CONTROL HANDLE for linkage model
1010A-C Valves are designed for oxygen service up to a maximum pressure of 125 psi. All valves are for throttling control only and not for tight shutoff. Bodies of all 1010A-C valves are brass. All cores and curtains are Monel and the shafts are stainless steel. The packing is Teflon and all gaskets are Fluorocarbon rubber (Viton). Valves are cleaned for oxygen service, lubricated with PFPE lubricant and shipped in a sealed plastic bag to keep clean. See Sheet 1008A Instructions for lubricating instructions. Dimensions are the same as 1008 Valves, only materials of construction are different. (See pages 4-6) 1008A-C valves are designed for oxygen service up to a maximum pressure of 50 psi and pipe velocities up to 100 FPS. The bodies of 1008A-C valves are ductile iron. All cores and curtains are 316L stainless steel and the shafts are SST. The rest of the valve is constructed and lubricated the same as the 1010A-C.
