Note: Roped Hydraulic lifts require Annual, 5-year and hydraulic relief test to be performed. Never operate a cylinder above rated pressures. The low pressure spool port is trailing the high pressure spool port by a certain controllable angle, and therefore blocks the hydraulic fluid flow causing the poppet valve cylinder to extend. Valves not only control the release of fluid in the cylinder, but often mix gases and fluids as well. A safety valve is a fitting, which, by automatically opening, prevents the system from surpassing a predefined overpressure and is intended to automatically close again after a drop in pressure. They can also have a “fin” welded to the valve stem; the exhaust gas rotating the valve thus decreasing the wear on the seat. Cushion performance and Check valve perdormance improved. FAST & FREE. WARNING: Valve lever (spool) may “stick” (not center) under certain conditions allowing the hydraulic equipment to continue to operate and could cause serious injury, death or equipment failure. The counterbalance valve working principle states that the fluid will be trapped inside the spool under pressure until the pilot pressure overcomes the pre-set value. Read and follow instructions carefully. This second part introduces failure mode considerations for fluid power control systems. Use correct fittings and proper hydraulic oil.
