Description & Features
CV1200 Pressure balanced globe control valve is developed and has the advantage of CV1100, especially in case of very high pressure drops, CV1200 control valve pressure-balanced trim is used to reduce the thrust necessary to stroke the plug by reducing the trim off-balance area. Because the pressure-balanced plug fits closely to the retainer, this trim should only be used in generally clean services.
