Electric through two-seat regulating valve

A brief introduction:
ZAZN seriesThrough two seater electric regulating valveThe DDZ series of straight stroke electric actuator and valve seat is composed of two parts through.Based on the single-phase AC 220V power supply for power, take 0 ~ 10mA or 4-20mA DC signal, automatic control valve opening, continuous adjustment of the fluid in the pipeline pressure, flow, level and other parameters of the.The product is sensitive, convenient and energy characteristics of fast signal transmission.Application of fluid temperature in a variety of grades -250 to +560 DEG C range.Leakage standards for grade II or IV.Flow characteristics such as linear or percentage.A variety of different specifications can be selected.
Two, widely used:
ZAZN seriesThrough two seater electric regulating valveDual oriented structure, equipped with 9610L series electric actuators straight trip.Through two seater electric control valve has the advantages of compact structure, light weight, flexible action, valve capacity, accurate flow characteristics, convenient disassembly and assembly etc..Widely used in precise control of gas, liquid, steam and other media do process parameters such as pressure, flow, temperature, liquid level is maintained at a given value.Especially suitable for larger pressure difference, allowable leakage amount is large and not very clean medium occasions.
Three, the allowable error:
The standard group with electric through engine valve considering the erosion of media on the spool, the valve seat and the pressure difference caused by noise, vibration, under normal circumstances, the valve pressure difference should not exceed 1MPa, such as the pressure difference is high, should adopt corresponding technical measures.
Four, the material of main parts:
1, valve body, valve cover: HT200, ZG230 - 450, ZG1Cr18Ni9Ti;
2, valve, valve seat: 1Cr18Ni9Ti, our titanium Levin alloy surfacing;
3, packing: PTFE, graphite, stainless steel bellows;
4, pad: Poly rubber asbestos board, 1Cr18Ni9Ti, graphite spiral wound gasket;
5, valve rod, push rod: 2Cr13, 1Cr18Ni9Ti;
6, lining: 2Cr13.
Five, the main technical parameters:

Six, the main technical performance index:

Seven, the valve material and suitable temperature range:
