Wivo gate valves are engineered with built-in safety in every aspect. The wedge is fully vulcanized with Wivo's proprietary, drinking water-approved EPDM rubber compound. This ensures exceptional durability, as the rubber can return to its original shape, thanks to the double bonding vulcanization process and robust wedge design. The triple safety stem sealing system, along with the high-strength stem and comprehensive corrosion protection, guarantees unmatched reliability and performance.
● Fixed, integrated wedge nut design prevents vibration and enhances long-term durability.
● Wedge is fully vulcanized with high-quality EPDM rubber, complemented by wedge shoes to ensure smooth operation.
● Wedge and body guide rails provide steady, reliable performance during use.
● Stainless steel stem equipped with a wedge stop and rolled threads, offering superior strength.
● Full-circle thrust collar stabilizes the stem, minimizing free-running torque.
● Triple-layer safety stem sealing system, featuring an NBR wiper ring, a polyamide bearing with four NBR O-rings, and an NBR rubber manchette for enhanced sealing integrity.
● EPDM bonnet gasket securely fixed in a recessed area for better sealing.
● Countersunk stainless steel bonnet bolts, sealed and encircled by the bonnet gasket for optimal protection.
● Full bore design ensures unrestricted flow.
● Low operating torque for ease of use.
● Fusion-bonded epoxy coating meeting DIN 3476 Part 1 and EN 14901 standards, GSK approved for durability and corrosion resistance.
● Visual or remote valve position read-out through a stem-mounted position indicator.
