Product description:
ZZC and ZZV self-operated
differential (micro) pressure regulator valve is an actuator without
additional energy products. Available for nominal pressure PN0.1,
PN1.0. Poor (micro) pressure can be adjusted in sections. From
50mm.WC~0.1MPa. Its use is very broad, can be used for industrial
furnace system, control of two materials, such as gas, air flow ratio,
in order~achieve the ideal combustion. For hydrogen-cooled generator oil
seal system~control the pressure difference between the seal oil and
hydrogen~ensure reliable seal. When the differential pressure valve
through the low-pressure end of the atmosphere is the micro-pressure
valve (differential pressure valve negative pressure, pressure, force is
zero).
Features:
1, no need~stop production~adjust the set point;
2, no packing, the valve stem, the activities do not exist under the friction, the seal is absolutely reliable;
3, the implementing agencies sensitive element is extremely sensitive~changes in pressure will be very small Is sensed;
4, the body is a four-way form, so K, B-type can be a common body.
