Description

Basic Info of High Performance Butterfly Valve

The main features of the eccentric wafer CF8 high-performance butterfly valve include:

HP butterfly valve is the unique butterfly valve type to regulate and modulate operations for applications like water systems and irrigation.
HP butterfly valve is Available in materials like CF8 CF8m, ensuring longevity and resistance to corrosion or negative pressure.
high performance butterfly valve eatures seals such as RPTFE, or PTFE, suitable for temperatures ranging from -20°C to 120°C, depending on the seal, and compatible with various media.
TOP FLANGE Supports standardized mounting (e.g., ISO 5211 F05), allowing integration with manual levers, gearboxes, or actuators for automated systems.
Wafer-style flange mounting fits between PN10/PN16 flanges, ideal for space-constrained installations and not requiring end-of-line use.
ISO 5211 F05: Typically used for smaller valves, with a square drive shaft of 11mm x 11mm, a PCD (pitch circle diameter) of 70mm, and 4 bolts of M6. It supports valves with lower torque requirements.

Advantage and Limitation of CF8 HP Butterfly Valve

Advantages of SS HP butterfly valve

Double eccentric design provides tight shut-off, reduced seat wear, and good throttling characteristics.
Low operating torque.
Suitable for space-constrained installations (not suitable for line terminations).

Limitations of RPTFE Seat HP butterfly valve:

RPTFE seats limit the temperature to approximately 120°C (not suitable for high-temperature steam or hot gases).
Unless otherwise stated, wafer valves are not recommended for dead-end applications.

Manufacture Process of Butterfly Valve

Application of SS HP Butterfly Valve

Water Supply and Irrigation — Ideal for regulating flow rates in water distribution, water treatment, and agricultural irrigation.

General Industrial Fluid Handling — Compatible with a wide range of media due to the RPTFE seat and optional stainless steel wetting parts.

HVAC, Heating and Cooling Systems — Commonly used in hot and cold water circuits.

Chemical and Corrosive Media Applications (when stainless steel valve disc/body is selected) — Suitable for acids, alkalis, solvents, and other chemicals over a wide temperature range (RPTFE has broad chemical compatibility).

Petrochemical and Refining (Utilities, Non-Extreme Conditions)

Pulp and Paper Manufacturing

Power Generation (Cooling Water, Auxiliary Systems)

Food and Beverage/Pharmaceutical (Appropriate materials required)

Wastewater Treatment
