Parker Watts Fluid Air R119-08C Air Regulator

The Parker Watts Fluid Air R119-08C Air Regulator is a heavy-duty 1" NPT pneumatic pressure regulator engineered for high-volume industrial air preparation. Designed for systems requiring 0-125 PSI regulated pressure, this hi-flow air regulator handles up to 300 PSI primary inlet pressure and supports a massive 400 SCFM flow rate. Its rugged zinc body and balanced poppet design ensure rapid response and superior stability, even during significant fluctuations in downstream demand. The integrated relieving function allows for immediate venting of excess secondary pressure, while the secondary aspiration feature maintains accurate pressure regulation for critical tools and machinery. The heavy-duty T-handle adjustment provides technicians with precise tactile control during setup. Utilizing Buna-N seals and a brass inner valve, this high-flow pneumatic regulator is built for longevity in demanding environments like automotive manufacturing and large-scale HVACR distribution. Two 1/4" NPT gauge ports come standard for secondary pressure monitoring.

Key Benefits

• Industrial-Grade Flow Capacity: Rated for 400 SCFM to supply air-hungry tools and high-volume pneumatic circuits.
• Precision Pressure Stability: The diaphragm-operated balanced poppet maintains consistent output regardless of inlet pressure shifts.
• Rugged Componentry: Constructed with a durable zinc housing and steel adjusting screw to withstand harsh job site conditions.
• Efficient Downstream Relieving: The relieving design safely vents downstream pressure to prevent equipment over-pressurization.
• Standardized Plumbing: Features a massive 1" NPT female inlet/outlet for high-conductance piping systems.

Common Questions

Can the R119-08C handle surges in upstream pressure?
Yes, the balanced poppet design specifically isolates the sensing diaphragm from inlet pressure variations, ensuring your set 0-125 PSI range remains stable even if the compressor cycles or the main line spikes up to 300 PSI.

Is this regulator suitable for moist air environments?
While the Buna-N seals are resilient, performance at high flow rates can be affected by icing if excessive moisture is present. For optimal results, an upstream filter should be installed to protect the internal brass valve and zinc body.

What is the purpose of the dual 1/4" NPT ports?
These are dedicated gauge ports that allow you to install a pressure gauge on either side of the regulator body, providing flexibility in crowded manifolds while monitoring output pressure.
