Safety Warning

Full Product Description

Parker’s LC-Series Lift Check Valve has been designed for a wide variety of temperature extremes from -100⁰F to 900⁰F (-148⁰C to 482⁰C). To achieve this performance, the check valve must be mounted in the proper orientation as the bonnet nut is clearly marked. In contrast to a general purpose lift check valve, the LC-Series has been designed to prevent flow in the reverse direction to within 99.9% of forward flow. This is ideal for liquid service applications. The gravity assisted poppet uses back pressure to achieve a seal.

Many industrial valves of this type require additional fittings (adapters) when connecting to tubing system. The LC Series does not require adapters and offers both single ferrule and two ferrule compression end connection integral to the valve body
