Directional Control Valves
At Hunt Valve, our directional control valves are specifically designed for service on low-viscosity media such as water, 95/5 and other fluids that are commonly utilized in steel and aluminum production applications. These valves are ideal for a variety of low-viscosity applications—from pump unloading to coil handling—due to their corrosion-resistant materials, rugged zero-leakage design and ease of maintenance.
Hunt Valve manufactures both spool and poppet type directional control valves:
- The Combo valveTM incorporates an NFPA mounting interface and is designed to interface with our mod-stack cartridge valves to provide a complete system solution for other functions such as flow control, pressure relief, pressure reducing, check and isolation. The solenoid-operated Combo valve has an energy-efficient, packed-spool design that provides years of reliable service on low-viscosity applications.
- The MVO34 is an updated rugged plunger valve that has been used in steel and aluminum applications for over 75 years. Its rugged plunger design is capable of operating in extremely dirty applications where filtration is minimal. This valve is actuated by an air cylinder to enable operation in very dirty environments. The MV034 can also be used in high-flow applications of up to 400 gpm. Applications for the MV034 range from steel mill descaling to aluminum mill coil handling.
- The poppet directional control valve utilizes zero-leakage poppet technology that is controlled via a ceramic spool pilot valve for ultimate reliability. The dirt tolerance of the ceramic spool pilot eliminates the need for filtration. Hunt Valve’s poppet directional control valves feature integral flow controls. The valves are available in 2-, 3- or 4-way configurations and may be requested with NFPA and custom mounting interfaces.
Smooth, shockless shifting is a built-in design feature of Hunt Valve’s poppet style and spool valve designs. Our ceramic seated poppet valves control shock via proportional control electromechanical actuation. Hunt Valve’s spool valves use special flow slot and seal configurations to manage shock.
Specialty Valves for Hydro Applications
Our directional control valves are manufactured with the high-quality design features required for raw water hydraulic applications such as spherical valve seat actuation. Our water hydraulic directional control valves are among the world’s most reliable valves for these applications.
Proportional Flow Control Valves
Our proportional control valves feature special profile ceramic poppets and are controlled by an electromechanical actuator. The proportional valve provides quick, responsive control with precise positioning capabilities in raw water applications.
