Sanitary Sampling Valves
- Valve Type: Stop Cock
- For Use With: Food, Beverage
- Specifications Met: FDA Compliant 21 CFR 177.2600, FDA Compliant 21 CFR 177.1550
Take liquid samples in sanitary environments—these sampling valves have a hygienic design, so they’re commonly used in breweries and wineries. With a body made of 316 stainless steel and a PTFE plastic seat, they resist the high temperatures and harsh chemicals of clean-in-place (CIP) processes. These valves have an extremely smooth surface, leaving no space for bacteria to grow. Quick-clamp connections, also known as tri-clamp fittings, are easily taken apart for regular cleaning. These valves are self-draining, so previous samples and cleaning chemicals won’t contaminate future samples. Both the seat and the silicone O-ring comply with FDA standards for direct contact with food and beverage.
To take samples, turn the thumb screw to open valves. Hang a bucket for sample collection from the bucket groove. Valves also have a leak detection port that will release a small amount of liquid to let you know when it’s time to replace all the valve seals.
Valves with a bent spout have a tab for connecting carbon dioxide testing devices. They’re often used for carbonated beverages. They shouldn’t be used with liquids that have solids in them, such as the grape skins or seeds in wine, as those can get caught in the outlet.

Sampling Valves for Fuel
- Valve Type: Ball
- For Use With: Butane, Diesel Fuel, Fuel Oil, Gasoline, Kerosene, Propane
- Seal Material: Graphite
- Specifications Met: American Petroleum Institute Standard 607, Edition 5
Fire-tested to meet American Petroleum Institute (API) 607, Edition 5, these valves are designed to securely isolate fluid and prevent the spread of fire. They’re often installed on petroleum loading arms to drain a small amount of fuel for inspection without interrupting flow. Turn the handle to divert a small amount of media to the sampling outlet or to shut off flow. Body is 316 stainless steel for excellent corrosion resistance. All valves are full port, so they do not restrict flow.

Fast-Acting Panel-Mount Threaded On/Off Valves
Open and close these valves with the flip of the toggle switch. Commonly used for equipment testing and gas sampling, they have threads and a hex nut below the handle for installation in instrument panels.
316 stainless steel valves are more corrosion resistant than brass valves.
Manual-return valves remain open or closed when the toggle is moved into position.
Spring-return valves automatically close when the toggle is released.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Fast-Acting Compact Threaded On/Off Valves
Compact
Push Button
Often used in testing and sampling applications, these valves open and close with the push of a button. They’re also known as push-button valves and are designed for installation in tight spots.
Normally open valves close when the button is pushed and spring open when the button is released.
Normally closed valves open when the button is pushed and spring closed when the button is released.
Valves with an exhaust port release media through a small, secondary output when they are closed. When valves are open, the exhaust port is closed.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Sanitary Sampling Stainless Steel Tube Fittings
- For Use With: Dairy, Beverage, Water, Air, Food
- Tubing: Use with welded 316/316L stainless steel
- Specifications Met: 3-A Certified 63-03
Take samples in sanitary environments—these tube fittings won’t contaminate your lines or force you to pause them. Made of 316L stainless steel, they’ll stand up to harsh cleaners and sanitizers without corroding. They also have polished internal surfaces, minimizing the space where bacteria could grow. With quick-clamp connections, they are easy to take apart for cleaning or reconfiguring your line. All are 3-A certified to meet sanitary design standards, so they’re often used in food and beverage, pharmaceutical, and biotech applications.
All fittings require pierceable lids (sold separately) to draw samples through a hypodermic needle. Each lid is good for seven samples, and each sample leaves a hole mark, so you know when it’s time to unscrew the nut on the tube fitting and swap in a new lid. To help prevent dust and moisture from accumulating on the lid, all tube fittings have a dust cover. These lids are FDA compliant, so they keep contaminants from entering your line and also are approved for direct contact with food if they break off and fall in. Manufactured free of contaminants and allergens, all are BPA-, latex-, and phthalate-free. They’re also TSE/BSE compliant, meaning they’ve never come into contact with any animal products.
Pair these tube fittings with liquid samplers for a sample. They use gravity to draw out liquid through the needle directly into the bag.

Steel Bleed Rings
- For Use With: Air, Natural Gas, Oil, Steam, Water
Access the inside of a pipe line to vent pressure, drain liquid, or take samples. These bleed rings act as a port where two pipe flanges meet, so you don’t have to disassemble your flanges to get inside. They include a plug, or you can attach your own fitting, valve, or probe. Made of steel, these bleed rings should be used in noncorrosive environments to prevent rusting.
Install these bleed rings between two pipe flanges along with a gasket on both sides to avoid leaks. They’re designed to fit flanges that meet ASME B16.5.

Stainless Steel Bleed Rings
- For Use With: Air, Natural Gas, Oil, Steam, Water
Create an access point in a pipe line where corrosion is a concern. Often used to relieve pressure or siphon and sample liquids, these bleed rings act as a port between two pipe flanges, eliminating the need to take apart your flanges to get inside. They include a plug, or replace the plug with your own fitting, valve, or probe. Made of stainless steel, these bleed rings resist rusting.
Install these bleed rings between two pipe flanges along with a gasket on both sides to avoid leaks. They’re designed to fit flanges that meet ASME B16.5.
304 stainless steel bleed rings keep corrosion at bay in wet conditions but will start to corrode when exposed to salt water. 316 stainless steel bleed rings withstand wet conditions as well as chemicals and salt water.
