Control steam line pressure with ±1 psi accuracy. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline. They meet ANSI/FCI 70-2 Class IV for tight shut-off (max. leakage rate of 0.01%). Install 1/4 NPT male pipe (not included) between the control valve and your downstream steam line.

Repair kits (sold separately) include replacement seals, diaphragm, spring, and spring assembly.

Regulate steam pressure in wet environments and harsh conditions with these valves that have a 316 stainless steel body for exceptional corrosion resistance. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range.

These valves meet ASME Code Section I for use with steam power boilers requiring pressure relief above 15 psi. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. For remote discharge, attach a drain line to the threaded relief port. Valves have a durable bronze body for a long service life.

EPR rubber seals provide better leak protection than brass seals.

Swivel test levers rotate 360° around the valve for use in areas with limited clearance.

For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV. All spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. Body is bronze for durability and a long service life.

Vented relief ports exhaust discharge directly.

Threaded relief ports can be attached to a drain line for remote discharge.

Vent carbon dioxide and other gases out of your container without letting dust, oxygen, and other contaminants in. Fill these airlocks with water or a sanitizing solution and they form a liquid seal. They’re often used in fermentation, such as beer and wine making, as well as other jobs where chemical reactions or temperature changes produce gas inside your container. A cap blocks out dust even as it vents the gas.

Push these airlocks into flasks, carboys, and other containers that have a rubber stopper with a hole. The airlocks come apart in three pieces for easy and thorough cleaning—no need for specially shaped brushes to reach every crevice.
