ZRHP/M-BWG Electric Bellows-Sealed Control Valve consists of a 3810 Series (PSL Series) electronic electric actuator and a low-flow-resistance control valve body. The electric actuator features an integrated structure with a built-in servo amplifier. Inputting control signals (4-20mADC or 1-5VDC) and power supply enables precise valve opening control, achieving regulation of process parameters such as pressure, flow rate, liquid level, and temperature. The valve plug employs an upper-guided structure with a compact design and an S-shaped streamlined flow passage. This configuration minimizes pressure drop, maximizes flow capacity, offers a wide adjustable range, and ensures high flow characteristic accuracy, conforming to IEC 534-1-1976 standards. The upper bonnet employs a bellows seal structure, making the electric bellows-sealed control valve suitable for regulating highly corrosive, flammable, explosive, volatile, and rare/precious metal media. Additionally, this valve can be used
