The 3DRE and 3DRE(M)E are pilot-operated pressure-reducing valves that can reduce (P to A) and limit (A to T) system pressure. They can be operated by a proportional solenoid. They are suitable for subplate mounting and feature interfaces based on DIN 24340 and ISO 4401 standards.
The 3DRE(M) and 3DRE(M)E are pilot‑operated, 3‑way proportional pressure reducing valves that lower system pressure and can include a maximum pressure relief function. They are supplied with integrated electronics (OBE) or can be used with external control electronics.
