The Valveco Series 728 Resilient Seated Gate Valves from HMA Flow & Industrial feature a ductile iron body and bonnet for high strength and impact resistance. The ductile iron gate is fully encapsulated in EPDM rubber to ensure a tight seal. A Grade SS431 stainless steel stem allows for strength and corrosion resistance. A back-seal facility allows for replacement of stem seals under pressure. Grade SS316 bolts and fasteners provided for added corrosion resistance.
The Valveco Series 728 Resilient Seated Gate Valves from HMA Flow & Industrial feature a full port design. The stem nut is separated from the gate for easy opening and closing, with cast integral feet for safe and easy storage. Lifting eye bolts make for easy installation (150 mm and over). Both clockwise and anti-clockwise closing are available, with key, hand wheel, and gearbox operators. The Valveco Series 728 is suitable for drinking water, wastewater, and other liquids, for above-ground and underground applications.
