Butterfly valve with electrical actuator VFY-WA

Transcription

1 Butterfly valve with electrical actuator Description Position indicator Torque limiter Complete installation from factory - ready for installation Features: Spline driven one piece shaft connected to spherically machined disc allows high torque transmission i.e. quick response and minimum back-lash Long term reliability due to upper and lower anti-friction bearings Safe maintenance: shaft blow out protection with circlip Manual operation Main Data: k VS m 3 /h PN 16 (10) EPDM Liner Stainless steel or Polyamid coated disc Medium: - Circulation water, drinking water or chilled glycolic water up to 50 % Medium temperature: C (PA disc) C (SS disc) Nominal voltage: - 24 V; 50 Hz/60 Hz V; 50 Hz/60 Hz Control input signal: On/Off or 3-point Torque: Nm Grade of enclosure: IP66/68 Ambient temperature: C Duty rating IEC34: cycle S4 (50 % ) Approvals: Ordering Type 230 V Picture k VS (m 3 /h) PN T max Opening time ( C) (s) Disc Code No. 082G / G G G G Stainless 082G Steel 082G G G G G G Polyamid 082G Coating 082G G G G G G G G G7375 Danfoss VD.HD.T8.02 1

5 Installation positions Recommended Possible Possible Not recommended Installation conditions It is recommended that distances indicated below are respected in order to prolong lifetime of the valve. Mounting the valve close to pipework junctions (turbulent zones) increases wear VD.HD.T8.02 Danfoss
