Description

The Zurn Wilkins Model 375ADA 2 1/2 inch Reduced Pressure Detector Assembly is a critical backflow preventer for fire protection systems. It safeguards potable water supplies from contamination caused by backsiphonage and back-pressure. Featuring an epoxy coated ductile iron body and grooved connections for steel pipe, this assembly includes a metered by-pass to identify leaks and unauthorized water use. It operates up to 175 PSI and is designed without integral gate valves. This unit is ASSE, CSA B64.4, AWWA, UL, and FM approved, ensuring reliable performance in high-hazard applications. Item number 212-375ADAL.

Help Me Connect

This Zurn Wilkins Model 375ADA Reduced Pressure Detector Assembly is configured with grooved connections on both the inlet and outlet. These connections are designed for use with steel pipe and require compatible grooved couplings for proper installation. This specific model ships less shut-off valves, meaning external shut-off valves will need to be installed on both sides of the assembly if required by local codes or application needs.

FAQs

What is the primary purpose of the Zurn Wilkins Model 375ADA?

The primary purpose is to protect potable water supplies from contamination in fire protection systems by preventing both backsiphonage and back-pressure. It ensures that contaminated water cannot flow back into the clean water supply.

What type of connections does this 2 1/2 inch model have?

This model features grooved connections on both the inlet and outlet. These connections are designed for easy installation with steel pipe using compatible grooved couplings.

Does this specific 2 1/2 inch 375ADA model include gate valves?

No, this model is specified as 'less shut-off valves' or 'less gate valves' and does not come with integral shut-off valves. External shut-off valves would need to be installed separately if required for the application.

What is the maximum operating pressure and temperature for this device?

The maximum working water pressure for this assembly is 175 PSI. The maximum working water temperature it can handle is 140°F.

What material is the main valve body made from?

The main valve body is constructed from ductile iron, meeting ASTM A536 standards, and is finished with an NSF Approved fusion epoxy coating for durability and protection.
