Shanghai Jipai Fluid Control Technology (Group) Co., Ltd

The core advantage of GP-24.4 high vacuum angle valve lies in its excellent reliability and flexible variability. This series is designed to deal with highly polluted or even slightly polluted airflows, and supports large-scale manufacturing. Currently, models with export diameters up to DN 800 mm (32 "") have been produced.
With multiple drive modes, flange connection forms, valve body materials, and sealing structure design options, the GP-24.4 series can almost meet the integration needs of various vacuum systems. This series is particularly suitable for vacuum system pumping and exhaust, and can withstand high pressure differentials.
Its modular design not only facilitates adjustments according to specific process and operational requirements, but also ensures a long service life and excellent reliability.
