Product details

23QK-L15 (QY423) Two-Position Three-Way Normally Open Pneumatic Control Valve

normally open pneumatic control valve 23QK‑L15 is a 3/2‑way pilot‑operated normally‑open directional component, belonging to key Pneumatic Parts. It is widely matched with Power Pack Unit to perform airflow on‑off and direction switching for pneumatic control circuits. Installed on drilling rig, petroleum and mining industrial Machine, this air‑controlled valve outputs continuous air supply under normal status and cuts off airflow upon receiving pilot signal. It is suitable for new‑equipment assembly, pneumatic system upgrading and aftermarket replacement of worn Pneumatic Parts.
