About Air Preparation

Valve With Neoprene Diaphragm

Valve With Neoprene
Diaphragm
And Gauge Port

For Use With: Water, Oil, Air, Inert Gas
Temperature Range: 32° to 180° F

These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

Valves with a neoprene diaphragm have higher flow rates than valves with a Buna-N diaphragm.

Gauge ports let you attach a pressure gauge to monitor outlet pressure.

Vibration-Damping Pressure-Regulating
Valves for Water, Oil, Air, and Inert Gas

For Use With: Water, Oil, Air, Inert Gas
Temperature Range: See Table

A cast iron body absorbs vibration from pressure changes to reduce wear and noise in your pipeline. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

Internal strainers trap debris.

Heavy Duty Pressure-Regulating Valves for Water and Air

For Use With: Water, Air
Temperature Range: 32° to 180° F

Thicker walls and a 304 stainless steel seal make these valves tougher than brass pressure-regulating valves. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have an internal strainer to trap debris. Body is bronze for durability and a long service life.

Extended-Life Pressure-Regulating Valves for Water, Oil, Air, and Inert Gas

For Use With: Water, Oil, Air, Inert Gas
Temperature Range: 32° to 180° F

For a longer service life than brass and cast iron valves, these have a durable bronze body. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. All valves have an internal strainer to trap debris.

Pressure-Regulating Valves for Steam

For Use With: Steam
Temperature Range: -20° to 400° F

Automatically reduce a high, variable inlet pressure in your steam system to a lower, stable outlet pressure. Adjust the outlet pressure within the range. These valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

Internal strainers trap debris.

Manifold-Mount Compressed Air Regulators

Multiple Regulators Shown Installed (Manifold Sold Separately)

Mount these miniature regulators on a manifold (sold separately) to create a regulating manifold. Each regulator can be set to a different output pressure, so you can power multiple tools or machines with a single air supply. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.

Regulators with a panel-mount nut can be installed through a hole in a panel or enclosure. They let you hide your air lines without losing access to the control knob.
