Overview
The ZRHP/M-BWG electric bellows regulating valve consists of a 3810 series (PSL series) electronic electric actuator and a low flow resistance regulating valve body. The electric actuator is an integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature.
Product Details
The valve core of the electric bellows sealed regulating valve adopts an upward guide structure, which is compact in structure and has an S-shaped flow channel, which reduces pressure drop loss, increases flow rate, has a wide adjustable range, and high accuracy of flow characteristics, in compliance with the IEC534-1-1976 standard. The upper valve cover adopts a corrugated pipe sealing structure,Electric bellows regulating valveSuitable for regulating highly sensitive, flammable, explosive, volatile, and rare precious metal media. in additionElectric bellows regulating valveIt can also be used in vacuum situations.
