FF-115 is a double flapper-nozzle force feedback, two-stage electro-hydraulic flow control servo valve designed for industrial applications. It serves as an affordable alternative to the Moog G77XK and is specifically engineered for explosion-proof environments. This model is intrinsically safe, making it ideal for use in hazardous areas where safety is a top priority.
Key Features:
- Intrinsic safety protection for use in explosive environments.
- External null adjustment allows users to fine-tune the valve's performance for optimal operation.
- Available in multiple flow rates: 12, 40, 75, 9, and 37 L/min.
- Designed with high precision control and customizable options.
- Certified under national standards and manufactured in Nanjing, China.
- Hydraulic power system ensures reliable and efficient operation.
- Suitable for a wide range of industrial applications, including automation, aerospace, and heavy machinery.
