Plunger valves typically have straight cylindrical designs for on/off control, while needle valves feature tapered tips for precise flow regulation. Needle valves provide finer control with gradual opening characteristics.
Material selection depends on fluid compatibility, pressure requirements, and wear resistance. Stainless steel offers corrosion resistance, tool steel provides durability, and ceramics handle abrasive fluids. Consider chemical compatibility charts and operating conditions.
Regular inspection for wear, cleaning to prevent contamination buildup, lubrication of moving parts, and periodic replacement based on operational hours or cycle counts. Monitor for leakage and performance degradation.
