High Performance Butterfly Valve

Features of High Performance Butterfly Valve

1. The resilient seat design offers an optimized solution for wear-out scenarios and requires low torque. It allows easy seat replacement without special tools.
2. Composite bearings on the stem above and below the disc, made of PTFE and epoxy filament winding, reduce torque during operation and minimize wear for extended service life.
3. The fireproof bi-directional resilient seat design ensures zero leakage during normal operation. Additionally, the metal-to-metal seal meets or exceeds industry fire safety standards.
4. The gland flange design applies load against the packing gland to prevent external leakage and is fully adjustable.
5. Equipped with an ISO 5211 top plate, enabling direct mounting of various actuators, handles, and gears.
6. The adjustable stem packing features a pull-down gland, allowing easy access without removing the actuator.
7. Tangential wedge pins are offset from the stem’s center, reducing stress and preventing potential seat damage.
8. The disc stop prevents unwanted disc rotation, further safeguarding the seat.
9. A retainer clip ensures the stem remains blow-out proof.
10. The live-loaded stem seal system, aided by Belleville springs, maintains pressure. A rocker-shaped gland bridge compensates for uneven gland bolt adjustment.
11. The “Bear-X” bearing offers excellent thermal, chemical, and wear resistance.
12. The valve’s one-piece body with an extended neck enhances durability.
13. Featuring a self-energizing flexible lip seal soft seat design with two points of contact on the fire-safe metal seat, ensuring reliability.

Relevant Information about High Performance Butterfly Valve

1. Rotor: The rotor in a High Performance Butterfly Valve is the disc that rotates within the valve body to control the flow of fluid. It is typically made of durable materials like stainless steel or ductile iron to ensure longevity and efficient operation.
2. Stator: The stator refers to the stationary part of the valve, which includes the valve body and seat. It provides the necessary support and sealing surface for the rotor to operate smoothly and effectively.
3. Universal Joint: The universal joint connects the actuator to the valve shaft, allowing for rotational movement. It ensures that the motion from the actuator is transferred accurately to the valve, enabling precise control of fluid flow.
4. Shaft Seal: The shaft seal prevents leakage along the valve shaft where it passes through the valve body. It is typically a robust sealing mechanism, such as a gland packing or mechanical seal, designed to withstand the pressures and temperatures of the operating environment.
5. Driving System: The driving system of a High Performance Butterfly Valve includes the actuator, which can be manual, pneumatic, or electric. The actuator provides the necessary force to operate the valve, either through manual adjustment or automated control systems, depending on the application requirements.
