R
PRESSURE SUSTAINING VALVE with SOLENOID (On-Off) and HYDRAULIC CHECK FEATURE
01/05
Stainless Series
Operation
The Solenoid Pilot will either open to allow regulating action, or close the valve drip-tight when energized.
Specify energize to open or close the Main Valve and voltage PRIOR to ordering.
If downstream pressure becomes greater than upstream pressure, downstream pressure is admitted to the main valve cover chamber, closing the valve and preventing reversal of flow. Normal backpressure or sustaining operation resumes when upstream pressure exceeds downstream pressure.

When the valve is located “in line” connecting two distribution zones, the valve acts as a Pressure Sustaining Control Valve. When pressure in the upstream zone falls below the pilot setting, the valve
modulates toward a closed position, sustaining pressure in the upstream zone. The valve will close, if necessary, until upstream pressure is above the pilot setting. The valve should be specified to include the optional opening speed control and position indicator when used for Pressure Sustaining applications.
Installation Guidelines
Prior to installation, flush line to remove debris.
Install valve horizontally “in line” (cover facing UP), so flow arrow matches flow through the line. Avoid
installing valves 6” or higher vertically. Consult factory prior to ordering if installation is other than described.
Install inlet and outlet isolation valves. NOTE: When using butterfly valves, insure disc does not contact control valve. Damage or improper valve seating may occur.
Provide adequate clearance for valve servicing and maintenance,
Install pressure gauges to monitor valve inlet and outlet pressure.
Connect Solenoid to proper electrical source in compliance with local electrical codes.
