WATER PRESSURE REDUCING VALVES MADE IN THE USA NOW! 2- Year Warranty

2 Customer Service 1-704-841-6000 AUTOMATIC PRESSURE REDUCTION Pressure reducing valves are designed to automatically reduce a high inlet pressure to a lower outlet pressure. In most plumbing code jurisdictions, pressure reducing valves are mandated whenever water pressure exceeds 80 PSI. Excessive pressure can waste as much as 40,000 gallons of water in an average home every year. Ideally, water systems can meet required pressure and capacity needs with a water velocity of 10 feet per second or less. THE VALUE OF ECONOMIZING Cutting costs by specifying undersized piping often results in water...

www.apollovalves.com 3 Water Pressure Reducing Valves Apollo pressure reducing valves are shipped in the OPEN position. Their internal seat is held open by a compression spring pushing down. Compression is applied to the pressure spring by an adjusting screw working on a spring button. The standard setting is 50 psig. During static (no-flow) conditions, the valve is closed because the diaphragm force is greater than the valve spring force. The amount of force on the diaphragm by the valve spring determines the outlet — the reduced pressure downstream of the regulating valve. Outlet pressure drops...

Water Pressure Reducing Valves 4 Customer Service 1-704-841-6000 FOR RESIDENTIAL & LIGHT TO MEDIUM COMMERCIAL APPLICATIONS Apollo PR Series pressure reducing valves provide automatic control of excessive water pressure and problem supply fluctuations. These models are designed to reduce pressures of up to 300 PSI to a more manageable range. Factory set at 50 PSI, they adjust with a turn of a screw. They feature a built-in by-pass and strainer, and comply with ASSE 1003 and CSA B356 standards. They are listed with IAPMO and the City of Los Angeles. PR Series valves are built for long, reliable...

PRH pressure reducing valves’ integral by-pass protects against thermal expansion. Built for extended service, these models include bronze body construction and stainless steel replaceable seat. They are designed to meet ASSE, CSAand IAPMO standards. These heavy-duty...

Water Pressure Reducing Valves 1 0 Customer Service 1-704-841-6000 A single pressure reducing valve is used in typical residential and commercial applications. This installation demands that the valve handle all flow demands, from zero to full capacity. Using pressure reducing valves in series is recommended in applications in which the inlet pressure fluctuates greatly or exceeds the desired reduced pressure by 4 times or more. When using two pressure reducing valves in series, the first valve should be set to absorb approximately half of the pressure between the nominal supply pressure and...

www.apollovalves.com 11 Water Pressure Reducing Valves SPECIALLY DESIGNED LOW PRESSURE MODELS Apollo’s low pressure reducing valves are designed to provide optimal performance low pressure (10 to 35 PSI) for residential and commercial applications. They feature a heat-resistant diaphragm for extended-term performance in automatic dishwashers, booster heaters and similar applications. FLOW/PERFORMANCE CURVES Apollo offers performance curves for every version of its PR Series pressure reducing valves. All curves plot the rate of flow against the reduced pressure fall-off.
