Product Overview

Huade® pressure reducing valves have always come up to the international standards. Huade Hydraulic make full use of abundant domestic resources to control costs in order to provide hydraulic products at a reasonable price. Pressure reducing Valve ZDR 6 DP0 can be used to reduce the pressure of hydraulic systems.

Key Features

  • Sandwich plate design

Industrial Applications

  • Valve type ZDR 6 DPO is used to reduce the system pressure.
  • Pressure reducing valves type ZDR 6 DPO...40B/40YM are pressure reducing valves of sandwich plate design. It basically valve consists of housing (1), the control spool (2), a compression spring seating (3) and a compression spring (4).
  • At rest, the valve is normally open, and fluid can flow unhindered from port P to port P1. The pressure in port P1 is at the same time present at the spool area opposite to the compression spring (4). When the pressure in port P1 exceeds the pressure level set at the
  • compression spring (4) the control spool(2) moves into the control position against the compression spring (4) and holds the set pressure in port P1 constant.
  • If the pressure in port P1 rises still further due to external forces, the control spool (2) is moved still further towards the compression spring (4).
  • Sufficient fluid then flows to tank to prevent any further rise in pressure. The spring chamber is always drained to tank externally via drilling to port T (Y).
