Spartan Scientific offers a selection of solenoid valves , solenoid operators, diaphragm process valves, air piloted solenoid valves, direct acting solenoid valves, media separated valves and drain valves. Solenoid operators of Series 2500, 3800 and 4000 includes sub-micro solenoid operators and solenoid operators suited for 3 and 4 way pneumatic directional control, spool valves and directional control valves. Spartan's diaphragm valves have a port range of 1/8 to 2 inches and materials of brass and stainless steel. Spartan's air piloted valves have a port range of 1/4 to 2 inches and various valve designs.

Clippard supplies a line of solenoid valves in multiple designs and model types. Solenoid valves include 1/8 and 1/4 inch NPT direct acting 2-way solenoid valves, 1/8 inch NPT direct acting 2-way stacking solenoid valves, 1/8, 1/4, 3/8, and 1/2 inch 3 way solenoid valves, 1/8, 1/4, 3/8, and 1/2 inch NPT 3 way double solenoid valves, 1/8 and 1/4 inch NPT direct acting 3 way double solenoid valves, 3/8 and 1/2 inch 5 port 4-way double solenoid valves, 1/8, 1/4, and 3/8 inch 5 port 4-way single solenoid valves.

Target Rock manufactures solenoid operated isolation valves for containment isolation, sampling, reactor head vent and power operated relief valve applications. Specs include sizes from 3/8 in. to 6 in (150 mm), pressures to 2500 psi (17 MPa), 48 VDC to 220 VAC, and IEEE 323, IEEE 344, ASME III, ASME QME-1. These solenoid operated isolation valves are smaller and lighter than motor or air operated valves, and require lower power (no three phase power cable or motor control centers).

Parker manufactures the VA01 Series solenoid valve for centralized vacuum systems. Their FSV Series flow sensing valves assist in maintaining an acceptable vacuum level in the vacuum system if vacuum cup does not make a proper seal. Their CH Series check valves are used to hold a degree of vacuum when the vacuum generator is turned off.
