Lined Ball Valve

Re-engineered!

1-Piece Ball and Stem

ASME CLASS 150 • SIZE 1/2" to 6"

MAIN PRODUCT FEATURES

MAIN PRODUCT FEATURES

Full Port Design

Straight-through, full-size round port ensures unrestricted flow, delivering high efficiency and minimal pressure loss.

Low Emission Live Loaded Stem Seal

Fully adjustable stem seals with pre-compressed PTFE packing rings, paired with default packing glands, for reliable long-term, trouble-free service.

1-piece Ball & Stem

Eliminating internal failure points and drive-key wear, delivering high-torque durability and precise alignment in aggressive service.

Advanced Unpigmented PFA Lining

Virgin PFA Lining no contamination fluid handling and body and stem locking grooves to prevent liner collapse under severe conditions.

ISO 5211 Mounting Interface

Standard ISO 5211 actuator mounting dimensions enable the integration of standardized hardware, resulting in a competent valve-actuation package.

V-port evolution

Standard 2-Piece V-Port Opening

Exposed Flat-Seat Geometry
Susceptible to chemical erosion and degradation over time, requiring frequent maintenance and component replacement.

Moderate Pressure Sealing
Degrades under continuous cycling, increasing the risk of inline leakage and unplanned system downtime.

Localized Cavitation & Seat Wear
High-velocity flow across a thin seat edge causes localized turbulence, wire-drawing, and uneven seat erosion during throttling.

Integrated 1-Piece V-Port Ball & Stem

Heavy-Duty Solid Molded Wall
1-piece ball with a thick PFA lining, providing superior corrosion resistance and extended service life in erosive fluids.

High-Pressure Zero-Leakage Seal
Enhanced wall rigidity maintains consistent high-pressure sealing contact, eliminates inline leakage, and reduces downtime.

Optimized Flow Dynamics & Balanced Load
The integrated 1-piece V-port evenly distributes fluid pressure, minimizing seat wear and ensuring linear throttling control.
