9. Features & Applications

• Key Features:
• Vacuum Service Compatibility: Specially designed for high vacuum applications down to 10⁻⁶ mbar, with helium leak testing to verify integrity.
• Double Block & Bleed: 3-piece design allows for positive isolation and safe maintenance.
• Low Outgassing Materials: Stainless steel body with RPTFE/PTFE seats minimizes contamination of vacuum systems .
• Full Bore Design: Minimal pressure drop and easy system evacuation .
• Blow-out Proof Stem: Ensures stem retention under all pressure conditions .
• Anti-Static Device: Dissipates static charge, critical for vacuum systems where static buildup can occur .
• Fire-Safe Design: Optional API 607 certification ensures sealing integrity in case of fire.
• Forged Body: Provides superior strength and reliability at high pressures and vacuum conditions .
• 3-Piece Construction: Allows for easy maintenance and in-line repair without removing pipe ends .
• Lockable Handle: Provides safety lockout capability for maintenance .
• Main Applications:
• Semiconductor Manufacturing: Vacuum processing chambers and gas delivery systems.
• Research Laboratories: High vacuum experimental setups.
• Pharmaceutical Industry: Freeze drying (lyophilization) systems.
• Analytical Instruments: Mass spectrometers, electron microscopes.
• Space Simulation: Vacuum chambers for testing.
• Coating Industries: PVD/CVD vacuum coating systems.
• General Vacuum Systems: Where reliable isolation from atmosphere is required.
