Sanitary Gauge Guards

Keeping corrosive substances from touching pressure gauges used in food-processing and pharmaceutical plants, these guards have a sanitary design. Made of 316 stainless steel, they won’t rust from frequent washdowns with harsh cleaners and sanitizers. They have continuously-welded seams and polished surfaces, so there aren’t any pits for bacteria to grow in. Removing them for cleaning and maintenance is easy thanks to their quick-clamp connection, which is sometimes called a tri-clamp.

Also known as isolators and diaphragm seals, these guards have a 316 stainless steel gasket to shield the pressure gauges from corrosion. Before use, fill the guards with fluid such as glycerin or silicone that’s suitable for food contact.

Pressure-Regulating Valves with Compression Fittings for Food and Beverage

Compression fittings bite down on hard metal and plastic tubing for a tighter seal than push-to-connect fittings. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. The Buna-N/stainless steel diaphragm and EPDM seal are FDA compliant 21 CFR 177.2600.

Sanitary Pressure Transmitters

For use in sanitary applications such as food processing, these transmitters are 3-A certified. They have a sanitary quick-clamp connection for easy disassembly in systems that require frequent cleaning. These transmitters are rated IP66, IP69K, and NEMA 4X to resist washdowns and corrosion. Also known as transducers, they convert pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. As pressure increases, the output signal from the transmitter will increase. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's pressure range and output signal. Transmitters are accurate only within the pressure range.

These transmitters connect using two wires to send a 4-20mA output current. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. Transmitters are compatible with M12 sockets.

Clean Room Pressure-Regulating Valves for Water, Air, and Inert Gas

To maintain contaminant-free standards in clean room environments, these valves come cleaned and bagged to Fed. Std. Class 100 and ISO Class 5 clean room standards and have a 316 stainless steel body with a smooth finish to resist dust collection. They automatically reduce a high, variable inlet pressure to a lower, stable output pressure. Adjust the outlet pressure within the range. Valves are no-bleed style, so they keep process media contained within the valve.

Sanitary Pressure-Regulating Valves

Regulate air, gas, and liquid pressure on food, beverage, and pharmaceutical lines with these valves—they’re 3-A certified to meet sanitary design standards. Attach them to your line to reduce a high, variable inlet pressure to a lower, stable outlet pressure.

Twist the T-handle on top of the valve to adjust the outlet pressure. When the valve is closed, a seal on the outlet prevents leaks and helps maintain consistent pressure. These valves meet ANSI/FCI 70-2 Class III, which means a maximum of 0.1% of fluid, gas, or air can escape while they are fully closed. The spring and valve mechanism are sealed behind the diaphragm, so contaminants can’t enter. Both the diaphragm and seals hold up to water, detergents, and chemicals. They’re also FDA compliant for direct contact with food.

Made of 316 stainless steel, these valves won’t corrode from frequent washdowns with harsh cleaners. They connect to your line with quick-clamp sanitary fittings, also known as tri-clamp connections, which are easier to remove and sanitize than threaded connections. The polished interior is extremely smooth, so there’s nowhere for bacteria to hide. They’re also self-draining, so liquids drain completely and don’t contaminate your line. Keep these valves open during clean-in-place (CIP) cycles with a locking pin.

Sanitary Back-Pressure-Regulating Valves

Designed to meet 3-A sanitary standards, these valves regulate liquid, gas, and air pressure in hygienic zones of food and beverage plants. They’re often used at the end of pipelines on processing and sanitizing equipment. Made of 316 stainless steel, they won't corrode from frequent washdowns with harsh cleaners. With an extremely smooth interior that self-drains, bacteria won't have time or space to grow. The spring and internal valve mechanisms are sealed off behind the diaphragm, which also prevents contamination. They connect with quick-clamp fittings, so disassembling to clean your line takes little time.

These valves obstruct flow to maintain sufficient operating pressure in your system. If the system pressure exceeds the set pressure, they exhaust through the outlet. They meet ANSI/FCI 70-2 Class III standards for shut-off valves, meaning a maximum of 0.1% of fluid, gas, or air will escape through the outlet when they’re closed. An integrated T-handle lets you set the outlet pressure without additional tools. The diaphragm and seal resist repeated exposure to water, and they’re FDA compliant for direct contact with food.

Clean Room Compressed Air Filter/Regulators for Particle Removal

Assembled, inspected, and packaged in a clean environment, these filter/regulators come sealed in antistatic double bags. The filter and regulator are joined top-to-bottom to fit in the same space as a filter alone. They provide clean compressed air at your required pressure. The filter has a clear bowl, so you can see inside to monitor contents from every direction. The regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure. Run a tube from the open drain port to a disposal point, such as a drain pan or waste system.

Clean Room Precision Compressed Air Regulators

When precision and cleanliness are critical—such as semiconductor manufacturing and food processing—these regulators are cleaned and bagged in an ISO Class 3 clean room to prevent contamination. They deliver steady air pressure to generate precise, repeatable movement. A locking adjustment knob secures your settings to prevent accidental changes. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.
