Series III-L Actuated Heavy-Duty Valve

Brand: Barksdale

With the ability to handle high pressure demands between 3,000 to 5,000 psi while maintaining a high flow capability of 75 GPM, the Series III-L is well suited to tolerate contaminated media.

The combination of the high flow and high pressure and virtually zero-leakage* makes the Series III-L valve the choice for the toughest applications where zero-leakage* is a must. * 0.17 cc/min (maximum 4 drops/min).
