Our VG Chainwheel Knife Gate Valves share the same parts as our solidly designed rising spindle handwheel operated valve but with the handwheel replaced by a cast iron chainwheel. Because the operator can be remote from the valve these are often fitted with end of travel switches to indicate the position.  All VG Knife Valves are supplied with the supports pre-drilled to accept our ranges of indicator switches.   Ductile Iron valve has epoxy coated body Stainless valve has self colour body The whole range of seat materials and accessories suits both Ductile Iron bodied and Stainless bodied Chainwheel Plate Valves.   Chainwheel Knife Valve Sizes The VG Chainwheel Slide Valves are available as standard in the following sizes in both Ductile Iron Body and Stainless Body: DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 450, DN 500, DN 600, DN 700, DN 800, DN 900, DN 1000, DN 1200.
