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.

Compact Compressed Air Regulators

Panel Mount

A lower profile than our other compressed air regulators makes these regulators a better fit in tight spots. Use them to adjust and maintain the pressure of your compressed air. Install in your air line after filters.

Relieving regulators exhaust when the downstream pressure exceeds the set pressure. Panel-mount regulators have inlet ports on the bottom to easily connect air lines after mounting to your control panel.
