Critical Technical Advantages
-
Secure Flanged Body Design: The V150 features a one-piece, flanged body that eliminates exposed line flange bolting and reduces the time required for alignment and installation. This design promotes piping integrity and ensures a secure, leak-resistant pressure boundary by removing the gaskets found in two-piece bolted valve designs.
-
Precise Throttling Control: The V-notch ball is precisely contoured to provide a modified equal percentage flow characteristic. This allows for a wide range of control and high resolution, even when the valve is nearly closed, significantly reducing process variability.
-
Ease of Maintenance: A standout feature is that ball seal inspection and replacement can be performed at the valve body inlet. This can be done without removing the actuator or completely disassembling the valve, drastically reducing downtime during maintenance cycles.
-
Rugged Sealing Options: The solid HD (Heavy Duty) ball seal construction is engineered for long service life in demanding applications. The pressure-balanced seal design ensures smooth operation and a tight shutoff across varying pressure drops.
-
Severe Service and Compliance: For plants handling sour liquids or gases, the V150 is available in materials that comply with NACE MR0175 and MR0103 standards. This ensures the valve remains resistant to sulfide stress cracking and other corrosive mechanisms.
-
Fugitive Emission Protection: To meet strict environmental regulations, the V150 can be equipped with ENVIRO-SEAL packing systems. These live-loaded systems utilize very smooth shaft surfaces to provide long-lasting, low-emission sealing.
