Information
The Series 555 Steel Softseal Valve is a double-faced, resilient seat, internal screw, clear bore wedge gate valve. Designed primarily for the isolation of high pressure natural gas, fitting into steel pipelines. Manufactured with the new Donkin PUR corrosion protection system, enabling burial without need for wrapping of the valve body. To ensure full long term protection, flanges and bolts should be wrapped in line with industry guidelines. Manufactured and approved to specification GIS/V7:Part 1
