Pneumatic diaphragm three-way merging regulating valve ZMAQ-16C DN50 pneumatic diaphragm regulating valve

Description :

　　1. Product Overview

　　Pneumatic three-way regulating valve is the execution unit of instruments in automation control systems. It adopts an electric pneumatic valve, powered by electrical signals and compressed air, and receives 0-10mA input from the control system? DC or 4-20mA? The DC current signal is converted by the regulator into a compressed air source pressure signal input and output, which can achieve segmented control (amplitude signal), thereby changing the valve core opening displacement and achieving process parameter adjustment control of the fluid medium Pneumatic three-way regulating valves can be classified according to their operating modes; Positive effect: Air closed Reaction: Air open (when the signal pressure increases, the valve position shifts upward).

　　The valve core structure of the three-way regulating valve is a cylindrical thin-walled window shaped valve core, which adopts side guidance of the valve core, inner surface guidance of the valve seat, and upper liner guidance. Therefore, the guiding area is large and the operation is reliable The direction of fluid action on the valve core is in the open state, so the valve's working performance is stable.

　　There are two forms of three-way regulating valves: three-way merging regulating valve (mixing two fluids into one fluid through the three-way valve) and three-way splitting regulating valve (dividing one fluid into two streams through the three-way valve) When the nominal diameter DN is ≤ 80mm and the pressure difference is small, the diversion valve can be replaced with a merging valve of the same diameter There are two types of flow characteristics: linear and parabolic.

　　A three-way regulating valve can replace two two-way regulating valves used simultaneously, playing a role in diversion or merging and regulating the ratio of two phases.

　　Widely used in the automation regulation and remote control of industrial production processes such as chemical, petroleum, metallurgy, power plants, textile, papermaking, and pharmaceuticals.
