375 Bypass Valve

375 Bypass Valve

The new Lee 375 Bypass Valve is designed to shunt flow across an actuator piston when the system pressure is either shut off or lost. The 375 Bypass Valve is normally open device, with a hydraulically-actuated pilot-to-close feature.

This miniature valve weighs only 16 grams and is designed for 4000psi systems. The metal components are constructed entirely of stainless steel for durability and long life. Each Lee Bypass Valve is 100% tested and inspected to ensure reliable, consistent performance.

250 PRI Pressure Relief Valve

250 PRI Pressure Relief Valve

The new 250 PRI pressure relief valve is the latest addi­tion to Lee’s line of miniature pressure relief valve inserts. This new valve is ideally suited for low flow hydraulic applications where a miniature, light weight pressure relief valve is needed. The 250 PRI is only 1.1 inches long and weighs only 4.5 grams. A Lee Safety Screen is incorporated at the inlet of the valve for protection.

Available in forward and reverse relief flow configurations, the 250 PRI is available in a wide range of standard cracking pressures from 80 to 3600 psid, and is constructed entirely of stainless steel for durability and long life. Each 250 PRI is 100% tested and inspected to ensure reliable, consistent performance.

Quiet Operation 3 Way Solenoid Valve

Quiet Operation 3 Way Solenoid Valve 

The Lee Company’s new Quiet Operation High Density Interface (HDI) is a 3-way solenoid valve designed to achieve patient comfort by reducing actuation noise by 50%. A typical solenoid valve has an inherent clicking sound when energized, which is caused by the metal-to-metal contact of the moving armature and stationary core. This new quiet operation design uses “whisper” technology to provide a sound level measurement of less than 37 dBA when measured at a distance of 24 inches and a valve cycle frequency of 10 Hz. Available in face mount, plug-in and ported configurations, the Quiet Operation HDI is ideal for medical applications flowing gas or air, such as dialysis machines, patient monitors, ventilators/respirators and other bedside medical devices.

Lo Lohm HDI Solenoid Valve

Lo Lohm HDI Solenoid Valve 

The Lee Company’s High Density Inter­face (HDI) solenoid valve has been improved by offering more flow capacity without sacrificing size and weight. The Lo Lohm HDI solenoid valve provides the features of a large valve coupled with the superior performance of a miniature valve in one compact design. A spike and hold voltage drive is used to achieve an extended flow and pressure range. Performance parameters can be optimized for a specific application.

Manual Override Solenoid Valve

Manual Override Solenoid Valve

A new solenoid valve has been developed which has a manual override capability for typical applications in engine cowl door systems and cargo door actuators on commercial aircraft and in rotor blade fold units on military helicopters. Currently available in a single coil normally closed configuration for 4,000psig systems, the valve can be designed with single or dual coils in normally closed or normally open configurations for operation in 3,000 or 5,000 psi systems .

Atomizing Nozzles Offer Precise Spray Pattern

Atomizing Nozzles Offer Precise Spray Pattern

The new atomizing nozzles, available in both airless and air-assisted styles, generate a 50-degree hollow cone spray pattern and offer precise, controlled atomization in a compact package. The airless atomizing nozzles do not require an external air supply and will atomize with pressures as low as 20 psi (on water).

Available in multiple flow ranges, the nozzles can be installed directly onto a proprietary VHS micro-dispense solenoid valve for precise flow control using pulse-width modulation (PWM).

Atomizing Nozzle Spray

 

The air-assisted nozzles utilize an external air source to control the atomization, allowing lower operating pressures (5 psi). The pressure of the liquid and air can be independently controlled to fine-tune the flow rate and nozzle performance.

Atomizing nozzles with special mounting configurations and PEEK wetted materials are available upon request.

CB Solenoid Valve

CB Solenoid Valve

The new Lee CB Solenoid Valve is economically designed, utilizing a cartridge bobbin coil coupled with our unique MultiSeal™ technology. The MultiSeal radically simplifies port layout by allowing total porting flexibility 360° around the seal, without the need for O-Rings or anti-Extrusion Rings. Weighing just 0.16 pounds, the CB Solenoid valve is a 3 way, normally closed design that is offered in both single coil and dual coil configurations with the lead wires exiting at either end of the valve and it will flow 0.31 USGPM at 3000psid .
