Special Purpose Valves

OS, RV and MSV Series

High Performance in Specialized Applications


When a standard valve just won’t fit your project, our line of Special Purpose Valves can help. Each valve is designed for a specialized application:

  • One-shot (pulse) valve. The OS-1 is an air valve series that provides a momentary output at its cylinder port when pressure is applied at its inlet. This valve is commonly used in signal conversion applications.
  • Pressure sensing/sequence valve. The RV-1 Series valve is designed to open when a pre-set amount of pressure is applied to provide a pilot signal for circuit control.
  • Micro-limit valves. The MSV Series of valves are tiny, poppet-style valves designed for very light actuating forces.
  • Check and shuttle valves.
