The SMC XLG-40 is a high vacuum corner valve designed for applications requiring reliable vacuum sealing and minimal leakage. Its key features include:

• Construction Materials : The valve body is made from aluminum alloy, with stainless steel components and FKM (fluororubber) as the standard seal material.
• Operating Range : It functions efficiently in pressures from 1 x 10⁻⁶ Pa (absolute) to atmospheric pressure, making it suitable for high vacuum conditions.
• Leakage Rates : Internal leakage is rated at 1.3 x 10⁻¹⁰ Pa·m³/s, and external leakage at 1.3 x 10⁻¹¹ Pa·m³/s, ensuring high sealing integrity.
• Flange Compatibility : It supports KF (NW) and K (DN) flange types.
• Pilot Pressure : Operates with a pilot pressure range of 0.4 to 0.7 MPa.
• Optional Features : Available with auto switches and CE-compliant solenoid valve options for enhanced functionality.
