Products Description
The FF-130 series electro-hydraulic servo valve is a two-stage dual nozzle baffle flow servo valve with force feedback. Under a pressure difference of 21MPa, its flow rates are 40L/min, 50 L/min, and 60L/min. This series of servo valves adopts a fully stainless steel shell, compact internal structure, high structural strength, and relatively small volume and weight. The installation direction of the plug and socket can be selected according to the needs. The product has the advantages of fast dynamic response, good linearity, zero drift, stable working performance, high reliability, long service life, small internal leakage, and low power consumption. Suitable for small and medium-sized rolling mills, blowing and injection molding machines, testing equipment, etc.
Product Features:
● High control accuracy, fast dynamic response, and easy operation
● Good linearity, strong driving force, and small zero drift
