UNICON VALVES

V100 Series

Variety of Trim Type
• Various trim designs provide a wide range of flow control, noise attenuation, and Anti-Cavitation control.
Low Emissions Packing and Emissions Free
• Low emissions packing is available to meet environmental safety and emissions control requirements, and bellows seals are available to meet zero emissions requirements.
Suitable for Low Differential Pressure Systems
• Suited for applications where the pressure differential across the valve is relatively low, these valves are efficient in systems requiring fine flow adjustments.
Tight Shutoff
• Tight shutoff capability prevents fluid leakage, which enhances system safety and reduces fluid loss.

V200 Series

Pressure Balancing
• The valve plug receives equal pressure from both the top and bottom sides, allowing for stable operation even under high differential pressure.
• This pressure-balancing design reduces the actuator force required to operate the valve.
Versatile Trim Designs
• P-Port and Window Cage are used for low differential pressure service.
• Multi-hole Cage (single-stage to multi-stage) and Disc Stack are designed for low-noise, anti-cavitation, and flashing services.
Tight Shutoff
• Tight shutoff capability prevents fluid leakage, which enhances system safety and reduces fluid loss.

V300 Series

Mixing and Diverting Functions
• Can combine two fluid streams into one or split one fluid stream into two separate paths. Design
• Typically has three ports – two inlets and one outlet, or one inlet and two outlets.
Flexibility
• Available in various sizes and configurations to meet different application needs.
High Capacity
• Broad and streamlined fluid passages allow a larger amount of fluid to pass through compared to other three-way valves of the same size.
Stable Operation
• Port and cage guiding system ensures stable operation of the plug, regardless of its travel.

V600 Series

No-Friction
• The triple offset eliminates all friction throughout the operating cycle, resulting in a vastly extended valve life.
No-Overtravel
• The triple offset refers to the geometric design of the angled cone disc sealing components.
• Contact is only made at the final point of closure, with the 90-degree angle acting as a mechanical stop, which prevents any overtravel of the disc.
Wide Range
• The non-galling design enables a wide variety of material options and a wide range of applications from low to high temperature and pressure.
Zero-Leakage
• Metal-to-metal sealing allows for higher pressure and temperature applications while still providing tight shut off.

V700 Series

Flanged Body Design
• The flanged body design fully meets ASME Class 150, 300, and 600 standards, reducing piping alignment and installation time.
• The one-piece flanged body is designed to reduce production costs.
Eccentric Rotating Construction
• The shape of the eccentric rotary control valve’s disc provides benefits such as tight shut-off, high flow characteristics, and low unidirectional dynamic force.
• The disc of the eccentric rotary control valve contacts the seat only at the moment of seating due to the eccentric rotating design.
High Capacity Flow Design
• This unique disc design provides high flow characteristics.
• The full port’s Cv is normally 2-3 times greater than that of conventional globe valves.
• The high flow capacity combined with controllability at small openings provides excellent rangeability.
Available for High Temperatures
• Metal seating and hardened trim parts allow use in high-temperature and abrasive services.

V800 Series

Independent Ball and Stem
• The ball and stem are manufactured as two separate pieces to reduce the effect of the side load generated by the pressure acting on the ball.
Anti-Static Design
• The continuity of electrical conductance between all metallic components is guaranteed and certified.
Low Emission Valves
• Accurate machining of stem and bonnet sealing surfaces ensures compliance with the most stringent pollution control regulations. Special “live” seals are available upon request.
Ball Seat Alignment
• Stem/flange mechanical stops ensure control and precise alignment of ball rotation.
Longevity of Life
• Special consideration was given to enhancing the longevity and performance of our valves throughout the design, development, testing, and manufacturing stages. The valve designs, combined with the selection of advanced materials, ensure that long periods of inactivity do not affect operational efficiency.

V860 Series

Tilt-and-Turn Operation Mechanism
• The ball tilts and rotates before contacting the seat, eliminating seal rubbing. This mechanism minimizes wear between the ball and the seat.
Mechanically Energized Seal
• The cam angle at the lower end of the stem ensures the core is tightly wedged against the seat, providing a positive shutoff.
Self-Cleaning
• By tilting the core away from the seat before rotation, a 360° flow around the core surface is created, removing any foreign material.
Low Operation Torque
• With seal rubbing eliminated, the valve rotates easily. The dual action with a special mechanism achieves low operation torque.
Enhanced Durability
• The core surface is made of hardened material, resistant to wear and corrosion, providing a long lifespan.
Top Entry Design
• Allows for in-line inspection and repair after system depressurizing, simplifying maintenance.
Dual Stem Guides
• Reinforced stem slots and robust guide pins regulate the stem’s lift-and-turn movement.
