Low Pressure Manual Diaphragm Valves

FITOK DQ Series Low Pressure Manual Diaphragm Valves are designed to offer low internal volume, minimal particle generation and no dead spaces, ensuring a fully swept flow path and preserving media purity. Their contained seat resists swelling and contamination, while the cobalt alloy diaphragm ensures a long cycle life, high strength and excellent corrosion resistance. The metal-to-metal seat prevents external leakage, and windowed handles clearly show the open or closed position.

These valves are widely used in gas and liquid dosing and control processes, in environments where reliability, cleanliness and chemical compatibility are essential. To suit different installation layouts and process requirements, they can be fitted with position sensors, solenoid valves and bodies with ports for heater cartridges and thermocouples, offering maximum flexibility and control.

Thanks to these features, DQ series low pressure manual diaphragm valves combine precision, cleanliness, durability and flexibility, making them ideal for critical applications in the semiconductor industry, laboratories and high purity and ultra purity processes.
