Description
A self-operated control valve requiring no external energy supply, designed for differential pressure regulation of non-corrosive liquids and gases at temperatures up to 200°C. Two control variants are available: downstream control (valve closes on rising differential pressure) and upstream control (valve opens on rising differential pressure). Features stainless steel bellows pressure-balancing construction with adjustable set points.
