Gate valve with PE100/PE100-RC PN10 SDR11 pipe acc. to EN 1555-2 / steel spigot end. For gas -10°C to +20°C. Note: The maximum working temperature is set according to the ISO9080 lifetime requirements for PE pipes, and is therefore not the max. temperature for the valve.

AVK gate valves are designed with built-in safety in every detail and with full traceability of vital valve components. The wedge is fully vulcanized with AVK’s own oil and gas resistant NBR 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 replaceable under pressure, the high strength stem and the thorough corrosion protection safeguard the unmatched reliability.

Variant 46/90-003
Material:	Cast steel
DN:	DN50 - DN300
PN:	PN10
Closing direction:	Clockwise to Close

Features

Fixed, integral wedge nut prevents vibration and ensures durability
Wedge fully vulcanized with NBR rubber and equipped with wedge shoes to provide smooth operation
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 and four NBR O-rings in a stem seal nut of dezincification resistant brass replaceable under pressure. A rubber manchette is the main seal to the flow
Round NBR 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
A standard PE pipe is pressed onto the grooved valve end, locked with a steel ring and sealed with a plastic shrink hose. The boltless, full bore PE end connection is tensile resistant and stronger than the PE pipe itself. The PE pipe end enables direct welding into PE pipes resulting in a fast and secure assembly
