Manual ultra-high-vacuum gate valves in nominal sizes DN35–DN400. KYKY CC valves use CF or ISO-F flanges, mechanical position indication and a specified leak rate of ≤1.3 × 10⁻¹⁰ Pa·m³/s.
Description
KYKY CC Manual Ultra-High-Vacuum Gate Valves
The CC series uses a handwheel and lead-screw mechanism to move the gate between open and closed positions. These compact valves are intended for air and non-corrosive gases in research, coating, leak-detection and industrial vacuum systems.

The legacy source page added ISO-K variants and a 10−7 Pa lower range without support from KYKY's current product data. This page uses the documented CF/ISO-F series and 10−6 Pa range.
Select the exact model from the required bore, flange, seal compatibility, bakeout duty and conductance. Confirm dimensions, sealing material and supplied fasteners from the current drawing.
