Air Valve Supplier in Kenya for Reliable Valve Solutions

Air Release valves play a critical role in controlling air movement within pressurized liquid pipelines, helping release accumulated air during operation while admitting air when pipelines are drained or subjected to vacuum conditions. For projects sourcing an Air Release Valve Supplier in Kenya, African Valve offers configurations suited to different pipeline sizes, pressure classes and service conditions. The range covers single-orifice, double-orifice, kinetic and combination air valves for applications across water infrastructure, irrigation, mining, oil & gas, wastewater, power generation and industrial process systems.

Air Release Valve Features

Automatic air release - Removes accumulated air from pressurized pipelines.
Vacuum protection - Admits air during draining or negative-pressure conditions.
Continuous air release - Removes smaller air pockets during normal pipeline operation.
High-volume air movement - Allows rapid air intake and exhaust during pipeline filling and draining.
Corrosion-resistant construction - Material options can be selected according to service conditions.
Project-specific configuration - Size, pressure rating, materials and connections can be selected according to system requirements.

Material selection: Ductile iron EN-GJS-500-7 is a common choice for water-service pressure bodies because it provides good strength and impact resistance; EN-GJL-250 is used for cast-iron construction, while ASTM A216 WCB and ASTM A351 CF8M provide carbon-steel and corrosion-resistant stainless-steel alternatives respectively.

Applications in Nigeria

Air valves are used in water and irrigation networks, pumping mains, mining pipelines, oil & gas and petroleum systems, wastewater infrastructure, power generation and industrial process pipelines. They are particularly important at pipeline high points, elevation changes and locations where air accumulation or vacuum conditions may occur.

Testing & Standards

Air valves can be designed in accordance with EN 1074-4 and AWWA C512, with flange dimensions following applicable EN 1092-1 or ASME B16.5 requirements. Testing and inspection are determined by the selected design, pressure rating, materials and project specifications.
