2、 MOOG D661-4436C servo proportional valve from the United States

Brand and Model: MOOG, D661-4436C, USA

Price and Procurement: According to market conditions, the price and procurement quantity of this model of servo valve may vary. Please consult relevant suppliers for details.

Technical specifications:

Valve body material: cast iron

Structural feature: Truncated gate shape

Switch direction: straight stroke

Connection type: flange

Pressure environment: Ultra high pressure valve PN>100.0MPa, pressure environment value can reach 300MPa

Working temperature: High temperature valve, with a relatively high working temperature range

Special feature: Quick type

Nominal diameter: 1mm

Dimensions: 8mm

Weight: 1.5kg

Working principle: The Moog servo valve consists of a permanent magnet torque motor, nozzle, baffle, valve core, valve sleeve, and control chamber. When current is applied to the input coil, the baffle moves and changes the throttling effect of the nozzle, thereby controlling the flow rate and back pressure. The displacement of the valve core is proportional to the input current of the torque motor, and the hydraulic pressure acting on the valve core is balanced with the spring force.

Application scope: It is also suitable for hydraulic control systems that require high precision and high response speed, and is widely used in multiple industries such as steel metallurgy, power station systems, injection molding and blow molding.
