FD01-BV1DF-3L(Double flanged Butterfly Valve–Handle Operation)
●Brief
When the flange butterfly valve is in the fully open position, the thickness of butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has good flow control characteristics. Butterfly valve has elastic seal and metal seal. Elastic sealing valve, sealing ring can be inlaid on the valve body or attached to the periphery of butterfly plate.
●Features
1. Butterfly plate can be sprayed with coating according to user's requirements, such as nylon or PTFE.
2. The valve can be designed as flange connection and clamp connection.
3. The driving mode can be manual, electric or pneumatic.
APPLICATION
General Use: Water,sea water,gas, pressurized air, acids etc.
