Product Description
JHL-16 is a spring-loaded valve that can be adjusted with its ACME rising stem from a full flow position to complete shut-off. Automatic shut-off is achieved via the spring assisted disc that closes near zero flow velocity helping to prevent flow reversal, slamming, and surges that could harm the pump.
 
Tri-flow Control Check Valve include a graduated position indicator on the stem for an accurate check of the valve's position and a hand wheel for ease of operation. The soft-seated, dovetail, o-ring groove ensures a bubble tight seal in the closed position. The disc's low cracking pressure reduces the amount of energy required to open the valve and the valve's large body minimizes head loss across the valve.
