Ideal Vacuum UltraLock High Vacuum HV Pneumatic Gate Valve ISO-F DN 63 Flange, Ball Groove Locking, Viton Seals, 304 Stainless Steel. ISO-63 Bolt Down Flange with M8 x 1.25 Threads. Includes Reed Switch Position Indicators. These Ideal Vacuum UltraLock™ pneumatically operated gate valves have an ISO-F DN 63 vacuum flange with M8 x 1.25 blind-tapped holes. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. Our new UltraLock series of premium pneumatically operated vacuum gate valves are built using an innovative ball-and-groove locking mechanism which keeps the valve locked closed during loss of power or air pressure, while reducing wear and extending operating life. These UltraLock gate valves have a typical life of 300,000 cycles before needing service and are made with corrosion resistant 304 stainless-steel gates and valve bodies. An easily visible external position indicator and position sensor switches are standard on all pneumatic UltraLock gate valves.UltraLock Locking Mechanism: Our UltraLock high vacuum gate valves employ an ingenious ball-and-groove mechanism to lock the valve. Inside the valve body is a rolling carriage with lubricated ball bearings on which the gate is attached. When the valve is actuated, the carriage and gate are slid towards the vacuum port until the carriage reaches the end of the valve body. This positions the gate concentric to the port. Continued pressure on the carriage causes a set of stainless-steel balls, riding in a decreasing depth groove between the carriage and the gate, to exert outward pressure on the gate. This outward force pushes the gate into its closed position. A leak-tight seal is obtained as the outward pressure forces the gate’s O-ring seal to be pressed against the valve body’s sealing surface. It is common for these valves to achieve an extended life of 300,000 cycles before service is needed. UHV vs HV Versions: Our Conflat CF flanged gate valves are UHV rated. The bellows are welded to the bonnet plate, and oxygen-free, high-thermal conductivity (OFHC) copper sealing gaskets and flange knife-edges form the required metal-to-metal seal between the bonnet plate and valve body. Our Conflat UHV UltraLock valves have a low leak rate of < 3.75 x 10-10 Torr l/sec and are bakeable up to 200 °C with the gate open (150°C with the gate closed). Our KF and ISO-F flanged gate valves use Viton O-rings for the bellows and bonnet plate seals and are therefore limited to high-vacuum (HV) applications with ultimate pressures down to 3x10-8 Torr. KF and ISO-F series UltraLock valves have a leak rate of 1.5 x 10-9 Torr l/sec and are bakeable to 150 °C (with the valve open or closed). Position Indicators: All of our UltraLock series of pneumatic gate valves include a visible external position indicator - the white ring conveniently mounted below the pneumatic piston. Pneumatic UltraLock gate valves also include open and closed reed sensor switches which are mounted on the valve’s pneumatic cylinder. These switches can be used to activate indicator lights or used to control a more complex or automated vacuum protection system. Solenoid Valves: We offer solenoid kits for pneumatic valves in voltages of 12 VDC, 24 VDC, and 120 VAC. Solenoid kits are sold separately and include the solenoid valve, mounting bracket with fasteners used to attach the solenoid to the gate valve’s bonnet flange, and flexible 1/4” OD airlines to connect between the push-to-connect fittings on the gate valve’s pneumatic cylinder and the solenoid valve. Specifications: Our Ideal Vacuum UltraLock gate valves are designed for dependable High and Ultra- High Vacuum (UHV) applications and are often used in combination with cryo, turbo, and ion high vacuum pumps. Available sizes include Conflat CF 2.75, 4.5, 6, 8, 10, and 12 inch sizes; ISO-F DN -63, -100, -160, -200, -250, -320, -400, -500, and -630 sizes; and quick flanged sizes KF-40 and KF-50.

Ideal Vacuum 3-Position HV Pneumatic Operated Gate Valve, Throttled 3rd position, With Solenoid and Reed Sensors, 24VDC, ISO-F 200 (DN 200) Flange, Viton O-ring Standard Seal, 1x10-8 Torr, SUS304 Body, 300,000 cycles This Ideal Vacuum 3-Position Throttle Gate Valve is pneumatically operated with a ISO-F 200 (DN CF200) flange. It has a 3rd position that can be set to partially open. It is rated for high vacuum (HV) and comes with a standard Viton O-ring seal for the gate and Viton O-ring or OFHC copper gasket for the bonnet with a pneumatic controlled solenoid valve. This ISO-F flanged gate valve use Viton O-rings for the bellows and bonnet plate seals and are therefore limited to high-vacuum (HV) applications with ultimate pressures down to 1x10-8 Torr. The valves have a typical life of 300,000 cycles before needing service. They are made with corrosion resistant 304 stainless-steel gates and valve bodies. This 3-position control provides flexibility and precision in maintaining optimal conditions for various vacuum deposition processes, particularly in thin films deposition process chamber systems. Application in Physical Vapor Deposition Coating Chambers This 3-position gate valve is designed for dependable high vacuum applications and are often used in combination with cryo, turbo, and ion high vacuum pumps. It has found increased usage in throttled vacuum processes like PVD magnetron sputtering deposition. In a PVD coating chamber, such as in sputtering systems, a 3-position gate valve is often used to control the connection between the turbo-molecular pump and the main process chamber. These gate valves allow for precise control of the vacuum system and can isolate the pump, protect the chamber, and adjust the pumping speed. The three positions of a typical 3-position gate valve are:1. Fully Open Position: Maximum conductance, full turbo pumping speed, used for initial evacuation or when maintaining high vacuum during deposition.2. Partially Open (Throttling Position): Purpose: In the partially open position, the gate valve is only partially open, throttling the conductance between the chamber and the turbo pump.Throttling is important when working with reactive gases (e.g., oxygen or nitrogen in reactive sputtering) or when you need to fine-tune the pressure for optimal film growth. This partially open position is manually set and adjusted one time during installation and can be changed anytime to run a different process condition. 3. Fully Closed Position: Purpose: In the fully closed position, the gate valve completely isolates the turbo pump from the main chamber. Use Case: This position is used to protect the turbo pump during processes like chamber venting, load-lock chamber sample loading, or when the chamber is being exposed to atmospheric pressure. It prevents contaminants or atmospheric air from entering the turbo pump, which could damage it.

Ideal Vacuum UltraLock High Vacuum HV Pneumatic Gate Valve ISO-F DN 630 Flange, Linkage Locking, Ball Type, Viton Seals, 304 Stainless Steel. ISO-630 Bolt Down Flange with M12 x 1.75 Threads. Includes Reed Switch Position Indicators These Ideal Vacuum UltraLock™ pneumatically operated gate valves have an ISO-F DN 630 vacuum flange with M12 x 1.75 blind-tapped holes. They are rated for high vacuum (HV) and follow vacuum technology standards as described in DIN 28404 and ISO 1609. These large pneumatically operated vacuum gate valves are built using a lever linkage locking mechanism which keeps the valve locked closed during loss of power or air pressure. These HV gate valves have a typical life of 20,000 cycles before needing service and are made with corrosion resistant 304 stainless-steel valve bodies and aluminum gates to reduce weight. These pneumatic gate valves include open and closed reed sensor switches which are mounted on the valve’s pneumatic cylinder. These switches can be used to activate indicator lights or used to control a more complex or automated vacuum protection system. UHV vs HV Versions: Our Conflat CF flanged gate valves are UHV rated. The bellows are welded to the bonnet plate, and oxygen-free, high-thermal conductivity (OFHC) copper sealing gaskets and flange knife-edges form the required metal-to-metal seal between the bonnet plate and valve body. Our Conflat UHV UltraLock valves have a low leak rate of < 3.75 x 10-10 Torr l/sec and are bakeable up to 200 °C with the gate open (150°C with the gate closed). Our KF and ISO-F flanged gate valves use Viton O-rings for the bellows and bonnet plate seals and are therefore limited to high-vacuum (HV) applications with ultimate pressures down to 3x10-8 Torr. KF and ISO-F series UltraLock valves have a leak rate of 1.5 x 10-9 Torr l/sec and are bakeable to 150 °C (with the valve open or closed). Solenoid Valves: We offer solenoid kits for our pneumatic valves in voltages of 12 VDC, 24 VDC, and 120 VAC. Solenoid kits are sold separately and include the solenoid valve, mounting bracket with fasteners used to attach the solenoid to the gate valve’s bonnet flange, and flexible 1/4” OD airlines to connect between the push-to-connect fittings on the gate valve’s pneumatic cylinder and the solenoid valve. Specifications: Our Ideal Vacuum UltraLock gate valves are designed for dependable High and Ultra- High Vacuum (UHV) applications and are often used in combination with cryo, turbo, and ion high vacuum pumps. Available sizes include Conflat CF 2.75, 4.5, 6, 8, 10, and 12 inch sizes; ISO-F DN -63, -100, -160, -200, -250, -320, -400, -500, and -630 sizes; and quick flanged sizes KF-40 and KF-50.
