Product Overview
The SMC ZHV20 is a high vacuum angle seat valve engineered by SMC Corporation, a global leader in pneumatic and vacuum control technology. Designed for precision vacuum isolation and pressure control, this valve operates on a pneumatically actuated piston mechanism that ensures rapid, reliable shut-off in high vacuum circuits. Its robust construction and elastomer sealing technology make it an essential component in industrial vacuum systems, semiconductor manufacturing, and process automation where maintaining vacuum integrity is critical. The ZHV20 is specifically engineered to handle vacuum pressures down to 1.3 x 10-1 Pa while providing leak-tight performance and long service life.
