Pressure Regulators, Vent Master, Stream Selection Valves

Parker offers a range of high pressure and general purpose regulators for instrumentation and process control applications. Instrumentation regulators are used in the process, power, oil, gas and semiconductor industries to control the flow of liquids and gases with speed and precision. Air regulators provide quick response and accurate pressure regulation for the most demanding industrial air preparation applications to meet a variety of service needs. All regulators are built to the highest quality standards, recognized around the world for their performance, durability and reliability.

Vent Master: After a process sample stream is analyzed, it must be disposed of in a manner consistent with environmental regulations. Today, as in the past, it has been common practice to simply vent the sample stream to the atmosphere. As environmental regulations become more stringent, it is becoming undesirable, if not illegal, to admit these samples to the atmosphere. For an analyzer to operate correctly, it must be calibrated and operated under the same conditions. These critical conditions are temperature, flow and pressure, with the pressure of the measurement cell being the most critical. Venting analyzer effluent to atmosphere is not only convenient, but it also provides a very stable reference pressure for the analyzer measurement cell. In other words, the measurement cell “floats” on atmospheric pressure. The primary function of the Parker Vent Master™ is to isolate the analyzer from fluctuating outlet pressures by controlling the pressure of the collection header (commonly referred to as the Vent Header) and pumping the effluent sample gases into the fluctuating return system.

The Parker Gen II R-max™ is a multi-functional system capable of integrating both stream switching and filtering into one unique compact assembly. The system is designed to control both gases and liquids in analytical systems ranging from vacuum to 500 psig (34 bar) while requiring only 65 psig (5 bar) actuating air pressure. The system was engineered with a focus on improved product reliability and reduced cost of ownership. The Parker Gen II R-max™ Stream Switching System utilizes state-of-the-art surface mount technology to reduce leak paths, internal volume, and dead volume. With surface mounting, system components may be easily removed and replaced without breaking process connections. In addition, the Parker Gen II R-max™ system utilizes an internal self-purging outlet header to eliminate the need for an additional outlet loop.
