ISO63 Gate Valve, 2.5 inch Manual Gate Valve, Viton Gate / Viton Bonnet Seals, ISO63 Metric Bolt Flanges, Stainless Steel (PN 11110-0253) In the simplest of terms, HVA vacuum gate valves are devices that regulate the flow of gases, fluids or materials through a structure or aperture by opening, closing or obstructing a port or passageway. Gate valve assemblies consist of three key components: an actuator, a carriage/gate and a valve body. The actuator provides the power to position or transport the valve’s carriage/gate. The actuator is attached to the valve’s body via a rectangular bonnet flange. The gate closes or opens one of the valve’s body ports. The valve body is a vacuum tight chamber that is screwed, flanged or welded into a larger vacuum vessel or system. The 11000 Series Gate Valves feature a positive lock-over center mechanism. Linear actuation allows the use of a welded bellows to seal the actuator (i.e. no rotary seals). Shock and vibration are reduced to a minimum by a unique air cylinder design. This feature is extremely beneficial for semiconductor fabrication and other sensitive processing requiring operation which is relatively free of vibration. The HVA stainless steel body offers one of the smallest interior surface areas in the vacuum valve industry. The body and all major internal components are vacuum furnace brazed at 1100°C, at 1x10-6 Torr, ensuring maximum joint integrity. This eliminates the possibility of virtual leaks or entrapment areas and minimizes body distortion found in conventionally welded valves. For maintenance purposes, the carriage assembly can be removed from the body without removing the valve from the system. This is a 1100 Series Standard Cycle Manual Gate Valve UHV (Ultra High Vacuum) with a ISO 63 Port Flange and a 2.5 inch ID opening. For Spcecifications see graphic below.
