Main Valves Model 106-PT / 106-PTC / S106-PT / S106-PTC Full Port, Double Chamber Hydraulically Operated Valve KEY FEATURES • Maintains positive control under all operating pressures • Precise positioning • Internal drop check option included on the PTC model • Available in globe and angle style 106-PT Globe Product Overview The 106-PT and 106-PTC series control valves are hydraulically operated by introducing or releasing water from the control chambers. PT and PTC valves have two operating chambers that are divided from each other by the diaphragm, and are separated from the flowing media by an adaptor plate. 106-PTC is an enhancement of the 106-PT and includes an internal drop check feature. This mechanical check provides non-slam closure on reverse flow, independently of the stem position or the pilot operation. PT and PTC valves are usually combined with Singer Valve specific purpose pilots and accessories to provide control for a wide range of functions: typically pump control and solenoid control applications. Refer to Main Valve Options on page 75 and Pilots & Accessories on page 259 to further customize the valve to suit specific applications. 1. Optional Model X129 Limit Switch Assembly 2.

Valves are sized to provide an appropriate pressure drop for each application. Valves usually exhaust to atmosphere Sizing is ultimately determined by the specific application. Refer to the capacity charts for general guidelines. Double-chambered automatic control valves are typically used for pump control. Other uses would include but not be limited to low-pressure differential applications. 106-PT...
