Teknik Bilgi

Barksdale's Series III-L valve provides an optimal solution for the upmost reliability and safety by combining the dependable features of our heavy duty Shear-Seal® valves with the reliability of the integrated actuator, providing an all in one package saving customers time in installation and maintenance. With the ability to handle high pressure demands between 3000 to 5000 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.
