MDSVP5600 series Intelligent valve positioner By the intelligent two-wire field instrument design and technology in the United States launched China, as an important supporting pneumatic valve control Parts are widely used in petroleum, chemical, electric power, metallurgy, light industry and other fields.
The electrical structure principle of 1 and MDSVP, to avoid the output of traditional positioner due to mechanical characteristics bring concussion, the zero drift of unstable performance weaknesses, makes the valve control More stable.2, the German original piezoelectric valve action time<20ms, high positioning accuracy, can be reduced due to inaccurate positioning of the valve opening shock, lifting valve control Precision.3, the valve characteristic curve and MDSVP correction process control Function can be extended range of application of the valve.4, MDSVP uses a special structural design, the formation of internal pressure in the microseismic cut off the external cavity of the gas permeability, and more adapt to the complex and harsh working conditions.5, MDSVP electric conversion unit with machinery, fully sealed structure, the German original piezoelectric valve average fault free switching frequency up to 2 billion times, high reliability.6, MDSVP with a flow adjusting device, can accurately through the base knob control Input to the implementation of air flow organization, so as to eliminate the oscillation of small capacity actuator.7, MDSVP comes with three valvestermination, without external electromagnetic valve, lock valve and other accessories can achieve the valve position switch or linkage switch output self regulating valve, to avoid failure and endanger production.8, MDSVP the latest U.S. electric conversion technology and the German original piezoelectric valve group, the steady-state air consumption of less than 36 liters per hour (conventional positioner for 400 l / h), a year can save more than 1400 electricity (the national standard of petrochemical energy consumption calculation).In 9, MDSVP in 1 minutes self-tuning zero and travel, on-site training without external signal source; large volume applications, can communication Download all operating parameters; only 3 buttons to complete.10, MDSVP with 7 double word LCD, rotating opening and optional pressure gauge display, clear and intuitive reaction of site conditions.Emergency mode, 11 unique to MDSVP, can not open the closed shell in the absence of direct manual operation valve.
