RUBBER SEATED BUTTERFLY VALVE MAIN FEATURES:
» Lockable Lever
» Site maintanence
» Ease of automation
» Positive tight shut-off
» Optional top flanges to ISO 5211
» Integrated long-neck body ease the pipeline insulation, and installing actuating device.
» Specially finished disc sealing surface, minimizes operating torque, improves long service life of seat and reach the air-tight sealing;
» Hollow disc design, withstands high pressure,with light weight and low flow resistance.
» The outer edge of seat rubber exceeds body ends, functioning as flange gasket.
» Through-out bolt or one-side bolt used for flanged type butterfly valve, easy replacement and pipeline maintenance.
» Shaft and disc connected without pin to achieve best match and opening torque transmission, reducing leakage points.
» Manual, electic and peneumatic actuator are available.

The ZGV wafer style resilient seated butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.

ZGV  Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.

ZGV offers Rubber seated butterfly valves in Wafer, flanged, lugged and Grooved ends connections, Size Ranges from 1 1/2" to 120"- 40mm to 3000mm, Acutations can be Manual, Pneumatic, Electric, Hydraulic (Counterweight) & Electro-hydraulic; in a broad line of materials of cast iron, ductile iron, stainless steel, duplex to special alloys, suitalbe for a wide range of service mediums from general industrial applications to most severe areas.
