Stainless Steel Rotary Control Valve 280 Valve

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.

  • Maximum Pressure: Up to 700 bar, 10,000 psi
  • Maximum Flow: Up to 38 lpm, 10 US gpm
  • Ambient Temperature: -20 to 50°C, -4 to 122°F
  • Media Temperature: -30 to 120°C, -22 to 248°F
  • Porting: Side ported BSPP, NPTF, or SAE, Manifold ported 014 O’ ring on pitch circle diameter (PCD)
  • Material: Steel components in 316 Stainless Steel body. Nitrile rubber (NBR) Seals.
