The Lee Shuttle Valve is supplied in four configurations and is designed to isolate the normal from the emergency hydraulic system during normal operation.
Configurations include: a spring based shuttle valve with the emergency port normally closed, the detented shuttle valve which features a poppet latch to close off either the emergency port or the normal port, selective shuttle valves with a non-biased, loose ball design, and inverse shuttle valves where the lower pressure inlet port is open to the common port instead of the higher pressure inlet port.
Lee Shuttle Valves feature miniature insert fits in the head of the actuator, non-interflow design, and low leakage or zero leakage.

We provide Lee Checks in a range of sizes and as forward or reverse flow, side exit, zero leak, or pilot operated versions and are supplied in three basic configurations. We supply Lo-LOHM Checks (poppet-style, high flow-gain check valves that are wide open at 15 psid and offer the lowest Lohm rate), Hi-Q Checks (offer the greatest feasible flow capacity for valve cartridges between ½ and 1inch in diameter), High Pressure Checks (poppet-style valves for up to 8000 psi systems),and Pilot Operated Checks (an all metal pressure piloted to open check valve).
The ultra compact Lee Piloting Solenoid Valve was designed and manufactured for use in aerospace hydraulic and fuel systems, oil tool applications, and other related high pressure applications.
The valve features high performance properties (efficient force/stroke relationship), low power consumption, normally closed and normally open valves for 3000, 4000, and 5000 psi, single
coil and dual coil configurations, multiple lead wire egress options, and integral connectors.

Alongside our extensive catalogue of mini and micro flow components we are also able to design and manufacture an equally comprehensive array of bespoke solutions. We understand that our customers’ applications are unique and as such approximately half of the the products we deliver are either adaptations of our standard products, for example tweaking certain elements of the product such as cracking pressure or leakage, or completely bespoke components that have been designed to meet our customers’ exact specifications. Please contact us so we can discuss your requirements in detail.
We are proud to have created many pioneering components during the years that have proved essential for use in many industries. In the 1960s we created the Lee Interface Fluidic (LIF) solenoid valves to meet high performance and reliability demands of the industry. Since the development and success of this first electro-fluidic system, we have designed and created a range of fluid components that are suitable for complete systems for flowing all kinds of fluids and gases.
Please contact us for advice and information on how to build complete fluid handling systems using our highly accurate and reliable components.
Our range of solenoid control valves includes both 2 and 3-port varieties, suitable for the control of air, gases and mild liquids. The valves themselves are compact, efficient and designed with low power consumption in mind. Featuring a small but effective build, these valves offer the ideal solution for applications where space is limited. Customers can choose from different series, including LGV, LHD, LHL and LHQ, with options to suit everyone.
Our dispensing valves have been designed to control the flow of small amounts fluid at high-speeds. Lee Products’ VHS series of dispensing valves are popular for medical and scientific applications where the dispensing of fluid in microliters and nanoliters is required. Designed to deliver enduring performance, these solenoid valves can be adapted to meet the demands of your unique application.
Our INK series of solenoid valves delivers high performance and high speed ink dispensing for large character printing applications. These drop-on-demand dispensing and low power consumption valves are available with customisable options to suit your individual application.
Lee Products offers a comprehensive portfolio of HDI platform control valves that are designed to be utilised in applications that require controlled movement of air, gas or mild liquids. We have three solenoid valve designs to choose from:
For each design you can also select from plug-in or face mounting styles, with 3-port designs also offering the option of ported mounting.
Our fixed volume dispense pumps are positive displacement pumps, which are solenoid driven. They benefit from a compact, lightweight design and can dispense volumes with great accuracy and repeatability. Fixed volume dispense pumps are normally utilised within the medical industry and therefore safety and reliability is key. Fortunately, we thoroughly test all our pumps prior to making them available to buy. We also utilise durable, chemically inert materials, ensuring our products are long-lasting and resistant to damage.
We offer a variety of variable volume dispense pumps which utilise stepper motor technology in order to achieve positive displacement. The pumps themselves benefit from a compact, lightweight, maintenance-free design, ensuring they can be positioned anywhere they may be needed. All of our variable volume dispense pumps are offered as standard or high performance, with models to suit every need. Customers can be assured that this range offers exceptional accuracy, reliability and performance.
We began working in the field of electromechanical valve and pump technology more than three decades ago, swiftly becoming an industry leader. We have a wealth of experience with manifold technology which has several distinct advantages when compared to systems where discrete components are connected with just tubing. The number of leakage points is reduced and lower internal volumes are achieved. Manifolds offer a higher level of flexibility and are more easily assembled into the instrument. There are several different manufacturing techniques involved, including conventional, multi-layered, ant farm, combination and injection manifold. Our expertise in fluidics means we have a thorough knowledge of all the different techniques and understand both the components used, as well as the application they are to be used in. There is a good deal more information about manifold technology on our website, so do have a look.
Our Visco-Jet micro mixer utilises cutting edge aerospace technology, allowing for effective and efficient static mixing. Thanks to an innovative design, the components utilise the liquids themselves in order facilitate the mixing and therefore do not require any external mechanical or electrical input. The liquids are mixed using 36 controlled spin chambers, ensuring effective and reliable results. Customers can visit the website for further information on this or any of our product ranges.
MINSTAC stands for Miniature Inert System of Tubing and Components and it has been designed for use in conjunction with aggressive fluids. Lee Products has created a tube end solution that avoids the potential damage caused by these fluids at vulnerable connection points. This is accomplished with our specially designed Collet-Lock system, which creates a leak-proof connection between PTFE tubing and our MINSTAC components. We offer various standard tubing assemblies as well as fitting assembly tool kits.
