Explore our core custom-manufactured product portfolio designed for high performance under extreme pressures.
In modern piping infrastructure, the entrainment of air and other gases is an inevitable challenge. Air enters fluid transmission systems during initial line filling, pump start-ups, and through pocket formations created by local pressure fluctuations. Left unmanaged, trapped gas pockets cause significant operational inefficiencies, including severe flow capacity restrictions, accelerated pipeline corrosion, erratic control valve oscillations, and high-energy water hammer incidents.
An automatic air vent serves as a safety mechanism, continually venting accumulated micro-air bubbles before they coalesce into catastrophic gas pockets. As a leading manufacturer with over 20 years of technical expertise, KR Valve designs and supplies custom automatic air vents engineered to maintain absolute system integrity. Our valves deliver dynamic kinetic air release, rapid air vacuum mitigation, and continuous venting under standard working pressures.
By purging air instantly, our vents prevent localized vapor bubble collapse, eliminating the mechanical pitting and structural vibrations that degrade impellers and pipeline linings.
Purging pockets optimizes flow cross-sections, lowering pumping friction coefficients and minimizing electrical power demands across municipal water networks.
Provides critical air-cushioning and intake properties, ensuring pipeline safety during column separations and vacuum events under abrupt power outages.
Comprehensive engineering benchmarks for custom automatic air release valve design.
Industrial automatic air vents are installed at high system elevations where air naturally accumulates. Our R&D team continuously customizes valve structures to align with regional projects. While standard air release valves rely on simple spherical float mechanisms, KR Valve integrates advanced dual-port configurations and variable-geometry levers to operate flawlessly up to PN16 / PN25 pressure limits.
Depending on your specific application environment, we offer several custom-designed material variants:
| Valve Type | Material Configuration | Standard Connections | Pressure Class (PN) | Core Application |
|---|---|---|---|---|
| Single Port Air Exhaust Valve | Ductile Iron GGG40 / SS304 Internal | Flanged DIN / BS / ANSI | PN10 / PN16 / PN25 | Municipal Clean Water Distribution |
| Two Port Vent & Regulation Valve | Cast Steel WCB / Ductile Iron | NPT / BSPT Threaded, Flanged | PN16 / PN40 | High Velocity Water Supply & Power Generation |
| Corrosion Resistant Vent Valve | SS316 CF8M / PTFE Lined Body | Flanged ANSI 150LB / DIN | PN10 / PN16 | Desalination Plants & Acid Recovery Systems |
| Wastewater Rapid Release Valve | GGG40 with Epoxy Coating >300μm | Flanged DN50 to DN300 | PN10 / PN16 | Raw Sewage Treatment & Irrigation Outlets |
Ensuring absolute alignment with global design guidelines, material standards, and regional certifications.
No two global pipeline projects are identical. Factors such as soil salinity, atmospheric humidity, aggressive chemical media, and dynamic surge profiles demand highly customized product designs. Through KR's in-house design capabilities, we convert customized pipeline specifications into high-performance solutions.
Whether you require unique flange drillings (BS4504, DIN2501, ANSI B16.42), customized low-pressure sealing seats, or visual telemetry indicators for automated system control, we configure our manufacturing lines to meet those needs. With over 30 advanced production machines and in-house CNC machining lines, we scale up production to keep lead times brief.
Every phase of our raw material sourcing, casting, machining, assembly, and testing conforms strictly to ISO 9001 quality management guidelines.
We perform 100% hydrostatic and pneumatic seal inspections on all completed valve assemblies, ensuring bubble-tight performance under high and low pressures.
Exporting to more than 50 countries in Europe, Asia, Africa, and the Americas, we provide full clearance documentation and specialized transit packaging.
