Description

Zero leak versions of the detented and spring-biased shuttle valves are available with polymeric valve seats to eliminate leakage. Detented shuttle valves are available with polymeric seats on both the normal and emergency ports. These polymeric seats provide a tighter seal in applications where eliminating any leakage is critical. This is particularly critical in applications using a gas-operated backup emergency system. Contact your local Lee Sales Engineer for custom versions of a spring-biased shuttle valve with a polymeric valve seat. This miniature shuttle valve is only .187” in diameter and .93” in length. The poppet in this shuttle valve is biased so that the emergency port (E) is normally closed, and the normal (N) and service (S) ports are connected. It is ideal for applications with flow rates up to 1.3 gpm. The valve has integral safety screens for added protection against rogue contamination or debris. This miniature shuttle valve is only .250” in diameter and 1.65” in length. The poppets in this shuttle valve are designed to allow the lower inlet pressure to flow while the higher inlet pressure is blocked. It is ideal for applications with flow rates up to 3 gpm. This miniature shuttle valve is only .375” in diameter and 1.37” in length. This shuttle valve incorporates a detent mechanism that can latch the poppet at either of the inlet ports. This is beneficial when bi-direction flow is needed in either poppet position. It is ideal for applications with flow rates up to 13 gpm.
