Solenoid Valves

Solenoid Valves for Oil and Gas

A New Benchmark in Space and Weight Savings

Lee miniature piloting solenoid valves combine space and weight savings with superior performance and reliability in demanding applications. That is why industry leaders have been successfully using them in directional drilling, coring tools, intervention tools, packers, toe sleeves, subsea control pods, and ROVs for decades. Lee solenoid valves have set a new benchmark in space savings and power consumption by incorporating an innovative coil design and the Lee MultiSeal®. The smallest version is less than 0.875 of an inch in diameter and uses only 7.8 Watts at 28 Vdc.

The Lee MultiSeal® is a sealing concept based on the controlled expansion of a cylindrical polyamide-imide element that eliminates conventional O-rings. This simplifies porting layout and offers significant space savings. Before delivery, each valve endures rigorous acceptance testing to ensure its performance and reliability. Therefore, Lee solenoid valves may represent a departure from traditional solenoid designs, but they’ll never represent a risk.

Although The Lee Company offers a broad line of solenoid valves, we frequently provide custom solutions. Fortunately, our custom designs are as reliable as our standard models. The Lee Company is vertically integrated, owning the entire production process throughout the life of our components, down to the smallest detail – we even wind our own coils. This level of vertical integration lets us create customized valves with unique electrical requirements, flow rates, pressure conditions, leakage rates, hydraulic interfaces, and more. Specific to the Oil and Gas Industry, we can supply NACE compliant solenoid valves rated up to 10,000psid and 400F in a package as small as 0.55 inches in diamater.

Lee Miniature Piloting Solenoid Valves

Lee miniature piloting solenoid valves are the most compact powered components we offer, available in a configuration just 0.875 of an inch in diameter and weighing less than 0.14 lbs. Their threaded bodies are easy to install and maintain, and they are available for system pressures up to 5000 psi. Meanwhile, the efficient coil design requires power levels as low as 7.8 Watts at 28 Vdc. Many options are available, including a single or dual coil configuration, 2-way or 3-way porting, a normally open or normally closed position, and a customizable electrical interface.

360° Porting Piloting Solenoid Valves

These configurations incorporate the same advantages as our standard solenoid valves in terms of weight and compactness. Still, their unique MultiSeal® design provides omnidirectional porting, allowing greater flexibility and potential weight savings when designing the housing. These valves are also available in all our different configurations, including a single or dual coil configuration, a normally open or normally closed position, and a lead wire front, lead wire rear, or connector.

Zero Leak Solenoid Valves

In applications where zero leakage is critical, this design incorporates a polyamide-imide seal that’s leak-tight in a one-minute test using clean, dry nitrogen. Otherwise, this component retains all the advantages of a standard Lee miniature piloting solenoid valve. It’s available standard in a single-coil package for 3000 psi operating systems. Custom configurations optimized for higher operating pressures or wide operating pressure ranges are available upon request.

Latching Solenoid Valves

Lee latching solenoid valves are the ideal solution for power-sensitive applications. By incorporating permanent magnets into the coil design, these solenoid valves offer a dramatic reduction in overall power consumption, mainly when operating with extended “ON” periods. Unlike traditional designs that require continuous voltage to energize the valve from its natural state, these latching solenoid valves need only a momentary pulse of less than a Joule to switch to and remain in state. The Lee Company also offers a NACE-compliant version of the latching valve for applications requiring increased corrosion resistance.

High Flow Solenoid Valves

Our high flow solenoid valves are available in 2-way, 200 Lohms, and 3-way, 300 Lohms configurations for more demanding applications. Both are two-stage poppet designs in a small package. These valves are available in normally open and normally closed and single or dual coil configurations for 3000 psi system pressures.
