ZXM series pneumatic membrane sleeve valve is a kind of pressure balance control valve. Equipped with multi spring actuator, the compact structure, light weight, good stability. Fluid channel is S streamline, pressure drop loss, allows the pressure difference is big, the noise is small, the circulation ability is big. Widely used in precise control of gas, fluid and other media parameters such as pressure, flow, temperature, liquid level to maintain a given value. Especially suitable for large flow, pressure difference, low leakage requirements of the occasion.
This series of products have the standard type and regulating cut off type, bellows seal type, jacket insulation type and other varieties. Product nominal pressure level is PN10, 16, 40, 64; body diameter range DN20~200. Applicable fluid temperature by -200 degrees C ~+560 C, the range of a variety of grades. Leakage standard has IV or VI level. The flow characteristic is linear or equal. Variety of specifications available for selection.
