Features & Benefits
- 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
