特点&优势

Unobstructed flow-path provides 70% greater flow capacity for a given valve size

Shaft is designed to safety requirements of ASME B16.34 to prevent the stem from being removed while the valve is under pressure for increased safety

Polygon connection between the shaft and plug provides precise control and substantially longer service life
