Metal Seated Wafer Butterfly Valve Compact Wafer‑Style Hard‑Seal Pipeline Butterfly Valve
- Metal Seated Wafer Butterfly Valve is compact hard‑seal butterfly valve adopting wafer clamping installation for harsh industrial pipeline conditions.
‑ Wafer body structure, compact dimension, save installation space
‑ Metal‑to‑metal hard‑seat design, stable sealing under high temperature
‑ Strong resistance to abrasive particle erosion and flue gas wear
‑ Simple clamping mounting between two pipeline flanges
‑ Multiple body material: carbon steel, stainless steel optional
‑ Support manual, pneumatic, electric and hydraulic drive
‑ Light‑weight structure, convenient for transportation and installation
‑ Reliable switching performance for frequent operation
‑ Strict hydrostatic shell and seat sealing test before shipment
‑ Support OEM, ODM for special temperature and pressure customization
‑ Complete test reports and technical documentation supplied
‑ Factory direct supply for energy, metallurgy and chemical engineering orders
Applications
Mainly applied in power plant, metallurgy, cement, waste incineration and chemical industry. Suitable for high‑temperature flue gas, dust‑containing gas, steam and abrasive medium pipeline for cut‑off and throttling regulation.
Working Principle
Metal Seated Wafer Butterfly Valve realizes opening and closing through 90‑degree rotation of butterfly disc. Disc parallel with pipeline enables medium flow; rotate 90°, disc compresses metal seat to block flow channel and achieve hard‑seal shut‑off. Wafer type is clamped between pipe flanges without extra flange connection, realizing compact installation.
