Pinless Concentric Stainless Steel Butterfly Valve With Backed Seat

Pinless Concentric MULTITOP Stainless Steel Butterfly Valve With Backed Seat

TKEO Resilient Seated Butterfly Valve, is also referred to as “concentric”,"rubber lined" and “rubber seated” butterfly valve, has a rubber (or resilient) seat between the external diameter of the disc and the internal wall of the valve.

Butterfly valve is a quarter-turn valve that rotates 90 degrees to open or close the media flow. It has a circular disc, also known as the butterfly, found at the center of the body that functions as the closing mechanism of the valve. The disc is connected to an actuator or handle through the shaft, which goes through from the disc to the top of the valve body.

The movement of the disc will determine the position of the butterfly valve. The resilient seated butterfly valve lug type can work as isolating valve if the disc rotates a full 90-degree turn, the valve is completely opened or closed.

Butterfly valve is also used as flow regulating valve, if the disc does not rotate to a full quarter-turn, it means the valve is partially open, we can regulate the flow of fluids by various open angle.

Main Features

• Compact construction results in low weight, less space in storage and installation.
• Centric shaft position,100% bi-directional bubble tightness, which makes installation acceptable at any direction.
• Full bore body gives low resistance to flow.
• No cavities in the flow passage, which makes it easy to clean and disinfect for potable water system etc.
• Rubber lined internally in the body makes fluid not to contact the body.
• Pinless disc design is helpful to prevent the leakage point on the disc.
• ISO 5211 top flange is convenient for easy automation and retrofitting of actuator.
• Low operating torques results in easy operation and economical actuator selection.
• PTFE lined bearings are designed for anti-friction and wear, no lubrication is required.
• Inserted lining to the body, liner easy to replace, no corrosion between body and lining, suitable for end of line use.
