Proportional Valve Design Meets Control System Challenges

From Clippard Instrument Laboratory, Inc.
 

 
Clippard Instrument Laboratory, long a pioneer in the miniature pneumatic industry, has achieved a breakthough in proportional valve technology with the introduction of the EVP series proportional valve. Since 1974, Clippard (clippard.com) has produced the EV series valve, said to combine simplicity of design, low power, fast operation and long life (applications have exceeded 3 billion cycles with a single valve), resulting in one of the most successful and reliable products in its 60+ year history. The heart of the valve is the armature, which is the valve's only moving part. Dubbed the 'spider' because of its flexing 'legs,' it has contributed to make the EV valve both very reliable and versatile. This valve has been used in thousands of applications by OEMs with exacting requirements.
Products & Services
Water valves are designed to handle and control hot water, cold water, ground water, potable water, salt water and/or wastewater. They are made from metal or plastic. Search by Specification | Learn more about Water Valves
Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves. Search by Specification | Learn more about Hydraulic Valves
Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Search by Specification | Learn more about Gas Valves
Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices. Search by Specification | Learn more about Air Valves
