Triple Offset Butterfly Valve

A triple offset butterfly valve is a type of butterfly valve that is designed to provide a reliable and tight sealing performance even in high-temperature and high-pressure applications.The triple offset design of the valve ensures that the seal ring is constantly in contact with the sealing surface throughout the entire range of travel, providing a bubble-tight seal. This design also reduces friction between the seal ring and the sealing surface, resulting in a longer service life and better operating efficiency.Triple offset butterfly valves are commonly used in industries such as oil and gas, power generation, chemical processing, and pulp and paper. They are particularly popular for applications that require bi-directional shut-off capabilities or for handling abrasive, corrosive, or high-temperature fluids.At Supcon, we offer a wide range of triple offset butterfly valves to meet the needs of various applications. Our valves are manufactured to stringent quality standards, ensuring exceptional performance and reliability.

Electric Triple Offset Butterfly Valve
The electric triple eccentric butterfly valve adopts a three-dimensional eccentric structure, and has the advantages of strong applicability, small torque force, less friction, and good sealing performance. When the electric triple eccentric butterfly valve is opened, the disc will instantly separates the sealing surface of the seat, which reduces friction and interference with the sealing surface, and greatly improves the service life of the butterfly valve. Moreover, the electric triple eccentric butterfly valve disc and the seat sealing surface are made of stainless steel, so that the butterfly valve has reliable guarantee of corrosion resistance, temperature resistance, pressure resistance and wear resistance, and is a high-performance energy-saving electric butterfly valve.

China Butterfly Valve
A butterfly valve is a type of quarter-turn valve that is used to control the flow of a fluid through a pipe. It consists of a circular disc or vane with a pivot in the center. When the valve is fully open, the disc is turned parallel to the direction of flow, allowing the fluid to pass through with little resistance. When the valve is closed, the disc is turned perpendicular to the direction of flow, blocking the flow of fluid.

Butterfly valves are often used in applications where the flow of a fluid needs to be controlled quickly and easily, such as in HVAC systems, water treatment plants, and fire protection systems. They are typically less expensive and lighter in weight than other types of valves, making them easier to install and maintain. They can also be operated manually or automatically using a motor or actuator.

Rotary Plug Valve
A rotary plug valve with a plug-shaped flow-restricting component that follows an eccentric path as it rotates. The plug does not contact its seat until it is rotated to within a few degrees of the closed position. When the plug contacts or "cams" into the seat, the seat surfaces are dynamically aligned for closure. This rotary plug valve type may also be referred to as a rotary globe valve.

How rotary plug valve work:
When the material in the upper bunker falls under its own weight and fills the space in the rotor blade, it rotates with the blade to the lower outlet and is discharged. Rotary plug valve can continuously supply and discharge materials. The rotary plug valve can play the role of feeding and locking the air flow in the pneumatic conveying system. Due to the low-speed rotation of the rotor and the very small gap between the rotor and the inner cavity of the housing, the reverse flow of the air flow is effectively prevented, thereby ensuring the stability of the air pressure in the system and the normal discharge of materials. Therefor, rotary plug valve is an important part of the high-pressure gas to the material transportation in the state of the pipe network. The rotary valve is used as the unloader of the silo in the material collection system.

V Notch Ball Valves
Our V-Ball, V-Port and v notch ball valves are made of high-quality materials. v notch ball valve, the "V" notch is a unique design that allows for precise flow and the ability to regulate and control flow through a 30�°, 60�° or 90�° V "notch". The v notch ball control valve is a low-maintenance valve with a tight bubble shut-off function. All v notch ball valves are highly manageable and can operate at high temperatures (up to 1000�°F) and pressures up to 500PSI (liquid) and 150PSI steam. V notch ball valves are cost-effective compared to valves with similar pressure drops and low flow control (down to 0.07) Cv. The v notch ball control valve is cost effective compared to valves with similar pressure drop and low flow control (down to 0.07). Our v notch ball valves can be manually configured or actuated for automated handling and control. These valves are available in ANSI flange, NTP (threaded) and socket weld.

V Notch Ball Valves introduction:
VN6 series V-notch ball valve, is concentric segmental ball valve for modulating applications. Its V-notch segmented ball permits wide range ability and produces an equal percentage flow characteristic. As the V-notch ball rotates into the seat ring, it creates a wedging and shearing effect to prevent dragging or slurries between the seat and the ball.Our v-notch ball valves normal size is 1" to 12".

V Notch Ball Valves Advantage:
The v-notch ball valves are used settled and also clamped driven shaft plus sphere shaft with splined connection made for absolutely no shed motion for very accurate placing and specific control.

The V-- Notch Sphere Valve gives non-clogging, high capability, straight with circulation control of fluids including pulp as well as paper stock or slurries and also fluids containing suspended solids or fibrous materials.

The V-shaped gap and the valve seat produce a tapered scissors function, which not only has a self-cleaning function but also prevents the ball core from being stuck, and is particularly suitable for pipeline scaling and freezing.

The v-notch ball valves have quality erosion-resistant trim components, such as Valve Positioners - Pneumatic, Electro-Pneumatic, Smart Instruments - Airset, Solenoid Valve, Volume Booster, Airlock, Limit Switches.

Pneumatic V-notch ball valves are perfect for maintaining flow in continuous or batch operations, controlling pressure in liquid fill lines and venting heat exchangers with vapour feed lines.

V notch ball control valve design features
The shearing action between the ball and the seal of the v notch ball control valve ensures tight closure, even on fibrous slurries.
