Overview of ZMBN ZMBN-16 ZMBN-40 ZMBN-64 Pneumatic diaphragm control valve

ZMBN ZMBN-16 ZMBN-40 ZMBN-64 Pneumatic diaphragm control valve has upper and lower valve core balls. The thrust of the fluid acting on the upper and lower valve cores is opposite and close, the unbalanced force is very small, the allowable differential pressure is large, and the rated flow coefficient is larger than that of the single seat valve with the same diameter, but the leakage of the valve is larger than that of the single seat valve. It is applicable to clean media occasions where the leakage requirements are not strict and the pressure difference between the front and back of the valve is large.


Working Principle of ZMBN ZMBN-16 ZMBN-40 ZMBN-64 Pneumatic diaphragm 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
