The VR-801 VAC uum relief valve is designed to protect hot water supply systems and pressure vessels against negative pressure. It is especially well suited for many domestic and commercial systems. It works by preventing internal VAC uum conditions that could result in burned out heaters and/or collapsed storage tanks. Installed on the cold water supply line, the Cash Acme VR-801 closes tightly under pressure and opens at a 1" mercury VAC uum. Atmosphere admitted to the system breaks the VAC uum, preventing collapse of the storage tank.
  • Drilled vent with dust cover
  • Prevents internal VAC uum conditions - guards against siphonage, burnt-out heaters and collapsing of storage tanks and negative pressure
  • Opens quickly in emergency situations on a one" mercury VAC uum
  • Every valve is tested for performance prior to shipping
  • Water service
  • 1" Hg VAC uum relief pressure open
  • Brass body cap and internal parts
  • Stainless steel spring
  • Polypropylene dust cover
