• in Solenoid Valves

  Lee is a family operation manufacturing solenoid control and solenoid inert valves for fluid handling systems. Solenoid control valves feature small size with a life cycle of over 200 million cycles. These valves are often customized to meet OEM requirements. Types include 2-way piloting (non-inert), 3-way, 3-way (non-inert) and 3-way latching (non-inert). Solenoid inert valves are used in medical and scientific instrumentation applications where contamination is the main concern. These valves are also designed for OEM requirements. Types include 2-way, 2-way with injection port, 3-way, and 3-way for low turbulence.
