• Valve body is designed to meet MSS SP-67 and API609.
• Upper flange standards: Valve mounting flange and stem shall be per ISO 5211.
• Flange Standard: GB 9113.1N ANSI 150 B16.5,JIS B2211.
• Pressure Rating:
• Bi-directional bubble-tight shut off to: 16 bar(230psi) DN40~DN600mm
• And tested to 110% of full rating: 18 bar(260psi) DN40~DN600mm
• Shell Testing:
• The body strength can stand 150% of full rating: 24 bar(340psi) DN40~DN600mm

Main Features

• Tight sealing and zero leakage under rated pressure(1 .OMpa,1.6Mpa).
• Multi-sealing design separates valve body from working media to ensure zero leakage.
• Main parts are designed to fit exactly into each other to ensure a better sealing, smaller torque, bigger flow, lower fluid resistance as well as flexible two-side flow.
• Scientific design for the sealing surface of valve seat makes a closed connection between the valve and the pipe flange without any additional ccessories.
• Designed and produced based on multi-standard system, so the valve could be applied to various of flange and enjoy excellent interchangability.
• All parts are embalmed, suitable for various complex work environment.
• Others: According to customer requirements.

A butterfly valve is a type of flow control device, typically used to regulate a fluid flowing through a section of pipe.
The valve is similar in operation to a ball valve. A flat circular plate is positioned in the center of the pipe.
The plate has a rod through it connected to an actuator on the outside of the valve. Rotating the actuator turns the
plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flow,
therefore a pressure drop is always induced in the flow regardless of valve position.
