Manual Aluminum Angled Block Valves (KF Flanged)
Our Manual Aluminum Angled Block Valves are engineered for both rough and high vacuum environments, making them suitable for applications down to pressures of less than 1 x 10⁻⁹ torr. These valves are bakeable up to 100°C, ensuring versatility in various operational conditions.
Key Features:
- Leak Rate Assurance: Main valve seal leak rate tested at less than 1 x 10⁻⁹ std cc/sec with helium during manufacturing.
- Actuation Options: Available with manual, pneumatic, and electromagnetic actuators.
- Manual Operation: Manually actuated valves feature a quick-acting lever connected to a self-lubricating cam-piston for precise valve stem actuation.
- Smooth Operation: PTFE bearings guarantee smooth action during operation.
- Low Maintenance: Sealed grease-free bellows minimize maintenance needs while enabling reliable operation up to 100,000 cycles.
