VENT VALVE VVV01 Veljan Vent valve VVV01 are electrically operated 3/2 way devices and are compatible Port Z - Power component with VELJAN pilot operated pressure controls and 2-way seat valves. Due to sandwich X Y Loaded : Solenoid OFF design, these vent valves can be easily installed into existing valves. No extra components Unloaded : Solenoid ON such as subplates, fittings and piping are required. Z PC VVV01 sandwiched between the power component or main body and the pilot section or cap of the valve it is controlling, directs the pilot oil to the power component to allow its Loaded : Solenoid ON designated function at system pressure, or to the pilot oil return to allow unloading. Two Y X Unloaded : Solenoid OFF different control spools are available for the functions. These are for ”Power component Z unloaded in normal position” and “Power component unloaded in switch position”. Solenoids are with manual override and leakproof function. Coils can be changed without interfering with the hydraulic circuit.
