Single Opening Exhaust Valve for Tank Pipeline Pressure Vessel HVAC and Industrial Systems Suppliers and Manufacturers

Single Opening Exhaust Valves

Simple structure: single port design reduces components and is easy to maintain;

Efficient exhaust: The float/lever mechanism is sensitive and quickly eliminates air from the pipeline;

Reliable sealing: automatic shut-off to prevent reverse flow of the medium, low leakage rate;

Corrosion resistance: Stainless steel/PP material is suitable for high temperature and corrosive environments;

Negative pressure protection: automatic air supply to prevent pipeline deformation.

Mainly used for the discharge of accumulated gas in heating, water supply and other pipeline systems.

Maintain convenience

Maintain convenience
01
Support online maintenance (such as disassembling the valve core without emptying the system), and equipped with an online detection mechanism for quick fault diagnosis.

Strong adaptability to pressure

Strong adaptability to pressure
01
The air shut-off pressure shall not be less than 0.1 MPa, and the full bore streamline flow channel design ensures stable operation under high and low pressure conditions.

Weather resistance and protection

Weather resistance and protection
01
The valve body material (such as stainless steel, cast iron) and overall encapsulation treatment are suitable for high temperatures (-200 ℃~110 ℃), high pressures, and corrosive media, and have anti freezing cracking characteristics, suitable for cold regions.

Simple and reliable structure

Simple and reliable structure
01
The free floating ball design has fewer components (such as valve core and floating ball), low failure rate, strong vibration resistance, and easy maintenance.

Excellent sealing performance

Excellent sealing performance
01
Adopting a sealing structure that combines soft and hard sealing, combined with the principle of self sealing, to achieve zero leakage sealing throughout the entire stage from low pressure (0.02 MPa) to nominal pressure range.

Automated response mechanism

Automated response mechanism
01
Based on the principles of pressure difference and buoyancy, it automatically opens and closes without manual intervention, responds sensitively, and reduces operation and maintenance costs.

Efficient exhaust performance

Efficient exhaust performance
01
The combination design of large exhaust valves and micro exhaust valves achieves high-speed exhaust (rapid gas removal during water filling), continuous micro exhaust (processing micro air during operation), and rapid suction (preventing negative pressure hazards when the pump is stopped), effectively preventing gas resistance, cavitation, and erosion phenomena.

Multi functional integrated structure

Multi functional integrated structure
01
Integrated with exhaust, check and filtration functions, reducing the number of valves required for the system and simplifying the overall design.
