• 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.
  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
