Product Overview
The ENTEGRIS NSTM-12D-TR is a high-purity fluid valve engineered for critical process and pneumatic control applications where media integrity and leak-tight shutoff are paramount. Operating on a direct-acting, normally-closed pneumatic actuation principle, this valve utilizes a precision-machined diaphragm or bellows isolation mechanism to prevent media contact with wetted metallic components, ensuring ultra-low particle generation and minimal extractables. As a core component within high-purity fluid handling systems, it serves as a reliable interface for controlling aggressive chemicals, ultrapure water, and specialty gases in semiconductor, pharmaceutical, and advanced industrial processes. Its compact, modular design allows for integration into space-constrained manifolds and gas panels, delivering consistent flow control and rapid response times essential for automated process cycles.
