Sliding Gate Valve With Variable Orifice

430 views

Published on

The GS valve is a high performance variable orifice control valve. Known as a sliding gate valve, the GS3 seat design features a non turbulent, straight through flow path. The flow is broken apart into multiple streams creating a reduced field of energy. The result is greater service life, quieter operation and a control valve that performs at the highest levels possible within extreme conditions. Maximized temperatures and pressures, 986 F and 1,450 psi. Sizes 1/2″ – 10″ (DN 15 – 250) Carbon Steel and 316 Ti Stainless Steel, and Hastelloy C4 in select sizes.
