High pressure single-seat valves to regulate the Angle of concrete parameters
High pressure single seat Angle adjustment overview of high-pressure single-seat valve Angle adjustment valve, referred to as 'HPAS regulating valve, is one of the CV3000 series products. High-pressure single-seat Angle valve is a kind of direction structure adjustment valve, the valve body small pressure drop loss, large flow, adjustable range, according to the pipeline to layout requirements, selects the Angle of the valve. The valve core area is large, good vibration resistance. Single-seat regulating valve with more spring loaded diaphragm actuator, compact structure, big output force. Angle valves can be widely different temperature of high pressure fluid control. High pressure single seat Angle adjustment valve leakage in main performance: in accordance with ANSIB16. Level iv, 104 less than the rated Cv of 0.
