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.
Selection notes
This control valve is a self-operated differential pressure regulator pattern.
Sizes run DN15 to DN250, in PN16, PN25, PN40.
The body is offered in WCB, CF8 and CF8M, so the grade can be matched to the service rather than the other way round.
Stated service media include non-corrosive liquids and non-corrosive gases.
It is catalogued for Water & Wastewater and HVAC.
Working temperature is 0°C to 200°C.
