Product Description An exhaust valve is a device used to remove gas from a pipeline or closed system. It is mainly used to prevent air blockage (air accumulation affects fluid flow), improve system efficiency or avoid equipment damage. The following is a detailed introduction to the exhaust valve:1. Main functions- Exhaust air: Automatically or manually release air or other gases in the pipeline to ensure smooth flow of fluids (such as water, oil, and steam).- Prevent vacuum: Some exhaust valves can inhale air when the system is emptied to avoid the formation of vacuum.- Protect equipment: Reduce cavitation, water hammer and other phenomena, and extend the service life of components such as pumps and pipelines.2. Common types- Automatic exhaust valve:- Float type: Use the float to control exhaust as the water level rises and falls, and the valve automatically opens to exhaust when air accumulates.- Diaphragm type: The diaphragm is driven to open and close by changes in air pressure, suitable for small systems.- Manual exhaust valve:- Manual operation is required (such as knob or screwdriver to open), commonly found in radiators or local pipelines.- Compound exhaust valve:- Combines automatic exhaust and high-speed exhaust functions, suitable for high-pressure or large-flow systems (such as water supply networks).- Vacuum breaker valve:- Prevents pipe collapse or backflow due to negative pressure when the system is shut down.3. Application scenarios- Water supply system: Remove air from high-rise buildings and municipal pipes to avoid water hammer.- Heating and ventilation system (HVAC)**: Exhaust air from radiators and floor heating pipes to ensure heating efficiency.- Industrial pipeline: Gas-liquid separation in petroleum, chemical and other fields.- Wastewater treatment: Exhaust of aeration tanks and water pipelines.Detailed PhotosProduct ParametersBodyDuctile iron GGG50 /SSS304/SS316CoverDuctile iron GGG50 /SSS304/SS316SealingRubber EPDMSealing seatBrass ZCuAI10Fe3SizeDN50-DN300mmStandardBS,DIN,ENPN1.0/1.6MpaConnectingFlange/ThreadWorking temp.NBR≤80oC/EPDM≤120oCCoatingFusion-bonded epoxy 200-250 microns inside and out sideCertificationsPackaging & ShippingCompany Profile Tianjin Yoakor Machinery Equipment Co., Ltd. founded in 2018, is an ISO 9001 certified company,committed to manufacturing valves& related products for water works and Environmental protection machinery equipment.Now the company has become a set design, development,production, manufacturing, sales in one of the valve manufacturing enterprises.The company's mechanical processing, welding heat treatment, The production and testing center includes assembly pressure testing, physical and chemical testing, etc.Yoakor mainly producebutterfly valve(Concentricand Eccentric), gate valve(Resilient seat,Metal seat),,check valve,globe valve,strainers,discharge valves, screw conveyors and environmentally friendly dust removal equipment.
