AVK PREMIUM 100 GATE VALVE, PE PIPE ENDS, PN16

Features

• Fixed, integral wedge nut prevents vibration and ensures durability. It is made of high strength Silicon-brass DZR CW724R for extra wear resistance
• 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
• Stem of duplex w. 1.4362 stainless steel for extra wear resistance, with rolled threads for high strength
• Triple safety stem sealing with NBR wiper ring / polyamide bearing with four NBR O-rings / EPDM rubber manchette
• Round EPDM bonnet gasket fixed in a recess
• Full circle thrust collar of Silicon-brass provides fixation of the stem and low free running torques.
• Countersunk and sealed stainless steel A4 bonnet bolts encircled by the bonnet gasket
• Full bore
• Fusion bonded 300 µm epoxy coating in compliance with DIN 3476 part 1, EN 14901 and GSK, and external PUR according to EN 10290 type 2 class B for extra cathodic protection.
• 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.
  Note: For higher working temperatures than max. 20°C expect a reduction of the PE pipe’s lifetime. Refer to the pipe manufacturer for further information.
