External bolts prevent corrosion as there are no threads in the casting
