African Valve’s Low Lift Safety Valve delivers fast-acting, precise pressure relief in high-pressure systems.
Pressure protection systems do not always require maximum discharge capacity. In many applications, a controlled release of excess pressure is sufficient to maintain safe operating conditions without unnecessary flow loss. A Low Lift Safety Valve is manufactured to open through a limited valve lift, providing measured discharge while protecting equipment from overpressure. Its compact construction and repeatable operating characteristics make it suitable for steam, air, gas, and other compressible media where moderate relieving capacity is required. African Valve is a Leading Low Lift Safety Valve Manufacturer in Africa, manufacturing and supplying Low Lift Safety Valves in various material grades, pressure classes, end connections, and pressure settings for projects across Nigeria, Egypt, South Africa, Kenya, Ghana, and other African countries, along with international export destinations. During normal operation, the spring assembly keeps the valve disc firmly seated against the nozzle, preventing media from escaping. As system pressure gradually approaches the calibrated set pressure, the force acting beneath the disc increases until it overcomes the spring load. The disc then rises through a predetermined low lift, allowing excess pressure to discharge in a controlled manner. Once the pressure falls below the reseating point, the spring returns the disc to its original position, restoring a tight seal and preparing the valve for the next pressure cycle. The construction of this valve consists of a body, nozzle, disc, spindle, spring cage, bonnet, adjusting screw, and a guide assembly. This valve design allows for valve movement and reduces vibrations during its operation. Adjustment of set pressure is done through variation of the amount of spring compressions. Lifting levers, bellows, and various seating materials may be applied depending on the need of the application. The valve is manufactured using: Carbon Steel – ASTM A216 WCB Stainless Steel – ASTM A351 CF8 / CF8M Chrome Moly Alloy Steel – ASTM A217 WC6 / WC9 Duplex Stainless Steel – ASTM A995 Grade 4A Bronze – ASTM B62 Construction features include: Low Lift Spring Loaded Design Precision Machined Nozzle and Disc Adjustable Pressure Setting Blowdown Adjustment Ring Balanced Bellows Construction (Optional) Open or Closed Bonnet Design Flanged, Threaded, and Butt Weld End Connections Size Range: DN15 to DN200 (½" to 8") Pressure Ratings: Class 150, 300, 600, 900 Design Standards: API 526, ASME Section VIII, ASME B16.34 Testing Standard: API 527 End Connections: Flanged, Threaded, Butt Weld Operation: Spring Loaded Low Lift Safety Valves are widely used in: Steam Systems Air Compressors Pressure Vessels Gas Distribution Equipment Utility Pipelines Boiler Auxiliary Systems Chemical Processing Plants Process Equipment Protection Controlled discharge for moderate-capacity applications Stable opening and dependable reseating performance Compact design for space-efficient installations Adjustable pressure settings to suit process requirements Suitable for steam, gas, and compressed air service Manufactured according to internationally recognized engineering standards Low Lift Safety Valves are manufactured according to international engineering standards and customer project specifications. Each valve undergoes dimensional inspection, hydrostatic shell testing, seat leakage testing, pressure calibration, blowdown verification, functional testing, and final quality inspection before dispatch. Material Test Certificates (MTC), pressure test reports, calibration records, inspection reports, and supporting documentation are available to satisfy engineering, procurement, and project compliance requirements. African Valve provides Low Lift Safety Valves for use in power plants, utility systems, boilers, gas processing systems, pressure equipment makers, and process plants in Nigeria, Egypt, South Africa, Kenya, Ghana, and other African nations. The valves come in various material grades, pressure ratings, ends, and pressures to serve specific project needs.Low Lift Safety Valve Manufacturer in Africa
