This 8 inch stainless steel reduced pressure zone backflow preventer assembly is designed to prevent the reverse flow of contaminated water of non-potable quality from being pumped or siphoned into the potable water supply due to backsiphonage and or backpressure. It is ideal for protection at cross-connections identified as health hazard applications and from other contaminants found at the service line entrance.

Features

• Stainless steel construction provides long-term corrosion resistance and maximum strength.
• The stainless steel body is half the weight of competitive designs, reducing installation and shipping costs.
• Short end-to-end dimensions make retrofitting easy.
• Cam-check assembly provides maximum flow at low pressure drop.
• No special tools required for servicing.
• Compact construction allows for smaller enclosures.
• Stainless steel relief valve features a balanced rolling diaphragm to eliminate sliding seals and lower maintenance costs.
• Equipped with domestic non-rising stem resilient seated gate valves.
• Includes a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve.
• The flood sensor is installed on the assembly exterior and relays a signal to trigger notification to facility personnel.
• An add-on connection kit is required to activate the flood sensor's alert feature. Without the connection kit, the flood sensor is a passive component that has no communication with any any other device.
