Peter Paul produces an extensive line of solenoid valves. Peter Paul series 20, 30 and 70 solenoid valves feature two way normally open and closed, three way normally open and closed, three way directional control and three way multi-purpose configurations. Solenoid valves are available in brass, stainless steel and plastic bodies. High pressure valves consist of bubble tight sealing, psi up to 3000 and designs including two way normally open, two way normally closed and three way normally closed. Peter Paul series 50, 15 and 58 of miniature solenoid valves are available in 2 and 3 way constructions, in brass and stainless steel materials, and also in screw-in or cavity manifold configurations.

Gems Sensors & Controls provides solenoid valves with 2 way, 3 way normally closed, 3 way normally open, 3 way multipurpose and 3 way directional control configurations. Selection of solenoid valves includes A series, B series, D series, Chem-S, BS series, M series, EH series, GH series, B Cryo series and D Cryo series. Body materials include 303 stainless steel, Isoplast, polypropylene, brass, nickel plated brass and 430F stainless steel. Fluid connections includes 1/8" NPT, 1/4" NPT, and 1/8" barb fittings. Seal and O-ring materials include Viton, Rulon/Viton and Rulon/Variseal.

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.

Manufacturing micro solenoid valves is Farmington Engineering's specialty. They offer a 2-way/2-position solenoid valve in a normally closed (N.C.), manifold mount configuration, suitable for shutting off liquid and gaseous fluids. A 3-way/2-position solenoid valve in a normally closed, 10-32 configuration is available for plumbing, medical/dental, beverage and steam applications. Farmington also manufactures a 3-way/2-position solenoid valve in a normally closed, manifold mount configuration.
