Overview
The Mead Fluid Dynamics FT-4 mechanical valve represents a trusted solution for manual control in pneumatic and hydraulic systems. Mead Fluid Dynamics FT-4 valves are compact, mechanically actuated devices designed for foot, hand, or cam-operated control. Built with precision machining and industrial-grade materials, this valve family delivers reliable on-demand flow control without requiring air pilot signal, electric solenoid, or external power sources.
Key Features
- Mechanical foot-pedal or hand-lever actuation—no solenoid or pilot signal required
- Compact aluminum body construction for durability and corrosion resistance
- Hardened steel internal components for extended service life
- Ported design for 3-way or 4-way flow configurations
- NPT and ISO porting options for flexible installation
- Proven performance in single-acting and double-acting cylinder control
