Self-operated micro-pressure control valve-Shanghai ShangFa valve manufacturing (group) Co., LTD

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.
