SHUANGLIN VALVE | Brass Regulating Valve with Numbered Dial, DN15–DN50

Balancing a multi-branch heating or water system means setting each valve to a specific position and being able to find that exact position again later. SHUANGLIN VALVE's regulating valve makes this straightforward with a numbered dial printed directly on the adjustment cap, turning what could be a guessing game into a simple, repeatable reference point.

A Number You Can Return To

The red cap is marked with a scale from 0 to 5, aligned against a fixed reference line on the valve body below. As the internal orifice is adjusted, the dial rotates to show exactly where the setting currently sits — whether fully closed at 0 or progressively more open toward 5. This matters most during commissioning, when a technician needs to record each valve's setting for future reference, and again during any later maintenance, when restoring a valve to its documented position should take seconds rather than requiring recalibration from scratch.

Straightforward Preset Flow Control

Like other lockshield-type regulating valves, this design is intended to be set once for normal balancing purposes rather than adjusted routinely — the numbered scale exists to support accurate, repeatable commissioning rather than everyday operation. The body carries a flow direction arrow for correct installation, and SHUANGLIN VALVE manufactures this valve in solid brass across the DN15 to DN50 size range, suitable for heating, chilled water, and general hydronic balancing.

Where It's Used

• Radiator and underfloor heating branch balancing

• Multi-zone chilled water and heating system commissioning

• Retrofit balancing work where documented, repeatable settings are needed

• General hydronic systems requiring visible flow presetting rather than continuous adjustment

Frequently Asked Questions

What does the numbered dial actually control? The dial reflects the position of an internal adjustable orifice that restricts flow through the valve. Higher numbers generally correspond to a more open setting, allowing more flow, while lower numbers restrict flow further.

Should this valve be adjusted frequently during normal use? No, it's designed to be set during system commissioning or balancing and left in that position for normal operation. Frequent adjustment isn't necessary and can make it harder to maintain a balanced system overall.

What if I need this setting protected from being changed by others? For installations where the setting needs to be secured against tampering, SHUANGLIN VALVE also offers a magnetic locking regulating valve, which conceals the adjustment mechanism behind a sealed magnetic lock cap instead of a visible dial.
