A standard ball valve is built for all-or-nothing flow. Fit this \u76ee\u76db\u308a\u4ed8\u304d\u30cf\u30f3\u30c9\u30eb<\/strong> and it becomes a simple manual flow control ball valve<\/strong>: a scale plate marked from 0\u00b0 to 90\u00b0 in 10\u00b0 increments sits under the handle, and a locking pin secures the handle at the notch you choose \u2014 30\u00b0, 50\u00b0, or any other step.<\/p>\n For simple throttling jobs, this is a far cheaper route than an automated control valve \u2014 one 304 stainless steel accessory instead of an actuator, positioner, and wiring.<\/p>\n This handle suits manual balancing<\/strong>: jobs where someone sets a flow rate once and the system holds it. If your process needs continuous automatic adjustment, that is control-valve territory \u2014 but for filling, cooling, or mixing lines that just need a repeatable setting, the graduated handle does the job at a fraction of the cost.<\/p>\n For simple manual throttling, yes. The graduated plate lets you set a partial opening and secure it with the locking pin. For processes that need continuous, automatic adjustment, use a dedicated control valve \u2014 this handle is the low-cost answer for set-and-hold applications.<\/p>\n The plate is marked from 0\u00b0 to 90\u00b0 in 10\u00b0 increments, so the valve locks at any of the ten positions.<\/p>\n Our own ball valve series. The handle is made to match our valve stems, so we do not guarantee fit on other brands’ valves \u2014 include your valve model when ordering.<\/p>\n It covers the same need and more. A memory stop limits the handle to one preset position; the graduated handle locks at any 10\u00b0 step and lets you return to a recorded setting whenever you want.<\/p>\n The locking pin secures the handle in the plate notch, so the setting resists pipeline vibration and flow pressure in normal service. Changing the position takes a deliberate release of the pin by the operator.<\/p>\n Send us the quantity and the valve model the handle is for. We reply to every inquiry within 24 hours.<\/p>\nHow the Locking Pin Works<\/h2>\n
