2-2 way descaling valves insert XY controlled DN50 DN125 PN420

  • Operating pressure: 420bar
  • Nominal size(s): DN80, 100
  • Ways: 2/2

Features

  • Hydraulically actuated directional seat valve controlling liquid media
  • Passively controllable 2/2-way valve with 1-stage control logic
  • Valve seat sleeve equipped with a low-friction seal
  • Valve piston and seat are coupled and close hydraulically „leak-free“
  • The valve is actuated via a 3/2-way pilot valve
  • The switching position can optionally monitored by a proximity switch for open and close position
  • Installation space according Hauhinco standard

Function 2/2-way valve insert

The valve piston (2) guided within the Valve seat sleeve (1) is pressed into the valve seat (3) by the hydraulic power and the spring force generated by the control pressure (X) on the control surface (5). Thus, the lines (A, B) are separated.

By switching the pilot valve (4), the control surface (5) is depressurised and the hydraulic power along the lines (A, B) can be used to lift the valve piston (2) o the valve seat (3), i.e. as soon as the hydraulic pressure is applied to the lines (A, B), the valve piston (2) moves into the opened position up to the mechanical end position. Thus, the lines (A, B) are connected. The ring-surface (6) of the valve piston (2) must be connected to the leakage line (Y) of the manifold.
