Valves

Control the flow with our extensive selection of gas and liquid valves, designed to meet the diverse needs of laboratory and industrial applications. We offer a wide variety of valve types, including ball valves, diaphragm valves, needle valves, rupture discs, relief valves, solenoid valves, and switchover systems, ensuring precise and reliable control over your fluid and gas systems.

Our inventory features high-quality valves from leading brands such as Watersaver, Airgas, PBM, Millipore, ASCO, Parker, and Swagelok. Ball valves provide quick on/off control, while diaphragm valves offer excellent chemical resistance. Needle valves allow for fine-tuning of flow rates, and rupture discs provide critical overpressure protection. Relief valves prevent damage to equipment by relieving excess pressure, and solenoid valves enable automated control of fluid flow. Switchover systems ensure continuous operation by automatically switching between gas sources.

Whether you're working with liquids or gases, our comprehensive selection of valves will help you achieve accurate and reliable control over your fluid systems. Browse our subcategories to find the perfect valves for your specific application needs.
