The Olmsted SVX Series of 2-way servo controlled proportional throttling valves are designed specifically for hydraulic applications where very fine
flow control and rapid dynamic response are critical to system performance. The SVX series valves are perfectly suited for high-speed hydraulic applications such as die casting shot control, injection molding and more.
KEY FEATURES:
• Standard cavity sizes NG40 through NG125
*Expanded range available on request
• High-Speed DDV servo pilot valve as standard
• Industry-leading dynamic response for fast and accurate motion control
• Unique flow window design provides superior flow control over a broad range
• Designed for long life in the most demanding high-cycle applications
DESCRIPTION:
The SVX Series valves are a 2-stage cartridge valve design. The main stage features a unique metering sleeve, flow gate, and control spool. An internal LVDT provides position feedback of the control spool for closed-loop proportional control.
Pilot control for the main stage is provided by an NFPA servo valve. The standard offering includes a high-speed proportional servo-controlled DDV, which provides high pilot flow for excellent dynamic response.
Pressure and tank connections for the pilot valve are provided via the X and Y port locations on the valve cap or may be externally connected with pilot lines.
1. Dynamic/Static response is given for the standard provided servo pilot valve. Performance may vary for other pilot valve options.
2. Pilot valve electronics ratings vary based on selected command input. See configuration guide on page 2 for details on signal codes.
