Features

• Wedge of brass CW626N vulcanized with NBR rubber and shaped with guides and a special rubber profile ensuring low closing torques
• 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 NBR rubber manchette
• 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 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: The maximum working temperature of 20°C is set according to the ISO9080 lifetime requirements for PE pipes. For higher working temperatures expect a reduction of the PE pipe’s lifetime. Please refer to the local pipe manufacturer for further information.
