Specifications

2000SS - The double check valve assembly shall consist of two independently operated spring loaded cam-check valves, required test cocks, and optional inlet and outlet resilient wedge shut-off valves. Each cam check shall be internally loaded and provide a positive drip tight closure against the reverse flow of liquid caused by backsiphonage or backpressure. The modular cam-check includes a stainless steel spring and cam-arm, rubber faced disc and a replaceable seat. The body shall be manufactured from 300 series stainless steel, 100% lead free through the waterway, with a single two-bolt access cover. No special tools shall be required for servicing. Double Check Valve Assembly shall be an Ames Fire & Waterworks 2000SS series.

3000SS - The double check detector assembly consists of two independently operating, spring loaded check valves, two UL/FM, OSY resilient wedge gate valves, and bypass assembly. The bypass assembly consists of a meter (CFM or GPM), a double check including shutoff valves and required test cocks. Each cam-check shall be internally loaded and provide a positive drip tight closure against reverse flow. Cam-check includes a stainless steel cam arm and spring, rubber faced disc and a replaceable seat. The body shall be manufactured from 300 series stainless steel, 100% lead free, through the water way, with a single two-bolt grooved style access cover. No special tools shall be required for servicing. Double Check Detector Assembly shall be an Ames Fire & Waterworks 3000SS series.

4000SS - The Reduced Pressure Zone Assembly shall consist of two independently operating, spring loaded cam-check valves with a hydraulically operated differential pressure relief valve located between and below the cam-checks, required test cocks and optional inlet and outlet resilient seat shutoff valves. When normal flow exists, both checks, called the zone, is at least 2 PSI lower than the inlet pressure. The differential pressure relief valve is closed during the normal flow.

If cessation of normal flow occurs, the differential pressure relief valve will automatically open and discharge to maintain the zone at least 2 PSI lower than the inlet pressure. This action will prevent a backflow or backsiphonage condition. After the required differential is established, the differential pressure relief valve again closes.

The cam-checks include a stainless steel spring and cam-arm, rubber faced disc and a replaceable seat. The body shall be manufactured from 300 series stainless steel, lead free through the waterway, with a single two-bolt grooved style access cover. No special tools shall be required for servicing. The relief valve shall be compact with a rolling diaphragm and no sliding seals. The relief valve shall discharge in a 360º radius. The Reduced Pressure Zone Assembly shall be an Ames Fire & Waterworks 4000SS series.

5000SS - The Reduced Pressure Detector Assembly shall consist of two independently operating, spring loaded cam check valves with a hydraulically operated differential pressure relief valve located between and below the cam checks, required test cocks, bypass assembly and inlet and outlet resilient seat shut off valves. When normal flow exists, both check valves are open and the pressure in the area between the checks, called the zone, is at least 2 PSI lower than the inlet pressure. The differential pressure relief valve is closed during normal flow.

The cam checks include a stainless steel spring and cam arm, rubber faced disc and a replaceable seat. The body shall be manufactured from 300 series stainless steel, lead free through the waterway, with a single two-bolt grooved style access cover. No special tools shall be required for servicing. The relief valve shall be compact with a rolling diaphragm and no sliding seals. The relief valve shall discharge in a 360º radius. the bypass line consists of a small diameter reduced pressure zone assembly, water meter and shut-off valves. The Reduced Pressure Detector Assembly shall be an Ames Fire & Waterworks 5000SS series.
