zzvp,zzcp self-operated micro-pressure regulating valve product description:
zzvp,zzcp self-operated micro-pressure regulating valve produced and sold by woci valve group 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).
zzvp,zzcp self-operated micro-pressure regulating valve 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.
