Deskripsi
Servo Valve
- Series : 072
- Model : 072-1202-43
- Brand : MOOG Inc.
The 72 series flow control servo valve is suitable for three-way and, ideally, four-way applications. It features a high-performance two-stage design, covering a rated flow range of 95 to 225 l/min (25 to 60 gpm) under a pressure drop of 35 bar (500 psi) per valve face. The output stage employs a closed four-way sliding valve core structure, while the pilot stage is equipped with a symmetrical dual-nozzle and baffle mechanism, driven by a dual-air-gap dry torque motor. Valve core position is mechanically fed back via a cantilever spring.
Performance characteristics :
Two-stage flow control mechanical feedback (MFB) valve
Low-friction dual-nozzle pilot stage achieves high dynamic response, high resolution, and low hysteresis characteristics.
High valve core driving force and robust design ensure long service life.
Dry torque motor
Optional fifth port for pilot fuel supply
Available in both models with and without filter cartridges.
Filter cartridges can be replaced on-site, making maintenance more convenient.
