La description
V**0X Self-operated
(regulating)differential pressure control
valve is composed of
control valve body assembly, actuator, positioning spring
,stainless steel bellows, external pressure tap and so on. The
valve doesn’t require any auxiliary energy from external supply
sources, and by use of medium its own pressure as motive power, it
can automatically control and stabilize the medium
pressure.
It is balance
single seat type. It is characterized by steady, high regulating
accuracy , energy conservation ,sensitive action and
convenience to operate and
maintain.
It is widely used for the flue gas of
industrial boiler combustion system and in the automatically
regulating occasion of oil processing, oil tank protecting gas and
heat treatment protecting gas.
