EV Mouse Valves

Clippard's original EV series valve design is a deceptively simple arrangement featuring a remarkably quiet, low power operation. The Clippard "spider" armature spring is the only moving part, and its motion to operate the valve is a mere 0.007" travel. As a result, this valve features an exceptionally long life—proven to last more than 1,000,000,000+ cycles! Low voltage DC inputs move the spider, generating extremely fast response times of 5 to 10 milliseconds while using only 0.67 watts of power. The EV series is cool running and its compact, lightweight design makes it easy to mount in small spaces.

Standard Series

2-Way and 3-Way manifold and in-line mounting. Normally-Closed and fully-ported versions.

New! High Pressure Version

Clippard's high pressure EHV series valves are precision-built 2-Way control valves that accept low voltage, low current signals and convert them to high pressure (500 psig) pneumatic outputs.

Nickel-plated brass fitting

Electroless nickel-plated steel housing and core

Nitrile seals standard

Electroless nickel-plated brass body

Stainless steel stud and nozzle



Corrosion-Resistant Series

Clippard's Corrosion-Resistant Series incorporates materials and construction that provide enhanced protection for valves used with mildly corrosive media such as moisture in air or gases. Where stainless steel is not possible, plating is incorporated to add life to wear components. A nickel-plated brass valve body is standard, but stainless steel may be substituted.

Analytical Series

Clippard's Analytical series combines the proven features of the standard series with the specific needs of the analytical industry, and for applications where cleanliness is especially important. Special materials, manufacturing, and assembly processes make this valve perfectly suited for applications where internal cleanliness, bubble-tight operation, and long life are imperative.

Oxygen Clean Series

Most EV, ET, EC, and EW series electronic valves are available manufactured and assembled for use in oxygen-enriched environments for applications that are extremely sensitive to contamination. This involves:

• Ultrasonic cleaning, assembly, inspection, and testing in a clean room equipped with a state-of-the-art positive pressure HEPA filtration system and tested to exceed the ISO 13485 specification for medical devices.

• Removal of organic and inorganic contaminants, such as particulates and hydrocarbon oil

• No organic sealants, adhesives, or lubricants

• Component parts lubricated with oxygen-compatible PTFE grease (only as needed for assembly)

• Individual testing and inspection utilizing compressed nitrogen and ultra-violet light
