Danfoss VF 2, VF 3 Data sheet

Data sheet

Seated valves (PN 16)

VF 2 - 2-way valve, flange
VF 3 - 3-way valve, flange

Description

VF 2 and VF 3 valves provide a quality, cost
effective solution for most water and chilled
applications.

The valves are designed to be combined with
following actuators:

• DN 15-50 with AMV(E) 335, AMV(E) 435 or AMV(E)
438 SU actuators.
With AMV(E) 25 (SU/SD) or AMV(E) 35
actuators (with adapter 0 65Z 0311)

• DN 65, 80 with AMV(E) 335 or AMV(E) 435 actuators.
With AMV(E) 56 actuator (with adapter
065Z0312)

• DN 100 with AMV(E) 55/56 or AMV(E) 65x
actuators

• DN 125, 150 with AMV(E) 55/56, AMV(E) 65x or
AMV(E) 85/86 actuators

• DN 200-300 with AME 685 or AME 855 actuators

Features:

• Soft sealing design DN15-80, 200-300

• Snap mechanical connection together with
AMV(E) 335, AMV(E) 435

• Dedicated 2 and 3-port valve

• Suitable for diverting applications (3-port)

Main data:

• DN 15-300

• kVS 0.63 -1350 m3/h

• PN 16

• Up to close A-AB

• Down to close A-AB (VF 3 DN 200-300)

• Temperature:

• Circulation water/glycolic water up to 50 %:
2 (–10*) … 130 °C (DN 15-100)
2 (–10*) … 200 °C (DN 125, 150)
2 (–10*) … 130 °C (DN 200-300)

* At temperature s from −10 °C up to +2 °C use stem heater

• Flange connections PN 16

• Compliance with Pressure Equipment
Directive 97/23/EC
