The castings utilize German coated sand casting technology, achieving a smooth surface finish of 12.5-25 microns. Mechanical performance is excellent, with over 98% of castings free from defects such as pores, sand holes, or cracks, ensuring standard wall thickness.
The valve features a conical seal design that prevents impurity residue and provides a self-cleaning effect during closing. This conical surface amplifies the stem's axial force into sealing force for superior performance.
A dual-seal design combining bellows and packing provides double security, ensuring stem sealing meets international standards. Bellows are 100% fugitive emission tested according to ISO15848 Class A, and all assemblies are 100% tested to ensure zero leakage.
