Direct from Factory: Fully compatible with local Sri Lankan industrial pipeline environments.
As Sri Lanka emerges as a high-value manufacturing hub in South Asia, local industries in Free Trade Zones like Katunayake, Biyagama, and Koggala are shifting from manual labor to automated pneumatic machinery. From high-speed fabric cutting and sewing machines in the apparel sector to precision tea drying and grading systems in Kandy, the demand for precise pneumatic control has grown exponentially.
However, Sri Lanka’s unique tropical environment poses significant challenges. High relative humidity (often exceeding 80%) coupled with high coastal salinity in cities like Colombo and Hambantota leads to rapid corrosion in metal parts. Standard brass components oxidize quickly, causing leakage, pressure drop, and eventual failure of the cylinder movement.
This is where NHPC's premium flow controller throttles and speed controllers offer a vital upgrade. By utilizing high-grade nickel-plated brass bodies, engineering plastic (PBT) collets, and fluororubber (Viton) seals, our valves offer the longevity and structural integrity required to combat harsh humid climates while maintaining consistent air velocity and pressure control.
Our pneumatic flow control throttles feature multi-layered nickel plating (up to 15μm) that outperforms standard components by 250% in standard salt spray tests. This guarantees zero lockup in coastal tea packaging and textile processing lines.
Understanding the engineering parameters that drive optimal pneumatic speed adjustment.
For double-acting pneumatic cylinders typical in Sri Lankan packaging lines, regulating the air leaving the cylinder (meter-out) is critical to prevent stick-slip motions. Meter-out speed controllers allow for a backpressure cushion, ensuring stable actuator travel even under fluctuating loads. NHPC manufactures both variants with distinct visual indicators so that your assembly engineers can easily identify flow directions on the shop floor.
In pneumatic pipelines, thread connection reliability is the primary determinant of system efficiency. Our SL and SLG series incorporate high-performance G-thread (parallel) configurations with integrated O-rings, alongside traditional BSPT/NPT threads pre-coated with sealant. This eliminates the need for manual Teflon tape application, significantly reducing installation time in massive plant setups in Gampaha and Kurunegala.
Every single throttle valve is subjected to automated dual air pressure leak testing before packaging, ensuring zero loss at up to 15 bar.
Rotatable elbow configuration allows flexible installation in compact or complicated pneumatic pipeline layouts.
Bodies built using self-extinguishing PBT, essential for battery assembly and fire protection systems.
