Greater throttling accuracy — Single pivot-point, splined shaft minimizes lost motion between shaft and actuator, ensuring greater accuracy. Improved uptime — Long-lasting, bubble-tight shutoff for improved leakage resistance. WebFlashing conditions can create valve damage as well, but this is typically less pronounced than cavitation damage, and is usually worse at very low valve openings when the valve flow is probably not choked. As the valve opens further, the flow may become choked, but the valve damage will likely be reduced as the plug moves away from the seat ... small upright freezer energy star
