Features:

Flanged body design eliminates exposed line flange bolting, reduces alignment and installation time, and promotes secure valve installations and piping integrity.
The solid HD ball seal construction provides long service life in demanding applications.
Precise contouring of the Vee-Ball provides a modified equal percentage flow characteristic.
Materials are available for applications involving sour liquids and gases. These constructions comply with NACE MR0175-2002, MR0175-2003, MR0103, and MR0175/ISO 15156.
Ball seal inspection and replacement is done at the valve body inlet, without removing the actuator or disassembling the valve.
The one-piece valve body improves structural integrity of the pressure boundary by eliminating leak paths that could be caused by the gaskets in two-piece, bolted valve designs.
The optional ENVIRO-SEAL™ packing systems are designed with very smooth shaft surfaces and live loading to provide exceptional sealing.
