Composite Exhaust Valve Carbon Fiber Ceramic Matrix for Automotive Aerospace Marine and Industrial Applications

Composite Exhaust valve

Composite exhaust valve is an automatic exhaust device used in pipeline systems, which has both fast exhaust and micro exhaust functions. Its core feature is to efficiently exhaust the air in the pipeline through a dual valve structure (large exhaust port and small exhaust port) to prevent air blockage; At the same time, it can automatically shut down to prevent liquid leakage. Mainly used in HVAC, water supply and drainage systems, it has the advantages of compact structure, high pressure resistance, and automatic opening and closing.

Low maintenance cost
Excellent sealing performance
Corrosion resistance and long lifespan
Efficient automatic exhaust
Simple and reliable structure

Low maintenance cost

01
Online maintenance capability
Disassembling the valve core or float ball does not require dismantling the valve body, greatly reducing maintenance time.
02
Standardized components
The snap in structure facilitates the replacement of worn parts and reduces operational complexity.

Excellent sealing performance

01
Dynamic sealing mechanism
The spring supports the sealing end face, adapts to the movement of the lever, and has extremely low leakage in the closed state.
02
Double leak proof design
After exhaust, the floating ball rises and tightly seals the exhaust port to prevent medium backflow.

Corrosion resistance and long lifespan

01
Strong weather resistance of materials
The valve body is made of stainless steel (304/316), cast iron and other materials, which are resistant to corrosive media and high temperatures (-200 ℃~110 ℃).
02
Key component optimization
The float is made of low-density PP material that is resistant to high temperatures and does not deform. The valve stem is made of hard plastic that is rust resistant, ensuring long-term stable operation.

Efficient automatic exhaust

01
Quick response to gas accumulation
The float/lever mechanism is sensitive and automatically opens the exhaust port when the gas pressure rises, quickly eliminating the air inside the pipeline.
02
Negative pressure protection function
When negative pressure is generated in the pipeline, it automatically sucks in air to prevent deformation or rupture of the pipeline.

Simple and reliable structure

01
Compact integrated design
The single port structure reduces the number of components, lowers the risk of failure, and facilitates maintenance.
Flexible installation
02
The internal thread or flange connection is compatible with various pipeline layouts, and can be quickly installed without the need for complex tools.
