目盛り付きボールバルブハンドル — 0～90°の手動流量制御

製品説明

A standard ball valve is built for all-or-nothing flow. Fit this 目盛り付きハンドル and it becomes a simple manual flow control ball valve: a scale plate marked from 0° to 90° in 10° increments sits under the handle, and a locking pin secures the handle at the notch you choose — 30°, 50°, or any other step.

For simple throttling jobs, this is a far cheaper route than an automated control valve — one 304 stainless steel accessory instead of an actuator, positioner, and wiring.

How the Locking Pin Works

• Set: turn the handle to the angle you need and secure the locking pin in the matching notch on the graduated plate.
• Hold: with the pin engaged, the handle resists pipeline vibration and flow-induced movement in normal service — changing the position takes a deliberate release of the pin.
• Repeat: operators can note a setting (“notch 3”) and return the valve to exactly the same flow after maintenance or flushing.

主な仕様

Ball Valve + Graduated Handle vs. Control Valve

This handle suits manual balancing: 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 — 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.

使用場所

• HVAC balancing — regulating hot and cold water flow to coils.
• Mixing lines — manually setting the ratio between two fluids.
• Process control — holding a constant flow rate for filling or cooling.

よくある質問

Can a ball valve really be used for flow control?

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 — this handle is the low-cost answer for set-and-hold applications.

What are the scale increments?

The plate is marked from 0° to 90° in 10° increments, so the valve locks at any of the ten positions.

どのバルブに対応していますか？

Our own ball valve series. The handle is made to match our valve stems, so we do not guarantee fit on other brands’ valves — include your valve model when ordering.

Is this the same as a memory stop?

It covers the same need and more. A memory stop limits the handle to one preset position; the graduated handle locks at any 10° step and lets you return to a recorded setting whenever you want.

Will vibration shift the valve position?

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.
