Product Description
What is a Extension Stem Manual Butterfly Valve?
A Extension Stem Manual Butterfly Valve is a specialized rotary valve utilized for controlling flow within pipelines. It features a circular disk, often referred to as a “butterfly,” which rotates on its central axis to either open or close the flow pathway within the valve body.
Materials Used in Crafting Extension Stem Manual Butterfly Valve
- Body: Typically crafted from durable materials such as ductile iron, cast steel, or aluminum, ensuring resilience against pressurized systems and corrosion.
- Disk: Available in aluminum bronze, ductile iron, or nodular iron variants known for their corrosion-resistant properties and ability to provide effective shut-off capabilities.
- Seat: The sealing surface is composed of resilient materials like EPDM, NBR, or FFKM rubber, meticulously selected for temperature resilience, chemical compatibility, and extended lifespan.
Characteristics of Extension Stem Manual Butterfly Valve
- Body: Crafted from robust cast iron, steel, or stainless steel, the Extension Stem Manual Butterfly Valve body is engineered to endure system pressures effectively.
- Float: Housing a lightweight float connected to a linkage or mechanism, this component facilitates the automatic opening and closing of the Extension Stem Manual Butterfly Valve.
- Seat: Featuring a resilient synthetic rubber seal, the seat establishes a secure, leak-free barrier to prevent water loss.
- Applications: These valves play a crucial role in air removal during filling (air valves) and air release during draining (vacuum relief valves) operations.
- Operation: As the water level rises in the pipe, air within the rising main escapes through the air valve via Wholesale Extension Stem Manual Butterfly Valve Manufacturer. When draining, pressure fluctuations trigger vacuum valves to avert collapse.
Applications of Extension Stem Manual Butterfly Valve
- Water Supply – Ensures clean water is not contaminated by backflows from industrial plants, irrigation systems or buildings.
- Swimming Pools – Extension Stem Manual Butterfly Valve protects treated pool water and prevents drainage back-siphoning saltwater into fresh supplies.
- Process & Power Plants – Prevents reverse circulation in steam lines, cooling systems, pumps and critical fluid transfer processes.
- Medical & Laboratory – Backflow prevention safeguards sterilization systems and protects bio-samples in laboratories from contamination.
- Fire Protection – Extension Stem Manual Butterfly Valve checks flow direction in sprinkler systems to guarantee adequate pressure is maintained at each sprinkler head.
- Marine – Keeps ballast systems secure against reversing water currents or accidental suction intakes when loading cargo holds.
