A range of check valves which can be integrated into high volume, automated assembly lines and provide a cost-effective alternative to in-house check or relief valves, is available from Lee Products.

    The robust design of these valves and 100% testing ensures consistent, long-term performance up to 28MPa in temperatures up to 149C.

    However, operation in higher temperatures is possible depending on specific application requirements.

    IMH Check valves are compact, threadless, cartridge style inserts designed for simple, low-cost installation into manifolds.

    They benefit from the proven Lee Chek metal-to-metal seating design, which ensures high reliability and long life.

    For example, the high quality hard seat design feature limits leakage in the checked direction to no more than 20cm3 of air at 172kPa differential.

    The Series 855 is a guided ball design, which ensures the ball is aligned with the valve seat to provide a positive stop and prevents the spring from going solid.

    They have an outside diameter of 8mm, provide forward and reverse flow direction of 4MPa and a maximum working pressure of 28Mpa.Fore more information ,please visit http://www.bossgoo.com/
