M35 Series Double Valve

Safety Cat. 4 PL e, External Monitoring with & without Soft-Start

  • Redundant control can achieve Category 4, PL e, when used with proper safety controls
  • Each valve element in the M35 Series is equipped with a solid state pressure sensor for external monitoring
  • Monitoring both of these sensors on each actuation and de-actuation of the M35 Series valve provides a diagnostic coverage up to 99%.
  • Poppet design that is dirt tolerant, wear compensating for quick response and high flow capacity
  • PTFE backup piston rings enhances valve endurance enabling operation with or without in-line lubrication
  • Optional Soft-Start Module on energization, allows outlet pressure to increase at a slower rate until it reaches approximately 50% of inlet pressure, at which point the valve will then open fully to finish filling the system at full rate
  • Modular port connection allows modular connection to Air Entry System (Lockout Valve, FRLs)
  • LED Indicators provides visual display of valve status and aids troubleshooting
  • Include built-in silencer module or threaded flange for remote exhaust
