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

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

ZZVP ZZVP-10 ZZVP-16 Self-actuated control valve is an actuator product without external energy. It can be used for nominal pressure pn01, PN10. Differential (micro) pressure can be adjusted in sections. From 50mm. W.C to 0.1MPa. It is widely used in industrial combustion furnace system to control the flow ratio of two materials, such as gas and air, so as to achieve ideal combustion. It is used in the sealing oil system of hydrogen cooled generator set to control the pressure difference between sealing oil and hydrogen to ensure reliable sealing. When the low-pressure end of the differential pressure valve is connected to the atmosphere, it is a micro pressure valve (negative pressure, end pressure and force of the differential pressure valve are zero).

Working Principle of ZZVP ZZVP-10 ZZVP-16 Self-actuated control valve

The regulating valve is composed of electric actuator or pneumatic actuator and regulating valve. The regulating valve is usually divided into straight through single seat regulating valve and straight through double seat regulating valve. The latter has the characteristics of large flow capacity, small imbalance and stable operation, so it is usually especially suitable for occasions with large flow, high pressure drop and less leakage .The regulating valve is used to regulate the flow, pressure and liquid level of the medium. The opening of the valve is automatically controlled according to the signal of the regulating part, so as to achieve the regulation of medium flow, pressure  and liquid level. The regulating valve is divided into electric regulating valve, pneumatic regulating valve and hydraulic regulating valve

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

·The set value can be adjusted without stopping production;

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

·The sensitive element of the actuator is very sensitive, and very small pressure changes will be sensed;

·The valve body is in the form of four-way, so K and B types can be used as a common valve body.
