Series 400 Autovalve

With meter mix systems and fluid dispensing systems, the Series 400 is a reliable and durable pneumatic autovalve, built with Teflon® seals that reduce maintenance in the shut-off area. The retraction of the shafts allows for higher flow rates of A & B components.


  • Easy to Clean: If cross contamination occurs, the manifold can be removed and cleaned without disassembly of the valve body
  • Optional Stainless Steel Valve: Recommended for corrosive acrylics or epoxies
  • Flush Valve Manifold: For cleaning the mixing nozzle with air or solvent. A check valve is threaded into the side of the manifold
  • Lubricated and Hard Coated Pistons: Lubricated with Nordson EFD Autogrease for moisture sensitive adhesives and hard-coated to resist abrasive adhesives
  • Optional Polytuff, PTFE, Viton® and EP Seals: For varying chemical formulations and abrasive conditions
  • Optional Night Cap Ratio Check Cap: Available for 1:1 ratio manifold

Ordering Guide

  • Valve, manifold, and handle must be ordered for complete assembly
  • Optional pistol grip handles and swivel base are available
  • For high back pressure conditions (i.e., over 1,000 psi/69 bar) order a double air cylinder
  • Seal Designation: T=PTFE; P=Polyurethane; V=Viton®, G=Polytuff

Series 400HF Autovalve

The 400HF Valve provides flow rates that are 15-30% greater than the standard 400 Valve configuration, without compromising accuracy or consistency. The large ¾" material inlet ports permit flow rates of 4-5 gallons per minute, depending on pump capability and material viscosity.


  • Weight (Al Valve and Manifold): 1.6 lbs (0.7kg)
  • Weight (SS Valve and Manifold): 2.5lbs (1.1 kg)
  • Pressure Rating: 3,500 psi (240 bar)
  • Flow rate: 3-4 gallons per minute (Series 400);
                     4-5 gallons per minutes (Series 400HF)
