Dispensing Valves


Constant Bead Valve

The 800RV is a constant-bead, dispense valve. Designed to deliver a uniform bead dimension irrespective of any air pressure build-up at the opening of the valve and at the start of the bead. This neutralizing pressure feature ensures a perfect bead with a clean cut-off of the material at the end of the bead path.

Suitable for medium to high viscosity materials such as silicone, RTV, sealant and grease. The valve is available as model 800RV-LL with a Luer lock fluid outlet and as 800RV-N with 1/4” NPT fluid outlet.

4-Way Valve Operation

The 800RV is a two-stage pressure isolation valve. Applying a minimum of 60 psi to the air inlet will cause the valve to open and dispense the material. 

The valve is controlled by a 4-way valve controller - VC1195N, which will control the opening and closing of the valve. 


  • Suitable for high viscosity fluids
  • Constant uniform bead dispensing
  • Close tolerance
