GATE VALVE, PE PIPE ENDS, PN10/16

Features

• Fixed, integral wedge nut in dezincification resistant brass prevents vibration and ensures durability
• Wedge fully vulcanized with drinking water approved EPDM and equipped with wedge shoes that easily slide on the guide rails and provide smooth operation even at high differential pressure
• A large conical stem hole goes all the way through the wedge and prevents stagnant water from accumulating
• Stem in stainless steel 1.4021/1.4104 with wedge stop and rolled threads for high strength
• Full circle thrust bearing in dezincification resistant brass keeps the stem firmly lined up and ensures low operating torque
• Triple safety stem sealing with a wiper ring outermost to protect against contamination from the evironment, in the middle 4 O-rings surround a PA bushing that comprises the radial bearing, and innermost a lip ring is the main seal to the flow
• Round bonnet gasket fixed in a recess groove in bonnet preventing it from being blown out by pressure surges
• Full bore
• Counterbored bolts, stainless steel A2, sealed with hot-melt glue and completely encircled by the bonnet gasket
• 250µm blue RAL 5017 epoxy coating according to GSK and DIN 3476
• 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 as strong as the PE pipe itself. The PE pipe end enables direct welding into PE pipes resulting in a fast and secure assembly. 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
• SDR11 is for PN16 rating and SDR17 is for PN10 rating
• Approved with WRAS certificate
