Agilent vacuum pump isolation (VPI) valves are inlet protection valves that electrically connect with the mechanical pump. The valves close rapidly when power is interrupted to prevent oil backstreaming or particle migration into the vacuum system. They also vent the pump from the inlet side, pushing any debris towards the outlet, and preventing it from being swept into the system when pumping is restarted.

The LSP Series are 2-way, normally closed, high flow solenoid valves for applications requiring a particle tolerant flow path. The LSP Series valve is a 2-way, manifold mounted, normally closed design featuring a full bore flow path. The full bore allows unimpeded high flow and is very tolerant of fluids that have particles and solids. The design minimizes clogging and leakage in applications such as waste and drain lines.…

Agilent direct acting Electromagnetic Block Valves eliminate the need for compressed air in a wide variety of vacuum applications. These normally closed valves are compact, maintenance-free and have a service life of 250,000 cycles. EMBVs are available with NW16 or NW25 connecting flanges, and with finished aluminum or nickel-plated bodies, for mildly corrosive applications. Multiple voltage compatibility options are availabl…

Agilent is pleased to offer Series 12 aluminum gate valves in partnership with VAT. The Series 12 valves provide a cost effective, low-particle, low-profile means of isolating a high-vacuum pump, and are a less expensive alternative to stainless steel valves. Series 12 valves are clean, economical, and smoothly actuated.

Agilent’s family of vacuum Stainless Steel Tube Valves are designed to connect our rough vacuum and high vacuum pumps to your system. Delivering maximum conductance and sized for easy, convenient installation, these valves are ideally suited for systems requiring high reliability with low outgassing. 

Agilent is pleased to offer the all-metal UHV Series 54 valves in partnership with VAT, which are suitable for extreme, ultrahigh vacuum (UHV/XHV). They can be manually operated with a standard hex wrench, so no torque wrench is required.

The Agilent Variable Leak Valve includes a movable piston with an optically flat sapphire that meets a captured metal gasket. This forms a seal completely free from friction, seizing, and shear. The sapphire’s movement is controlled through a threaded shaft-and-lever mechanism that provides a mechanical advantage of 13,000 to 1. 

2 and 3-way solenoid valves used to control the flow of liquids and gases. With these kinds of valves, the fluid is in contact with the valve's metal plunger.   LHD SERIES SOLENOID VALVES Lee's High Density Interface (LHD Series) Solenoid Valves are designed for applications where space is limited. Featuring small size and light weight without sacrificing performance and reliability, the valves are available in three…

2-way, high speed valves used to dispense small amounts of fluids.   VHS SERIES SOLENOID VALVES The Lee VHS valves are high speed, 2-way solenoid operated valves designed for applications requiring microliter and nanoliter dispense volumes. These applications include high throughput screening and drug discovery. The VHS valves feature: High speed operation: up to 1200 Hz Long life: 250 million cycles minimu…

2 and 3-way valves that separate the working fluid (or gas) from the metal components of the valve. These are typically used with more aggressive liquids.   LFV SERIES SOLENOID VALVES The LFV Series is a family of 2-way isolation valves, featuring bi-directional flow and a contoured flow path which allows complete flushing. This contoured flow path also minimizes damage to "delicate" fluids. The small internal volume…

Lee offers a wide range of nozzles capable of providing either a precise droplet or atomized fluid. Several mounting styles allow these nozzles to be incorporated directly onto our VHS dispensing valves, or to be connected to valves using soft flexible tubing. Dispense nozzles are available in straight tubes or with jeweled orifices (allowing tighter droplet control). Mounting styles include: 062 MINSTAC 062 MINS…

The Lee Series 120 Solenoid Valve is a 2-way, ultra-miniature, magnetically latched solenoid valve ideal for compact battery-powered pneumatic applications such as air piloting, lab automation (lab-on-a-chip), and other miniature, power-sensitive markets such as fuel cells or for R&D proof of concept projects. The Series 120 valve sets a new industry standard in reducing space, weight and power consumption. Measuring just 0…

The Lee IEP Series valves are 2-way, extended performance, axial-flow solenoid operated valves. These are designed for high pressure and high temperature applications where small size and lightweight are critical factors. The IEP Series valves are supplied with 1/16" inlet and outlet stainless steel tubing. This allows the valve to be connected using standard high pressure chromatography fittings or welded directly in place…

The ASCO Series 038 miniature solenoid valves offer isolated fluid control and are designed for use with neutral or aggressive liquids in clinical diagnostic instruments.
