Product Description
Product Description
I. Basic Definition & Structure
This valve belongs to the soft-seated butterfly valve family. It uses a disc (closure element) that rotates 0°-90° to open/close or regulate fluid flow in pipelines. Designed with a wafer-type connection (the valve body is clamped between pipeline flanges via bolts at both ends), it is manually actuated by a lever.
Key Components:
- Body: Valve body (typically ductile iron QT450, carbon steel WCB, or stainless steel CF8/CF8M/CF3M, etc.); Disc (ductile iron/stainless steel, sometimes with a frame structure or double-eccentric design); Valve stem.
- Sealing Components: Seat seals (commonly EPDM rubber, PTFE (Polytetrafluoroethylene), or other soft materials for reliable sealing).
- Actuation: Manual lever (electric/pneumatic actuation available for custom orders).
II. Core Performance Parameters
(Typical ranges-varies by manufacturer/custom requirements)
| Item | Specification |
|---|
| Product Model | D71X, D71F, D71X-16Q/C/P, etc. (subdivided by pressure rating & material) |
| Valve Body Material | Ductile Iron (QT450), Carbon Steel (WCB), Stainless Steel (CF8/CF8M/CF3M, etc.) |
| Connection Type | Wafer-type (clamped between pipeline flanges) |
| Nominal Diameter | DN40 ~ DN2000 (covers small to extra-large pipeline sizes) |
| Actuation Method | Manual (lever-operated; electric/pneumatic optional for customization) |
| Applicable Media | Water, gas, oil, sewage, steam, natural gas, and other general fluids |
| Temperature Range | -20ºC ~ 120ºC (adjustable via seal material-e.g., PTFE suits higher temps) |
| Nominal Pressure | 1.0MPa ~ 1.6MPa (custom orders may cover 0.6MPa ~ 2.5MPa) |
| Design/Standards | GB/T 12238-2008, ISO 10631, API 598, etc. |
III. Product Features
Structural & Operational Advantages:
- Compact, lightweight design with fast opening/closing (90° rotation). The lever requires minimal operating torque (easy to use) and allows installation in any orientation (no restrictions from fluid direction or space).
- Wafer-type connection eliminates the need for extra flanges, enabling quick installation/maintenance (easy to disassemble without interrupting the entire pipeline).
Sealing Performance:
- Soft-sealed structure (rubber/PTFE seals) ensures excellent leakage prevention (near-zero leakage in gas tests, suitable for bidirectional sealing). Seal materials resist aging and mild corrosion for a long service life.
Functionality & Adaptability:
- Combines on/off and flow regulation (linear flow characteristics for precise control). No debris retention, and low flow resistance (full-open position maximizes flow area).
- Customizable with different body, disc, and seal materials to suit media (e.g., stainless steel + PTFE for aggressive chemicals).
IV. Application Scenarios
Widely used in water supply/drainage, industrial fluid control, and municipal environmental projects. Typical uses:
- Water treatment plants (drinking water/sewage systems).
- Food, pharmaceutical, chemical, oil & gas, heating, and other industries (pipeline shutoff/flow control).
- Marine, hydropower, metallurgy, textile, etc. (cooling water, steam, oil pipelines).
V. Selection & Usage Notes
Selection Key Points:
- Choose body/seal materials based on media properties (corrosiveness, temperature, viscosity-e.g., ductile iron + EPDM for sewage; stainless steel + PTFE for strong chemicals).
- Match pipeline size and pressure (nominal diameter/pressure must align with the system).
- Consider actuation needs (manual/electric/pneumatic; smart control for automation).
Installation & Operation:
- Inspect seal integrity and clean the valve body before installation.
- Avoid over-torquing (prevents seal/stem damage). Regularly check seal performance and lever smoothness.
- Follow design standards (e.g., GB/T 13927 for pressure tests; GB/T 12221 for structure length).
