Water pressure regulator and reducer RDNT

for airfor gasfor compressed air

Overview
The Model RDNT is a direct-acting pressure reducing valve designed for series pressure reduction in building water systems and for industrial liquid and gas applications. It provides high flow capacity with low pressure loss and supports horizontal or vertical installation. For high-rise systems, an upstream water hammer arrester is recommended to limit transients. Maintenance kits are available.

Key Features and Benefits

• Versatile compatibility: suitable for a wide range of liquids and gases in building and industrial systems.
• Enhanced flow efficiency: direct-acting design reduces pressure drop at higher flow rates.
• Automation-ready: compatible with process automation and industrial control systems.
• Flexible mounting: can be installed horizontally or vertically to fit site constraints.
• Adjustable outlet pressure: calibrated nut allows precise setting of downstream pressure.
• Stable regulation: balanced piston design maintains consistent outlet pressure despite inlet fluctuations; built-in pressure gauge provides outlet reading.
• Serviceable design: low-maintenance construction; maintenance kits available for routine upkeep.

Applications
Series pressure reduction in building water systems, high-rise building supply, industrial compressed air and gas systems, and general process applications requiring pressure limiting.

Installation and Operation
Mount horizontally or vertically according to piping layout. For high-rise or long-distance supply lines, install a water hammer arrester upstream to reduce effects of sudden pump shut-off. Note: RDNT is supplied without strainer; use model RDST if strainer is required.

FAQ

• Q: Can RDNT be used for air and gas? A: Yes — suitable for many industrial air and gas applications.
• Q: Is a strainer included? A: No — RDNT is without strainer; RDST includes a strainer.
• Q: Is a water hammer arrester required? A: It is recommended upstream for high-rise systems to reduce transient shocks and extend system life.
