The 280 Series is a high pressure, 316 stainless steel, hydraulic rotary direction control valve. It is the ideal solution for control of hydraulic actuators used in arduous environments where internal leakage must be minimised. The valves utilise an optically flat rotary spool with pressure loaded seats, to ensure either zero or near zero leakage (depending on flow size). The 280 Series valve is compatible with water glycol hydraulic fluid.
