The atmosphere admitted to the system breaks the vacuum, preventing the collapse of the storage tank. It is recommended that the VR20 be installed in an upright position.The VR20 also features a low-profile design with a slotted vent hole. Circular dust protects the vent hole cover approximately 1.75" in diameter. This valve features an all-brass body and body cap, a heat-resistant silicone seat disc, an integral body seat, and brass internal working parts.
