Sandwich plate design Valves type Z 2 FS 16 are double throttle/check valves. The function of this valve is to control the inlet or outlet flow. The fact that Huade® Z 2 FS 16 can replace Rexroth® Z2FS 16 3XB is mainly due to the long-term cooperation with Rexroth. The factory strictly controls product quality and all throttle check valves meet international standards.

Features:
▶ Sandwich plate design
▶ Porting pattern to DIN 24 340, from A, ISO 4401 and CETOP - RP 121H
▶ Limiting of main or pilot flow with two service ports
▶ Meter-in or meter-out control.
Application:
Throttle check valves Z 2 FS 16 are used to limit main or pilot oil flow at one or two service ports.
Valves type Z 2 FS 16 are double throttle/check valves in sandwich plate design. Two symmetrically arranged throttle/check valves limit flow (by means of adjustable throttle spools) in one direction and permit free return flow in the other direction.
Main flow limiting
The double throttle/check valve is fitted between the directional valve and the subplate to change the speed of an actuator (main flow limiting).
Pilot flow limiting
In the case of pilot operated directional valves, the double throttle/check valve may be used as a pilot choke adjustment (pilot flow limiting). In this case, it is fitted between the main valve and the pilot valve.
