DF series square gate valve
Application
DF series square gate valve is a kind of pneumatic shut-off valve used in the production process of pulping, mud, slag discharge and sewage treatment. It is especially suitable for high concentration slag remover in paper production, heavy material separator, hydraulic pulper and other equipment for slag discharge.
Feature
1. The flow resistance is small, and direct current is formed with the pipe when the gate disc is fully opened.
2. The valve body adopts a two-piece structure with no cavity in the body and is not easy to accumulate.
3. Good sealing, smooth movement, no vibration, and no noise.
4. The sealing seat is designed for the movable structure and has anti-wear and automatic compensation functions, so the service life is long.5. The sealing seat is made of metal seal and EPDM, PTFE soft seal structure, which can be applied to various working conditions.
