Engineered for reliability, these check valves provide precise, one-way flow control to protect sensitive equipment and ensure system integrity. By preventing backflow with a dependable seal, these valves are an essential component for any fluid or gas handling system where unidirectional flow is required. The polycarbonate housing is a strong, stiff, and optically clear thermoplastic valued for durability and impact resistance and widely used in industrial and consumer goods. The silicone diaphragm is the perfect choice for high-purity applications, offering excellent performance across a wide temperature range and outstanding sealing properties. Its flexibility and cleanliness make it highly suitable for medical, laboratory, and food and beverage use. Note: See the material spec sheet for more detailed information on the housing material.
