Overview of ZZVP ZZVP-10 ZZVP-16 Self-actuated control valve

ZZV self-operated differential (micro) pressure regulator is a kind of actuator products that do not need additional energy. Can be used for nominal pressure PN01, PN10. Differential (micro) pressure can be adjusted in stages. From 50mm.W.C to 0.1mpa. Its use is very wide, can be used in industrial combustion furnace system, control two kinds of materials, such as gas, air flow ratio, to achieve ideal combustion. Used for sealing oil system of hydrogen cooled generator set to control pressure difference between sealing oil and hydrogen to ensure reliable sealing. When the differential pressure valve low pressure end through the atmosphere is micro pressure valve (differential pressure valve negative pressure, end pressure, force is zero).

The characteristics of ZZVP ZZVP-10 ZZVP-16 Self-actuated control valve

· Adjust the set value without stopping production;

· No packing, there is no friction when the stem moves up and down, and the upper seal is absolutely reliable;

· The actuator is very sensitive, and the slightest pressure change can be detected;

· The valve body is in four-way form, so type K and B can be used as one valve body
