Electric Welded Butterfly Sanitary Valves
Butterfly Valve Introduction:
A butterfly valve is a mechanism that regulates the flow of materials within large pipe diameters by the quarter-turn rotation of a disc.
A rod feeds through the center of a disc and this rod is connected to an actuator that controls the motion of the disc. The disc position is either parallel or perpendicular to the flow of media. A butterfly valve differs from other valves because the disc is always in the flow causing a pressure change for any position of the valve.
Sound systems rely on dependable valves. Our butterfly control valve selection is made up of disc valves perfectly sized for various applications and made in precise accordance with industry standards.
1. Double axis butterfly valve designed to comply with MSS-SP-67, BS 5155 and API609. Compatible with GB, DIN, BS, ANSI125/150 flanges. Face to face according to ISO5752.
2. The seat of double axis butterfly valve is designed in to without back, the touque-and-groove seat is lower torque and replaceable.
3. There is O-ring casted on the seal surface of the seat, negates need for flange gaskets.
4. Available in wafer type and lug type.
5. Available with handles, manual gear operators and electric or pneumatic actuators.
Features：
1. Simple and compact construction, quick 90 degrees on-off operation. Mininmized operating torque, energy saving.
2. Bubbles-tight sealing with no leakage under the pressure test.
3. The connection of driven part conforms to ISO5211.
4. Wide selection of materials, applicable for various medium.
5. The valve body and disc are accurately machined which results in low operation torque and long service life and reliability.
6. Can be disassembled, material-specific recycling possible.
7.Can be installed at the end of pipe for lugged type butterfly valve.
Adavantages：
