  • Introduction
  • Specifications
ZAJW electric adjusting butterfly valve, a rotary adjusting valve, is the operation unit of pneumatic unit combination instrument. Valve body structure: soft sealing valve seat and full metal valve seat, separately used in normal（-40～180℃）and high temperature（-60～450℃） fields. Good sealing, large rated flow coefficient. Widely used in petroleum、chemical、pharmacy、metallurgy、textile、paper and sewage treatment departments. Nominal pressure: 1.6、4.0、6.4Mpa.
Nominal diameter: 25 to 200mm, input signal: 0-10mA.DC、4-2010mA.DC1-5V.DC, etc.
Allowed leakage: IV and VI. Using temperature: -60～450℃
