Material Mild Steel, Size 10 Counter Balance Valve, Flow 30 lmin

These are cartridge style standard capacity balance control valves. Counter balance valves with pilot assist are meant for control on over running load. The check valve permits unrestricted circulation from link 2 to port 1. While a direct acting pilot assisted relief valve controls flow ranging from 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate established by the pilot ratio. Features counter balance valves should be set at least 1. 3 times the maximum load induced pressure. Back pressure measurement at the terminal 2 enhances the effective relief setting at a ratio of 1 plus the pilot ratio times the back pressure. Reset exceeds 85% of set pressure when the device operates as a valve standard set. Setting lower than the standard set pressure may result in lower reset percentages. Factory pressure setting established at 30cc/min 2 cu. In/min
