The series 273 are 2-Way normally closed and normally open pressure-operated pinch valves designed for use with high-purity liquids in biotech applications. The pneumatic pinch valve is also available as a 3-way normally closed and normally open valve, designed for chromatography applications. Hermetic separation of control mechanism and the fluid within the tubing prevents contamination, assuring maximum purity of liquids. Available in a large range of body sizes to accommodate a wide variety of tubing sizes. Typical applications include single-use bioreactors, Tangential Flow Filtration (TFF), and Chromatography skids.
Valin supplies a full range of rugged, reliable valves from the highest quality suppliers in the industry. Our valve solutions provide long lasting tight shut-off with fast and safe operation together with reduced fugitive emissions. Tough steel and stainless steel valves give reliable, cost-effective performance for most processes. High alloy materials like Hastelloy, Monel, Titanium, Carpenter 20 and Duplex Stainless Steels are available for systems with aggressive chemistry. Or try our thermoplastic, polymer and fiber-composite options to reduce cost and weight. And ultra-hard materials like Stellite and Ceramics can stand up to your most abrasive processes. Whatever you are dealing with, our process experts can help you find the right solution.
Increased plant run-time targets set new challenges for control valve reliability, performance and safety. Processes are ever more challenging requiring valves that can control higher temperatures and pressures; harsher chemicals and abrasives; scaling, crystallization and polymerization; cavitation, flashing and hazardous materials. Valin’s broad control valve offering provides solutions across every ANSI pressure class and pressure drop range. Valin’s manufacturing partners are looking to the future to provide the very latest in intelligent valve controller options with an understanding of the need for predictive maintenance indicators so plant managers can proactively maintain the plant’s final element population. Valin’s control valve sizing and selection tools coupled with in-house expertise allows our sales engineers to provide the highest value solution available. We partner with you to ensure your process variability is minimized, helping to avoid production losses, upsets and waste of energy or raw materials.
