• It prevent the reverse flow of hot or cold polluted water from entering into the potable water supply
• It consists of a brass body with stainless steel internal parts, integral strainer, and two durable, tight-sealing, rubber check valves
• For continuous pressure, non-health hazard applications in smaller supply lines
• It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing
• A secondary check valve utilizes a rubber disc-to-metal seating
• In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system
• True line-sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling
• Maximum flow at low pressure drop
• Furnished with union connections to facilitate removal and replacement for maintenance
• Compact for economy combined with performance
• Design simplicity for easy maintenance
• Can be installed vertically or horizontally
