The manual drain valve is a specially designed single-seat control valve, featuring an integrated direct-flow Y-shaped structure with unobstructed flow paths, ensuring smooth fluid passage. The internal surface is sandblasted, making it smooth and free from dead zones, preventing fluid stagnation or accumulation within the valve. This valve is particularly suited for industries such as fine chemicals and pharmaceuticals, effectively controlling the on-off flow of fluids prone to sedimentation or containing particles, ensuring stable fluid flow and preventing clogging or damage to equipment.
