MAIN VALVES MODELS 106-PG / S106-PG SINGLE CHAMBER, HYDRAULICALLY OPERATED VALVE KEY FEATURES • Anti-cavitation option is ideal for high pressure drop situations • Available in globe and angle style PRODUCT OVERVIEW The 106-PG series control valve is designed to suit a large variety of applications such as pressure, flow or level control. This hydraulically operated valve introduces or releases water from the control chamber above the diaphragm to effectively maintain accurate water control Refer to Main Valve Options on page 62 and Pilots & Accessories on page 207 to further customize the valve to suit specific applications.

NSF 61 Fusion Bonded Epoxy Coating 1 Automatic control valves operate by introducing or exhausting water from above the diaphragm at controlled rates. A pressure differential is required and is either inlet to outlet or inlet to atmosphere, depending on the application. Valves are sized to provide an appropriate pressure drop for each application. Most valves require a minimum of 10 psi / 0.7 bar pressure drop to operate. This applies mostly to valves that have the bonnet vented to downstream. With minimum of 5 psi / 0.35 bar downstream pressure, many valves can be made to open fully by venting the bonnet to atmosphere. Singer control valves are designed for use with clean potable water. Applications for other media are possible. Consult with Singer Valve.

MODELS 106-PG / S106-PG SINGLE CHAMBER, HYDRAULICALLY OPERATED VALVE Careful consideration of the possibility of cavitation must be given. Anti-cavitation trim is available to control the cavitation, reduce noise and prevent damage. Refer to 106-AC (page 78) or consult with Singer Valve. The 106-PG single chambered valve is the basic valve used in practically every model bearing the 106 description. The pilot systems are designed to meet the functional and performance requirements of specific applications. Sizing is ultimately determined by the specific application. AVAILABLE OPTIONS Further...
