Modular Valve Line Overview

Modular Valves are quite simple compared to other pneumatic components when you examine the elements that make up the line of products.  Essentially there are only 3 base valves and 18 different ways to actuate the base valve.  These combinations give a variety of versatile valve elements that broaden the possibilities when designing a pneumatic circuit.  These valves are the ideal manifold mounted solution to pneumatic circuit applications.

Modular Series Base Valves

Can be used as a:
• 2-way normally closed valve
• 2-way normally open valve
• 3-way normally closed valve
• 3-way normally open valve
• 3-way diverter valve
• 3-way selector valve
Can be used as a:
• 4-way fully ported valve
• Dual 2-way valves
 (one N.O. & one N.C.)
• Dual 3-way valves with common exhaust
 (one N.O. & one N.C.)
Can be used as a:
• 6-way fully ported valve
• Dual 2-way normally closed valve
• Dual 2-way normally open valve
• Dual 3-way normally closed valve
• Dual 3-way normally open valve
• Dual selector valve
* R-436 and R-421 are exceptions to the Basic 3  

Key Points to the Modular Line:

  • All Valves are Universally Ported
        (There is not a required direction 
           for flow through the valve ports)

  • Use Any Compatibles Fluid 
  • Flow is 9 SCFM at 100 PSIG
            (255 lpm at 6.9 bar)

  • Vacuum to 150 PSI
  • Balanced Spool Design 
  • All Valves are Keyed to manifold 
  • Valves are interchangeable to alter
     functions and features of circuit


Key Points to Actuator Methods:

  • Each Valve needs 2 Actuators

  • Not all Actuators can be combined
    on same valve   (8 ports max)

  • Minimum Pressure for Pilots:
     With Spring = 40 PSIG Minimum
     Without  Spring = 20 PSIG Minimum
     Lower pressure pilots available

Here is where the flexibility for design and versatility of function come in:   Combine your base valve with 2 of the following.

Example:  An Auxiliary Pilot and Single Air Pilot combined with a 3-Way base valve give you the R-301
