Product Overview

Double throttle/check valve type Z2FS 10…-30B/…is in sandwich plate design.  This flow valve is used for meter-in or meter-out control. It can replace the series Z2FS 10-5-3X offered by Rexroth due to two long-term cooperation with Rexroth. Product packaging of throttle valves Z2FS 10-5 can also be customized, such as plastic waterproof packaging, standard carton, or plywood packaging.

Maximum permissible degree of contamination of the hydraulic fluid to NAS 1638 class 9. We therefore recommend a filter with a minimum retention rate of B10  ≥75

Key Features

  • Sandwich plate valve
  • Porting pattern to DIN 24 340 from A, ISO 4401 and CETOP - RP 121 H
  • For limiting the main or pilot fluid flow of 2 service ports
  • 3 adjustment elements
  • Lockable rotary knob with scale
  • Spindle with internal hexagon and scale
  • Rotary knob with scale
  • For meter-in or meter-out control

Industrial Applications

  • Double throttle check valve Z2FS 10-5 is used to limit the main or pilot flow of one or two service ports.Two symmetrically arranged throttle/check valves limit the flow in one direction and allow free-flow in the opposite direction.
  • For meter-in control fluid passes from port A1 to port A2 via the throttling point (1), which is made up to the valve seat (2) and the throttling spool(3.1). The throttling spool (3.1) is axially adjustable via the spindle (4), thus allowing the throttling point (1) to be adjusted.At the same time the fluid in port A1 reaches spool side (6) via bore(5).The pressure present in addition to the spring force holds the throttle spool (3.1) in its throttling position.Flow flowing back from the service port B2 moves the throttle spool(3.2) against the spring (7) causing the valve to act as a check valve and allowing free-flow. Depending upon the way in which the valve is installed, the throttling effect can be arranged as a meter-in or meter-out control.
  • Limiting the main fluid flow
  • In order to change the velocity of an actuator (main fluid flow), the double throttle/check valve is installed between the directional valve and the sub-plate.
  • Limiting the pilot fluid flow
  • In pilot operated directional control valves, the double/throttle check valve is installed as a pilot choke adjustment (pilot fluid flow). It is fitted between the main valve and the pilot valve.
