Imported Electric Bellows Control Valve
Import Electric Steam Regulating Valve, Bellows Sealed Regulating Valve, Bellows Regulating Valve Structure and Principle
1. Imported Electric Corrugated Pipe regulating valve Product Overview
Germany's VorwerkWODEOur imported electric corrugated tube regulating valve, by2SBSeries(OrPSLSeries)Electrical actuator and low flow resistance valve body assembly, electric actuator features an integrated structure with a servo amplifier, and input control signals(4-20mADCOr1-5VDC)The valve can be controlled to adjust the opening degree with power, achieving regulation of process parameters such as pressure, flow rate, liquid level, and temperature. The electric bellows regulating valve features an upper guidance structure, which is compact and efficient.SStreamlined channels with minimal pressure drop and high flow rates, wide adjustable range, and high precision flow characteristics. The electric bellows regulating valve features a bellows-sealed structure on the valve cover, suitable for the regulation of highly corrosive, flammable, explosive, volatile, and precious metal media. The electric bellows regulating valve is also applicable in vacuum conditions.
