Ross Controls 3126A4007 Manual Hand Valve 4 Way

Ross Controls 3126A4007 is a heavy‑duty manual horizontal hand‑lever valve from the 31 Series, a 4/3 directional valve with open‑center configuration and detented operation. It uses 1/2"–3/4" NPT ports for inlet, outlet, and tank connections, making it suitable for hydraulic circuits that require four ports and three positions. The valve is detented, providing positive stops at each of its three thumb‑actuated positions for repeatable operation, and its flow characteristics are Cv 2.8 (open center) and 2.3 (closed center). For BSPP (G) threaded variants, the prefix D is used (e.g., D3126A4007) to designate the corresponding configuration.
