double throttle/check sandwich valves for mounting between the subplate and directional controlvalves type Z2FS
Throttle/check valve type Z2FS... is used to control main flow rate (or pilot flow rate) in one direction of flow and to allow free flow in the opposite direction. The valve is applied to vertical stack mounting (sandwich plate) - generally is fitted between subplate and directional valve of the same nominal size and in this case is used to limit main flow rate (to control the speed of a receiver movement). For directional valves pilot operated the valve is installed as a pilot choke adjuster (to limit pilot flow rate).
