BZRHP/M Electric Explosion-Proof Control Valve

The BZRHP/M electric explosion-proof control valve is suitable for most applications in process control technology. It is particularly well-suited for demanding operational conditions due to its wide adjustment range, selectable valve plug surfaces, and high shut-off tightness. This explosion-proof electric control valve is a top-guided type, paired with the 3810 series electronic electric actuator. The electric actuator incorporates a servo amplifier, eliminating the need for an external servo amplifier. It requires only an input control signal (4-20mADC or 1-5VDC) and single-phase power supply to operate, enabling regulation of parameters such as pressure, flow rate, temperature, and liquid level.
