I. Product Description

ZMAP Type Single-Seat Pneumatic Diaphragm Control Valve, ZMAN Type Double-Seat Pneumatic Diaphragm Control Valve: Composed of two main parts—the pneumatic diaphragm actuator and the control valve—it works in conjunction with pneumatic regulators, pressure reducing valves, and other instruments to control process parameters such as temperature, pressure, liquid level, and flow rate within pipelines. The single-seat control valve offers advantages such as easy sealing and low leakage, but it has a relatively high unbalanced force, making it unsuitable for high working pressure differentials. The double-seat control valve features a large flow coefficient and relatively low unbalanced force, making it widely applicable.

II. Product Features: ① The single-seat pneumatic diaphragm control valve is characterized by easy sealing and low leakage, but due to its high unbalanced force, it is not suitable for high working pressure differentials. ② The double-seat pneumatic diaphragm control valve offers advantages such as a large rated flow coefficient and low unbalanced force, making it widely used.
