Continuous improvement, optimization, and innovation of existing products have always been our pursuit.

The Y-shaped and T-shaped bellows valves independently developed by GPTECH are based on similar products at home and abroad, using GB/T1048-2005/GB/T12224-2005/JB/T3595-2002/ASME B16.34-2004 standards. Through precise calculation and repeated testing of valve body wall thickness, packing device, valve stem nut and other parts, combined with our years of experience in the fluid industry, we have made improvements and optimizations in the production process of valve media working pressure and working temperature, valve driving mode, valve sulfur resistance, corrosion resistance and anti-static requirements. In practical application and testing data, they are not inferior to similar products of Dockweiler and Swagelok, and are one of the core products of Jipai Fluid.
