Product Description
Vickers SM4-20 servo valve provides system closed-loop control, with the advantages of high position accuracy, repeatable speed curve and predictable force or torque adjustment.
. the large range flow output capability of the SM4 series ensures that users get the most suitable model.
. the customized valve core cover and valve sleeve opening can meet the special flow control requirements for special purposes.
. the second stage valve body is made of high-strength aluminum alloy to ensure lighter and more durable.
The symmetrical design of SM4 realizes the reliable throttling of flow with the minimum zero offset. As a result, the work of the machine is more coordinated.
. double coil, four air gap, symmetrical dry torque motor, with extremely fast response to input signal, can produce highly accurate control curve.
. Viton * seal is standard.
The standard oil port distribution circle, installation mode and flexibility of transition plate make the wiggs servo valve a high cost-effective alternative to the existing servo valve and improve the existing system.
. higher frequency response (customized) can increase the broadband of the system and meet higher performance requirements.
. an integrated 35 OM (absolute) filter protects the pilot stage from contamination.
. the simple interface of SM4 is equipped with double filter module, which can effectively protect the pilot stage from pollution.
. the valve core and valve sleeve are made of hardened stainless steel to reduce wear and corrosion. The O-ring installed on the valve sleeve prevents the valve core from engaging to ensure smooth operation.
. before installing the SM4, the flushing valve can greatly reduce the initial pollution of the system.
