The OEM sales channel is projected to account for 60.00% of the Crank Case Ventilation Valve market revenue in 2025, making it the leading channel. This dominance is being driven by the preference for factory-fitted components that ensure reliability, adherence to manufacturer specifications, and long-term engine performance. OEM valves are favored due to their high quality, integration with engine management systems, and compliance with emission standards, which reduces maintenance costs and increases durability.
The growth of the OEM channel has been reinforced by automotive manufacturers focusing on providing complete and warranty-backed solutions to end customers. Moreover, the global expansion of vehicle production and the trend of offering pre-installed emission control components in new vehicles have strengthened the market share of OEM channels.
The adoption of OEM valves is further supported by increasing consumer awareness regarding engine efficiency and longevity, which encourages the use of original equipment With automotive production expected to rise, the OEM channel is anticipated to maintain leadership in the market due to consistent demand for reliable, factory-installed crank case ventilation solutions.
The Diesel Crank Case Ventilation Valve is expected to capture 55.00% of the market revenue in 2025, making it the leading fuel type segment. This prevalence is being attributed to the widespread use of diesel engines in commercial vehicles, heavy-duty trucks, and industrial applications where high torque and efficiency are required. Diesel engines produce higher levels of blow-by gases, necessitating advanced crank case ventilation solutions to prevent engine damage and reduce emissions.
The growth of this segment has been reinforced by stringent emission regulations that mandate precise control over particulate and hydrocarbon outputs. Additionally, diesel engine manufacturers are increasingly adopting valves designed to optimize airflow and improve engine longevity, which has accelerated demand.
The segment benefits from a stable installed base of diesel-powered vehicles in key markets and growing investment in emission-compliant diesel technologies As governments continue to enforce stricter diesel emission standards and operators focus on fleet efficiency, the diesel crank case ventilation valve segment is expected to sustain its leading position in the market.
The Fixed Crank Case Ventilation Valve is projected to hold 50.00% of the market revenue in 2025, positioning it as the dominant type. This leadership is being driven by the simplicity, reliability, and cost-effectiveness of fixed valves, which require minimal maintenance while providing consistent performance under varying engine conditions. Fixed valves are widely used across passenger and commercial vehicles due to their durability and ability to withstand high-temperature and high-pressure environments.
The segment’s growth has been supported by increasing production of engines that rely on standardized, proven components for emission control and engine protection. Moreover, fixed valves offer compatibility with a wide range of engine designs, reducing the need for customization and simplifying integration in OEM assembly lines.
The long-term stability and predictability of fixed valves have made them a preferred choice for manufacturers seeking dependable solutions without frequent replacements As engine efficiency and emission compliance continue to be key priorities, the fixed crank case ventilation valve segment is expected to maintain its market leadership.
Crank case ventilation is a system that helps to eliminate harmful vapors from engine and helps to prevent vapors from being ejected into the atmosphere. The crank case ventilation valve is operational as both a pollution control device and as well as crank case ventilation system.
Since 1960s, crank case ventilation valve have been standard equipment on all new cars. However, not every petrol engines have these valves. Sometimes, dragsters use scavenger system (device) and venturi tube in the exhaust to take out combust gases and sustain a small quantity of vacuum in the crank case to avoid oil leaks on the track.
Owing to the growing importance to safeguard the global environment, efficient crank case ventilation valves are increasingly critical to diesel engine OEMs (Original Equipment Manufacturers). In future, globally diesel engine emission guidelines will require manufacturers to continue to reduce total particulate emissions.
Recent emission regulations in some countries and market sectors cover total engine emissions that include both crank case and tailpipe. Since crank case emissions contributes up to twenty five percent of total emissions, control of this air contamination source is critical to safeguard the earth’s environment.
