Vanne papillon à poignée rainurée D81X-16Q

Le Grooved Handle Butterfly Valve is manually operated via a handle, rotating the disc 0°-90° for on/off or flow control. With groove clamp installation (60% faster than flanges), it suits DN50-DN200 low-pressure water/HVAC systems, offering PN10-PN16 pressure and 0°C-80°C range.

DESCRIPTION DU PRODUIT

1.Manually pull the handle to directly drive the valve stem to rotate, causing the valve plate to rotate around the axis.
2.The valve plate is fully closed at 0° and fully open at 90°. The flow rate is adjusted at the middle angle.
3. The operating torque is greatly affected by the diameter and medium pressure, and is suitable for small diameter or low pressure scenes

CARACTÉRISTIQUES

1.Easy installation:Groove clamp connection, installation speed is more than 60% faster than flange type, especially suitable for renovation or emergency repair projects.
2.Low cost:Omits turbine transmission mechanism, simple structure, low manufacturing cost, and more competitive price.
3.Lightweight design:Usually suitable for DN50-DN200 small and medium-sized pipes, light weight, flexible operation.
4.Limitations:Effortless operation: large diameter (DN200 or above) or high pressure conditions require greater operating force, and auxiliary tools may be required.
5.No self-locking: Depends on manual positioning, easy to loosen in high vibration scenes.
6.Pressure resistance and temperature:The nominal pressure is generally PN10-PN16, and the applicable temperature range is: -0℃~80℃ (related to the sealing material).

CANDIDATURE

1.Low-pressure water supply and drainage system: water pipes and rainwater discharge inside buildings.
2.HVAC: small chilled water circulation, fan coil control.
3.Temporary pipeline: temporary water supply/drainage for construction that requires quick disassembly and assembly.
4.Space-constrained environment: The handle takes up little space and is suitable for installation in small areas.
