This is a manually operated 180° in-line Ideal Vacuum Super-Seal bellows valve with Conflat CF 1.33" (1-1/3") flanges on the inlet and outlet ports. Conflat flanged Super-Seal valves have rotatable flanges for optimal connectivity to vacuum lines. This valve is rated for high-vacuum use (10 Torr) and can be used up to the 60-80 psig positive pressure range. These Super-Seal valves have a leak rate of 10 Torr l/s (He). All high-vacuum rated Super-Seal valves use 304L stainless steel for the valve body and mechanism, and Viton® bonnet and poppet seal O-rings. These valves operate with low friction and zero abrasion of the polymer elastomer surface allowing for repeatable sealing action over many thousands of cycles. Super-Seal valves provide high-conductance to maximize the evacuated gas flow rate. These valves are bakeable up to 150°C (limited by the Viton O-rings) and can withstand a maximum differential pressure of up to 15 psig. They can be mounted in any orientation.

In the simplest of terms, VAT pnematic 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 VAT 91 Series Pneumatic Gate Valves feature a wedge shape gate design. The gate seal is pressed against the sealing surface by means of a pneumatic actuator. Shock and vibration are reduced to a minimum by a unique air cylinder design. This feature is extremely beneficial for demanding pump isolation applications, especially those with high levels of process byproduct in the gas stream

The Edwards IPVEK In-Line Solenoid Vacuum Valves are compact, lightweight and designed for low energy consumption. These Valves are great for use in vacuum pipeline systems down to 1 x 10 mbar. The valve mechanism is a moving pole and bellows assembly operated by the solenoid. The pole is enclosed in an iron casing and the bellows assembly is hosued in the lower vacuum body, isolating the valve mechanism from the system. With an improved circuit board design, the life expectancy of the Edwards IPVEK In-Line solenoid valve is greatly improved and will function virtually maintenance free up to 130,000 cycles.

This Pfeiffer Stainless Steel Pressure Relief Valve protects vacuum systems from over pressure. It has KF-16 fittings on both the inlet and outlet ends. An exhaust hose can be attached to the KF16 connection at the outlet side. Measuring just 30mm in diameter and 25mm in height, this compact Pfeiffer Pressure Relief Valve has a leak rate of less than 1 x 10-8 mbar l/s, a temperature range from 41-140°F (5-60° C), and opens with a pressure differential of approximately 300 Torr. It is intended to be used for vacuum chambers only.

These Brand New MKS Instruments KF16 Bellows Angle SERIES 150 Valves are designed to insure product quality, reliability and value. These function reliably in applications ranging from semiconductor manufacturing to plasma physics research to nuclear accelerators. These angle valves are primarily for vacuum processes. Sometimes the valves encounter pressures above atmospheric in gas handling, or in backfilled systems. These MKS Instruments valves may be used over the pressure range from atmosphere to below 10-9 Torr. The bellows design and closing force provide reliable operation to the maximum pressures stated. A single acting cylinder opens the pneumatic valves up through the 3 inch size. When the cylinder is vented, a strong spring closes the valve. The spring within the bellows acts directly upon the nose-piece. Upon failure of the electric control voltage to the solenoid coil or upon failure of the pneumatic supply, the valve fails closed. Valves in the 4 inch size are available either with (V-100 series) or without (150 series) a closing spring, and 6 inch valves are only available without a closing spring. Valves without a closing spring have double acting cylinders. In all sizes the pneumatic cylinder is lubricated adequately for the service life of the valve.

The SECUVAC safety solenoid right angle valves come in a range of operating votages and flange types. The valve for sale here is a KF16 right angle valve that is made to operate at 100-115VAC. These solenoid right angle valves were specially developed for use with rotary vane, dry scroll, semiconductor, and roots blower packages which are not equipped with a built-in anti-suckback valve. The SECUVAC safety valve protects the vacuum system against unplanned venting via the backing pump in case of a power failure and it ensures that the vacuum system remains sealed until the backing pump, after it has restarted, has evacuated the connecting lines. Immediate closing action upon power failure. Opening action only after the in-take line has been evacuated. This valve is designed to operate down to 10-9 mbar / 7.7 x 10-10 Torr and up to a pressure of 2100 mbar / 1575 Torr (30psi).

These NEW Edwards IPV16MKA Manual Inline Lever Operation Bellows Isolation Valves are very quick acting.
