Histen 2-Piece Reduced bore Ball valve is desinged to maximize flow with minimum pressure loss.
Insertion of O-ring in stem part to optimize leakage protection regardless of tighten the handle nut.
There is no leakage when the handle disassembled for maintenance for PN20 type and Steam type.
Stainless steel body, handle and parts, applied unique solution heat treatment technology, have 2 times higher corrosion resistance and strength than ordinary stainless steel products.
Precision machining is applied to thread and stem part to minimize burr on surface.
High quality sealing materials and optimized design prevent leakage of fluids
