Gate valve for sewage NBR , AISI316 Stem PE pipe ends PN16 AVK

Gate valve with PE100 PN16 SDR11 pipes, NBR, with 1.4404/316L stem. For wastewater to max. 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. 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, 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 NBR 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
• Stem of acid resistant stainless steel AISI 316 with rolled threads providing 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 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, GSK approved
• 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 fully tensile resistant and designed to meet all the criteria specified in DVGW G5600-1. The PE pipe end enables direct welding into PE pipes resulting in a fast and secure assembly.
• Note: For higher working temperatures expect a reduction of the PE pipe’s lifetime. Please refer to the local pipe manufacturer for further information.
