Valve & Pump Refurbishment
Valve maintenance and refurbishment are critical components of ensuring the operational efficiency and longevity of industrial machinery and systems. Siyanda Engineering stands at the forefront of this essential service, offering comprehensive solutions for valve seat replacement, valve body refurbishment, and a suite of additional services designed to restore valves to their original equipment manufacturer (OEM) condition.
Valve Seat Replacement
Siyanda Engineering possesses advanced capabilities to replace valve seat hard facings with a variety of alloys, including Stellite 6, renowned for its exceptional performance in high-temperature applications. The process involves the use of perfected automated welding techniques that guarantee defect-free seat refurbishments. This specialized approach ensures that valve seats are restored to meet stringent operational standards, thereby extending the service life of valves and enhancing system reliability.
Valve Body Refurbishment
The expertise at Siyanda Engineering extends to the comprehensive refurbishment of valve bodies for various nominal bores and types, including:
Non-return Valves:
Critical for preventing backflow and ensuring fluid or gas flows in one direction only.
Wedge Gate Valves:
Utilized for on-off control of fluid flow, offering reliable sealing capabilities.
Governor & Stop Valves:
Essential for controlling flow and pressure within systems, playing a crucial role in safety and operational efficiency.
Control Valves:
Key components in regulating system flow and pressure according to desired setpoints.
Where necessary, Siyanda Engineering can manufacture worn components such as internal spindles, guides, bushes, and fasteners. This ensures that each refurbished valve not only meets but exceeds OEM specifications, providing renewed performance and reliability.
