Safe dispensing of heated material in volume

An Integrated Dispensing Systems product story

The 2200-806-003 No-Drip dispense valve from Integrated Dispensing Systems is specifically designed to allow the safe and efficient dispensing of heated material in a high volume environment

The 2200-806-003 No-Drip dispense valve from Integrated Dispensing Systems is specifically designed to allow the safe and efficient dispensing of heated material in a high volume manufacturing environment such as packaging or ballast manufacturing.

The manufacturers, Sealant Equipment and Engineering of Plymouth, Michigan, had two challenges to meet when designing this valve.

Firstly, packaging applications demanded high volume dispensing coupled with a crisp, immediate shut-off as dripping material between packages is unacceptable.

Secondly, ballast manufacturing utilising heated 'pitch' demanded a high volume delivery, a fast shut-off with the elimination of splashing and dripping, and a good resistance to the abrasive nature of the material.

The resultant 2200-806-003 valve addresses these needs and enables full control of the dispense operation.

The double acting, air operated valve, with its wear resistant carbide ball and seat, has an instantaneous opening and closing action coupled with a No-Drip design zero-cavity nozzle, thereby eliminating any splashing and run-on of heated material when dispensing is stopped.

This has made the job safe for the operator and precise for high quality product output.

Available with handles for hand operation or without for fixture mounting.

The valve's 1" NPTF material inlet port and >" diameter zero-cavity outlet port ensure high material flow rates.

A second 1" inlet port is included, allowing valves to be 'ganged' in series (for multiple dispense stations) or for recirculating material back to the tank, thereby preventing filler settlement.

The aluminium valve body is heated with (4) cartridge heaters, monitored by a 'J' type thermocouple.

An additional band heater and thermocouple are located around the nozzle enabling materials to be heated up to a temperature of 450*F (232*C) at a maximum pressure of 4000 psi.

The divorced design, via phenolic spacers, ensures that the material and high temperatures do not come in contact with the air cylinder.

The valve's carbide hardened components and wear resistant, high temperature internal seal compensate for the abrasive nature of the materials while still remaining effective at the high operating temperatures.
