• 4Matic  Direct-Acting: The direct-acting type operates with either a flat diaphragm or convoluted bellows. Completely self-contained, it does not need an external sensing line downstream to operate.
• 4Matic Internally Piloted Piston-Operated. This type incorporates a pilot and main valve in one unit. The pilot valve has a design similar to the direct-acting valve. The discharge from the pilot valve acts on top of the piston, which opens the main valve.
• 4Matic  Externally Piloted. In this type, double diaphragms replace the piston operator of the internally piloted design. This increased diaphragm area can open a larger main valve, allowing a greater capacity per line size than the internally piloted valve.
• pressure reducing and pressure sustaining valves are based on the 106-PG or 206-PG main valve with the addition of the sustaining pilot 81-RP and pressure reducing pilot PR-160.
• Provided the upstream pressure setting is satisfied, the 81-RP pilot is kept open, permitting the valve to be controlled by the 160 pilot. The 160 pilot senses downstream pressure and under flowing conditions, it reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm.
• Should high demand cause the inlet pressure to fall to the 81-RP pilot setting, the upstream pressure has priority and the valve will modulate to prevent the upstream pressures from dropping below the set-point.
• When the valve is modulating to sustain upstream pressure above the minimum 81-RP pilot set-point, the downstream 160 pilot may try to open the valve to maintain its set-point, but upstream has priority and downstream pressures will fall below expectations.
• In typical applications, the reduced port model 206-PR-R is often the best selection.
• Excellent low flow stability
• Ensures minimum upstream pressure
• Easily and precisely set downstream pressure
• Pressure Reducing and Check Valve
• The pilot valve senses the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The downstream pressure is maintained relatively steady at the pilot set-point.
• The pilot check valves direct downstream pressure above the diaphragm to close the valve when the system pressures reverse (when the downstream pressure is higher than the upstream).
• Excellent low flow stability
• Drip-tight closing on return flow
• Easily and precisely set downstream pressure

• Known for Performance and Reliability
• In day-to-day plant operation, you have a long list of concerns, like meeting production schedules, maintaining product quality, and improving the efficiency of plant utilities, to name just a few. The last thing you should have to worry about is the performance of your plant's control valves. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds to compensate for the load disturbance and keeps the regulated process variable as close as possible to the desired set point.
• Pneumatic Globe Control Valve opening or closing is done automatically by pneumatic actuators (Spring & Diaphragm Type). Positioners are used to control the opening or closing of the actuator based on pneumatic signals. These control signals, traditionally based on 3-15psi (0.2-1.0bar), more common now are 4-20mA signals for industry. Solenoid Valves is being used for On/Off or Mixing-Diverting Application. The most common and versatile types of control valves are linear stem Globe Control Valves. Various option of Globe Control Valve available that make them suitable for a variety of process applications, including severe service.
• A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.
