Segmented ball controls very low flow rates and can open up to large flow rates, resulting in a 300:1 turndown

Segmented ball provides shearing action as it moves through the seat to cut through debris and provide reliable shutoff

Metal, soft, and heavy duty seat options provide reliable tight shutoff for a variety of applications and process conditions

Simple rotary action provides options for scotch-yoke and rack-and-pinion actuation, as well as rotary piston cylinder

Cost-effective control for less severe service applications, without compromising flow characteristic

The flexible metal seat uses the pressure drops across the seal to enhance its shut-off characteristics in both directions

Severe service trim options available for cavitation elimination and gaseous noise reduction
