I. Introduction ZXM series of pneumatic diaphragm straight-through regulating valves are the medium-pressure balancing regulating valves, which use sleeve guiding, double sealing surface spool structure for pressure balance and multi-spring actuator. The flow passage takes S-shape streamline, featuring stable operation, permitting large pressure difference, accurate flow characteristic, and low noise, etc. Therefore, the products are especially applied to working conditions that flow is large, valve has large pressure difference and leakage demand is not strict. These series products boast various models as standard type, heat sink type, low temperature type, adjusting/cutting off type and sylphon sealed type, etc. The nominal pressure grade (PN) is divided into 1.6, 4.0, 6.4, and 10.0 (MPA). The valve body caliber ranges from 20 mm to 200 mm. They are applied to liquid temperature ranging from -196°C to +560°C. The leakage grade is divided into IV, V and VI. The flow characteristics include straight line and percent. We provide you with various types and specifications. II. Features The structure of pneumatic diaphragm straight-through regulating valves: The regulating valve is generally composed of electric or pneumatic actuator and valve body. The linear motion mainly includes straight-through single seat and straight-through double seat. The double seat features good flow capacity, low imbalance and stable operation, which enable it be applied to conditions of large flow, great pressure drop and low leakage.
