Working principle and structural characteristics of 550 series servo valve

STAR servo valve is based onPrinciple of electromagnetic force hydraulic pressure feedback balanceThe core structure of the work includes:

1. Permanent magnet torque motorConvert the input current into mechanical torque to drive the baffle to deflect;

2. Nozzle baffle mechanismBy adjusting the displacement of the baffle, the hydraulic oil pressure difference is changed to control the movement of the valve core;

3. Force feedback deviceEnsure that the displacement of the valve core is linearly related to the input current to improve control accuracy;

4. Sapphire componentsThe feeder pole and terminal port are made of sapphire material, which has better wear resistance than traditional metals and extends their service life

3、 Core design features

1. Sapphire material feeder pole and terminal port

• The feeder pole is made of sapphire material, which is more durable than diamond and resistant to wear and tear, significantly extending its service life (third-party verification life exceeds millions of times).

• The final port also uses sapphire to prevent import contamination and wear, and improve dynamic response stability.

2. Mechanical structure and performance advantages

• Double stage nozzle baffle designCooperate with low-quality high-frequency wide torque motors to achieve high-resolution and low hysteresis control characteristics.

• Valve core rotation technologyReduce friction and enhance dynamic response capability through rotation, suitable for high bandwidth scenarios (frequency response up to 200Hz).

• anti-interference capabilityThe sapphire feeding rod can resist pulse interference, reduce the risk of ineffective speed change and drift.

If confirmation is needed550-0327For detailed parameters, please refer to the following steps:

1. Contact the supplier to verify the model
   STAR servo valve models may includeRevision number or custom code(such as "650-0031XM501336-0138-100-27"), it is recommended to provide the complete model to authorized dealers such as Ningbo Bingsheng and Shanghai Qiuteng to obtain a certificate of origin or technical manual2.

2. General troubleshooting plan
   If the device encounters common problems similar to the 550 series (such as no action, delayed response), priority can be given to checking:

• control voltageEnsure compliance with rated values (typically ± 10V or ± 20mA signal)

• Oil cleanlinessImpurities may cause the valve core to get stuck, and the filter needs to be replaced regularly

• coil resistanceUse a multimeter to check the coil resistance. If it is abnormal, replace the torque motor

STAR servo valves play an important role in multiple industrial fields due to their high performance and reliability. Its main features include:
